          SpiNNaker : un supercalculateur qui émule le cerveau humain      Cache   Translate Page      

Construit par l'Université de School of Computer Science de Manchester, SpiNNaker est le plus grand supercalculateur neuromorphique au monde. Il est conçu et construit pour fonctionner de la même manière que le cerveau humain. Il vient d'être équipé de son millionième cœur de processeur emblématique et il a été mis sous tension pour la première fois vendredi 2 novembre 2018.

La nouvelle architecture "Spiking Neural Network Architecture" ou "SpiNNaker ", dotée d'un million de processeurs, est en mesure de réaliser plus de 200 millions de millions d'actions par seconde, chacune de ses puces comportant 100 millions de transistors.

Le projet a nécessité 15 millions de livres de financement, 20 ans de conception et plus de 10 ans de construction. SpiNNaker peut modéliser plus de neurones biologiques en temps réel que toute autre machine de la planète.

Les neurones biologiques sont des cellules cérébrales de base présentes dans le système nerveux qui communiquent principalement en émettant des "pics" d'énergie électrochimique pure. L'informatique neuromorphique utilise des systèmes informatiques à grande échelle contenant des circuits électroniques pour imiter ces pointes dans une machine.

SpiNNaker, contrairement aux ordinateurs traditionnels, ne communique pas en envoyant de grandes quantités d'informations du point A au point B d'un un réseau standard. Au lieu de cela, il imite l'architecture de communication massivement parallèle du cerveau, envoyant des milliards de petites quantités d'informations simultanément vers des milliers de destinations différentes.

Steve Furber, professeur en génie informatique, à l'origine de l'idée initiale d'un tel ordinateur, explique: "SpiNNaker repense complètement le fonctionnement des ordinateurs classiques. Nous avons essentiellement créé une machine qui fonctionne plus comme un cerveau qu’un ordinateur traditionnel, ce qui est extrêmement excitant.

L'objectif ultime du projet a toujours été de créer un million de cœurs dans un seul ordinateur pour les applications de modélisation du cerveau en temps réel, et nous l'avons maintenant atteint, ce qui est fantastique."

L'objectif final est de modéliser jusqu'à un milliard de neurones biologiques en temps réel et les cheurcheurs sont maintenant plus proches. Pour donner une idée de l’échelle, un cerveau de souris est constitué d’environ 100 millions de neurones et le cerveau humain est 1000 fois plus gros que cela.

Un milliard de neurones correspond à 1% de l'échelle du cerveau humain, qui comprend un peu moins de 100 milliards de cellules du cerveau, ou neurones, qui sont tous fortement interconnectés via environ 1 quadrillion de synapses 

L'une de utilisations fondamentales de SpiNNaker est d'aider les neuroscientifiques à mieux comprendre le fonctionnement de notre cerveau. Pour ce faire, il exécute des simulations en temps réel à très grande échelle, ce qui n’est tout simplement pas possible sur d’autres machines.

Par exemple, SpiNNaker a été utilisé pour simuler un traitement en temps réel de haut niveau dans une gamme de réseaux cérébraux isolés. Cela comprend un modèle de 80 000 neurones d'un segment du cortex, la couche externe du cerveau qui reçoit et traite les informations provenant des sens.

Il a également simulé une région du cerveau appelée ganglions de la base - une zone affectée par la maladie de Parkinson, ce qui signifie qu'elle présente un potentiel énorme en percée neurologique en science, comme les tests pharmaceutiques.

La puissance de SpiNNaker a récemment été exploitée pour contrôler un robot, le SpOmnibot. Ce robot utilise le système SpiNNaker pour interpréter les informations visuelles en temps réel et naviguer vers certains objets tout en ignorant les autres.

Le professeur Furber ajoute:"Les neuroscientifiques peuvent désormais utiliser SpiNNaker pour percer certains des secrets du fonctionnement du cerveau humain en exécutant des simulations à grande échelle sans précédent. Il fonctionne également comme un simulateur de neurones en temps réel qui permet aux robotiques d’intégrer des réseaux de neurones à grande échelle dans des robots mobiles afin qu’ils puissent marcher, parler et se déplacer avec souplesse et faible consommation."

          AMD outlines its future: 7nm Zen 2, Zen 3, Zen 4      Cache   Translate Page      
On the CPU side of things, AMD talked extensively about the forthcoming Zen 2 architecture. The goal of the original Zen architecture was to get AMD, at the very least, competitive with what Intel had to offer. AMD knew that Zen would not take the performance lead from Intel, but the pricing and features of its chips made them nonetheless attractive, especially in workloads that highlighted certain shortcomings of Intel's parts (fewer memory channels, less I/O bandwidth). Zen 2 promises to be not merely competitive with Intel, but superior to it. Key to this is TSMC's 7nm process, which offers twice the transistor density of the 14nm process the original Zen parts used. For the same performance level, power is reduced by about 50 percent, or, conversely, at the same power consumption, performance is increased by about 25 percent. TSMC's 14nm and 12nm processes both trail behind Intel's 14nm process in terms of performance per watt, but with 7nm, TSMC will take the lead.

These Zen 2 processors using the 7nm process will hit the market in 2019, so it seems like next year is the perfect moment to make any transitions from Intel to AMD. Intel has been milking its 14nm process for all its worth, because it just can't seem to get its 10nm process to work properly. With AMD moving to 7nm, it definitely seems the company will actually leapfrog Intel next year.


          The Second Chechen War: Testimony of an Eyewitness      Cache   Translate Page      

Chechen journalist Abdul Itslayev lived out the Second Chechen War in his native village. Against a backdrop of rocket attacks, murder and robbery, he tried to piece together what, in fact, was happening. RU

Illustration by Polina Zaslavskaya. All rights reserved.

Note from the editors: In August 1999, Russian forces started a brutal air campaign against Chechnya, killing and forcing tens of thousands to flee. Weeks later, after a series of apartment block bombings in Russia, President Putin declared the Chechen President and parliament illegitimate, and ordered a ground invasion.

Abdul Itslayev experienced this conflict in his home village of Goiskoe, located in the Urus-Martan district, south-west of Grozny, the capital. Here we publish an excerpt of his forthcoming memoirs. 

The second war arrived in my native village of Goiskoye on Friday 10 September, 1999.

There were two rounds of aerial bombing, the first at 11.30, the second at 13.30. Their targets: a television relay station and a bridge spanning the Goitinka River. Residential houses were destroyed as well. Flying fragments injured Akho Bakayev and killed old Zelimkhan Ibiyev on the spot.

On a road not for from the bridge, a car carrying my neighbour and teacher Mansur Eskiev and his wife and children was riddled with holes. On the second morning they all set off for Georgia, and from there to Europe.

My own house didn’t escape unscathed. A dozen fragments struck the roof and another flew in through a window and lodged itself in the wall. I’d built my two-room khibara (hut) the year before using materials salvaged from the ruins of my parents’ house, destroyed during the first war. My hut may have resembled a barn more than anything else, but I delighted in it as if it were a palace. Having a roof over your head is any refugee’s dream. And that’s what I was, having spent over two years homeless.

Fifty metres from there, on the site of the destroyed house, stood my mother’s home. Built out of used brick, it boasted a slate roof and a basement – the only one in the whole area. Neighbours would take refuge there during air raids and shelling. My mother lived with my sister and four brothers. We built this house between June and December 1996, coming in to do so from Urus-Martan, where we spent over a year living in the partially constructed house of a friend after our village was destroyed.

The air strikes shredded the power lines. The pumping station ceased to function in the absence of energy. We got water from the river. After it rained, the water was a mixture of sand and clay - and the sediment would fill half a bucket.

No outsiders set foot in the village. This, everyone had decided, was Goiskoye’s fate: to be crushed by war for a second time

Our only connection with the outside world was an old transistor radio. Commenting on the movements of the army in Chechnya, General Manilov, representative of the Russian General Staff, would often mention Goiskoye. The strikes, he said, were being conducted against militant targets, even though there were absolutely nowhere to hide in the places he was talking about. Everything had been obliterated and bombed out back in 1996.

No outsiders set foot in the village. This, everyone had decided, was Goiskoye’s fate: to be crushed by war for a second time. Those who’d stayed put in the settlement numbered some four dozen people.

In early December, the shelling began to intensify. Military forces massed in the immediate vicinity of Urus-Martan.

They had missiles that detonated just above the ground, and they proved to be terrible weapons. Buildings ended up riddled top to bottom with fragments. Remaining in the village was no longer possible. Taking advantage of a window between raids, we relocated to my cousin’s place in neighbouring Alkhazurovo. Eight families holed up in the same house. Under a canopy in the yard was a dugout shelter for children and women.

The war, meanwhile, was following close on our heels. On the approach to Alkharzurovo, aerial strikes destroyed a Moskvich car and a motorbike being used by Salambek Soslambekov and Mumaid Gabzayev to transport some household things. Both Soslambekov and Gabzayev perished; Lom-Ali Ingayev sustained a knee injury.

The first sweeps

That morning, all Alkhazurovo was talking about a column of militants.

Leaving Urus-Martan, they’d retreated to the Argun River gorge via Martan-chu, Goy-chu and Alkhazurovo. There were no Russian planes in the air while the column was on the move. The artillery remained silent the whole night through. We were far from the “big road” and neither heard nor saw the militants. The next morning brought more news: Akhmed Zakayev had stopped here for the night but left in the small hours and said that he’d be relocating to Georgia.

In the evening, a car pulled up by the gates. I came out to the car and saw Adam Gatsayev. Around three years younger than me, he’d once been my student. The period between the two wars saw him working for the village administration. He had news, and a question to ask me:

“Military forces have entered Urus-Martan. Representatives from three villages – Alkhazurovo, Goy-chu and Goiskoye – have been summoned there by Shamanov. Delegations will be travelling over from the first two, but we’ve no one to send. Yunus did promise but he’s old and sick. Come tomorrow he might not even be able to get up – or he might change his mind. Maybe your brother could make the journey with me?”

“That’s no place for my brother to be. If Yunus can’t or won’t go, I’ll go myself.”

After returning from Urus-Martan, Adam waited for me on the outskirts of Alkhazurovo. I squeezed my body, heavy with fatigue, into the Zhiguli. Adam told me what had happened en route:

“People had gathered from all over the district. Shamanov welcomed them in person. All the military men were seriously well oiled and there was a whole sea of vodka waiting to be drunk. And all this in the t mosque the Wahhabists built in the central square. Shamanov made a speech. He said that Goiskoye had given him a massive headache during the first war as well, and that now his intelligence operatives had been taken out there.”

“What operatives? I’ve not heard anything about this…”

“I understand that a Russian reconnaissance group encountered a group of militants who’d retreated from Urus-Martan. They took out an armoured personnel carrier... Shamanov promised to be in Goiskoye tomorrow at noon. The sweep will follow, whereupon the population will be able to return. That’s what Shamanov said.”

Vladimir Shamanov was the general who destroyed Goyskoye. Back in 1996, he’d also summoned village elders for negotiations outside Alkhazurovo and set them conditions that couldn’t be fulfilled. Then he summoned the helicopters. “At least allow the women and children to be evacuated!” they implored him. “No!” he replied.

The column was crawling along. Yards and houses were searched from top to bottom, basements and attics included. Anything that aroused the slightest suspicion was subjected to a microscopic examination

We, Adam and I, decided: Shamanov wouldn’t be coming tomorrow, and the sweep would commence in the morning. We needed to arrive in the village before the soldiers.

On the way to Goiskoye, Adam told me more about the previous day’s meeting. The district now had leaders chosen or appointed by God knows who. We too had just a single card to play: if anyone asked, we’d say we were local officials. The village streets were absolutely deserted. Adam parked the Zhiguli in my mother’s yard. Shana spent five minutes telling us about the events of the previous night– but then armoured vehicles materialised at the far end of the street, along with soldiers inching along fences.

We headed towards them, keeping strictly to the middle of the road. No words, no unnecessary movements. Like tin soldiers. The APCs stopped. Someone dropped to one knee and took aim at us. The butts of automatic rifles were poked into our napes, backs and stomachs:

“Who’re you?”

“Local officials. Tell your commander we’re here.”

Someone spoke into a walkie-talkie behind us. We were nudged onward: “Go! The commander’s at the end of the column.” The column was a good kilometre long. Before we reached the end we were stopped another dozen times, prodded with automatics, showered with profanities and sniffed by Alsatians.

Finally, we came upon a middle-aged military man wearing an astrakhan hat.

“I’m the commander of the internal troop brigade,” he said. “What did you want?”

“This is the first sweep. You ought to warn people, calm them down. We were expecting you at noon.”

“You have half an hour. Tell everyone: don’t lay a finger on my guys and I won’t lay a finger on you. I give you my word.”

Who had stayed put in the village? On what streets? Did they have documents or didn’t they? We were two ordinary guys, just like everyone else, we enjoyed no authority. But there was no doubt about it: people would listen to us.

Illustration by Polina Zaslavskaya. All rights reserved.Half an hour later we were back at the end of column. The colonel addressed us brusquely:

“Come with me. You’ll leave once the sweep is over. Yesterday,” he added, “they finished their inspection of Urus-Martan. 27 residents in the whole town. Would you believe it!”

The column was crawling along. Yards and houses were searched from top to bottom, basements and attics included. Anything that aroused the slightest suspicion was subjected to a microscopic examination. Reports and orders sounded over the walkie-talkie. Trailing two steps behind the officer, we heard someone exclaim in surprise: “Dirt-poor village, this is!”

The colonel glanced over at us: had we made out these words?

“Two years ago all this was just ruins,” said Adam. “At least there’s something here now.”

Another report over the radio:

“We’re here in the southern zone, we’ve just stopped a Moskvich with three people inside and a bloody axe and knives under the seat. We’ve roughed them up a bit…”

I guessed who “they” were:

“They’re from Urus-Martan, butcher’s sons. They’ve holed up at their uncle’s, relocated to Alkhazurovo together with us. Order them not to be beaten.”

“Don’t touch them until I arrive,” ordered the colonel.

All three were stood by the flung-open doors of the Moskvich, muddied, bruised, one of them with blood on his face. Recognising me, they addressed me by name, and I by theirs.

“Let them go on their way,” said the commander.

Illustration by Polina Zaslavskaya. All rights reserved.This was the first and last sweep to have involved next to no bloodshed. All the subsequent ones – and, in the first year of the counter-terrorism operation, they were conducted at least two or three times monthly – featured arrests, beatings, zindans (underground prisons), fingerprinting, widespread looting.

The second sweep followed a different playbook. The village was blocked off to the world before sunrise: no exit, no entry. The two generals in charge of the special op – Yakov Nedobitko and Viktor Medveditskov – stationed themselves on the village’s southern outskirts, near a roadblock. Close by was the filtropunkt (“filtration point”) to which all male residents aged 12 to 65 were being herded. Later, an old quarry in the north-eastern outskirts was transformed into a filtropunkt (and fingerprinting facility) as well.

If the first sweep didn’t fray people’s nerves, all restraints were now cast aside: rudeness, boorishness, high-handedness... Complaints from all sides: “They confiscated this, took away that, stole this, made off with that.”

Even my hut was picked clean. The items taken included old notebooks, a camera, a Dictaphone, a couple of t-shirts, and a honey harvesting tent. The hives themselves weren’t touched.

We now faced our first “official” ransom demand: one ram.

A relative fleeing Chechnya had left a Mercedes in Uvais Kayev’s yard. As for the documentation and keys, he either took them with him or left them in someone’s keeping. Whose? This remained a mystery. Some military men smashed one of the windows, opened the door, combed the interior of the car. The trunk wouldn’t open, not even with the help of a crowbar. So the officer laid down a condition: “Either you cough up a ram or the car gets towed!”

“The old master of the house has no sheep.”

“There’s sheep in the village. He can buy one.”

Long story short: a ram took a ride in the last car involved in the special operation.

Death squads come to Urus-Martan

The “federals” reported the coordinates of the mass grave site in the old quarry. Close by stood the 245th Motorised Rifle Regiment (notorious for its atrocities) and a regiment under the command of Colonel Yuri Budanov. Even before his arrest and trial, Budanov was, how to put it, a familiar face to everyone. Everyone knew about his conflict with Khavazhi Dzhambulatov, the administration chief of the village of Tangi-chu. The colonel fought him and was beaten on more than one occasion.

Flash-forward to a courtroom in Rostov-on-Don in 2003. Budanov glanced at the next witness, Dzhambulatov, and asked, his voice full of anxiety: “How did you get here?”

“You and I are both here on your account…”

But this was still yet to come. Back in the present, people were angry after the bodies of 69 people had been uncovered, near Urus-Martan at the start of 2000. The anger and indignation could lead pretty much anywhere, and so the “federals” refused to honour their promise – to show people another three burial pits.

Most of the corpses in the mass grave had been laid out in a row, face up, and covered with tarpaulin and earth. Bodies in another mass grave discovered north-east of the village of Novye Varandy, on the banks of the Argun, had been “committed to the ground” in identical fashion. This area was within the responsibility zone of regiments stationed outside Tangi-chu. Later, corpses of residents detained in villages on the banks of the Argun were found scattered in Tangi-chu cemetery.

In the evenings, the curfew forced the town’s denizens into their homes. The streets became the domain of forces what were soon dubbed “death squads” by local residents

People returned to Urus-Martan; public transport started working again, as did the market. In the afternoons, the centre was completely full. But the town was buzzing like a hive about to disgorge a swarm of bees. Not a day passed without someone being killed or kidnapped...

In the evenings, the curfew forced the town’s denizens into their homes. The streets became the domain of forces what were soon dubbed “death squads” by local residents. They freely bypassed roadblocks and initially didn’t even cover up the side numbers of armoured personnel carriers and infantry fighting vehicles or the registration marks of UAZs and Zhigulis.

When the victim count rose into the hundreds, the town authorities were finally able to secure the consent of the military commandant’s office to nightly patrols by (unarmed) local residents. These patrols took control of key intersections and streets, documenting and suppressing any unauthorised movements. The murders and kidnappings stopped. A week later, however, the patrol parties formed by the locals began to come under fire. They ought to have been reinforced, made capable of striking back. The military, however, had decided otherwise – and banned the townspeople from going on patrol…

The death squads once again became the sovereign masters of Urus-Martan after dark. Among their victims were two imams from the congregational mosque (Umar Idrisov and Hasmagomed Umalatov), officials from local government agencies and security services, old people and young people.

The majority of the people who were kidnapped were unaccounted for. Some were found killed, tortured to death. Their remains were most often discovered in orchards outside Urus-Martan which had gone wild in the course of two wars.

There were two kidnappings in Goiskoye. Abducted directly from his house, Movldi Umayev struggled free and fled… only to be struck down by machine-gun fire. Aindi Dudurkayev, too, was dragged from his home at night by unknown individuals. Is he still alive? What fate befell him after his abduction, and where did it befall him? There’s no answer.

Without light or kerosene

A different situation was developing in neighbouring Goy-chu. There was a roadblock manned by Rybinsk OMON personnel on the main road to the north of the village. A motorised rifle regiment was stationed in the south, at the foot of the mountains. Meanwhile, the authorities were also putting the heat on the populace: “Your sympathies are with militants and you’re helping them out.” How exactly they were doing so remained unclear. Forget about a human slipping through the regiment’s lines – a woodland creature hadn’t a hope in hell of doing it.

In late February-early March, however, the bulwark was found to have a breach through which a small group of militants had made their way into the village. The group surrendered, and the military summoned the village residents to a meeting. The generals threatened to wipe the settlement from the face of the earth. But the village’s military commandant – a captain everyone knew (Volodya) – asked the generals not to call in the planes: “I have to live with these people, I have to work with them…”

A day or two later, people started talking about a second group of militants who’d managed to make it through the cordons. The voices of those who’d suddenly discovered a conspiracy between the military and the militants now began to make themselves heard. Quiet at first, these voices grew ever louder; the military had allegedly provided a corridor for the militants, and the latter, a detachment led by Arbi Barayev, advanced through it, proceeding via Goy-chu and Goiskoye. It immediately turned out that this occurred on a day when Goiskoye was subjected to yet another sweep. Having mentally reviewed its entire course, we suddenly discovered that a single empty farmstead had remained “unswept” in the village.

We drove down there and took a look. Footsteps from the gate led not to the house but to a cellar off to the side of it. The floor was thick with dirt left there by dozens of pairs of shoes. Who’d been hanging about here for so long – the “Barayevites” or the “sweepers”?

Illustration by Polina Zaslavskaya. All rights reserved.There was still no light, and kerosene for lamps wasn’t available. Your eyes quickly get tired in the candlelight. You could find yourself some transistor radio batteries at the Urus-Martan market and spend whole nights listening to news broadcasts on various frequencies. It was as though broadcasts out of Chechnya and about Chechnya weren’t about us at all. You sometimes heard something akin to the truth from Radio Svoboda and other foreign “voices”.

As for the reports on the new radio station Chechnya Svobodnaya (Free Chechnya), they were just pure fiction. Listening to them, you’d have thought we Chechens had one foot in a bright future and another in veritable ocean of bliss. According to Chechnya Svobodnaya, it was only yesterday that our children did no studying and had only ever held machine guns in their hands; and as for today, well…

My daughter entered Year 1 in September 1998. In September 1999, she ran home from school in tears as bombs and rockets rained down on us. Her school was housed in a prefabricated panel house allocated for that purpose by the UN High Commissioner for Refugees following the destruction of Goiskoye – and, specifically, the school – in the spring of 1996. Windows covered with polyethylene film. No light (nor would there be for another ten months). No heat (no gas, no wood, no coal). Roadside orchards and strips of forest cut down for firewood. Desks, tables, chairs all ramshackle. Teachers were mostly in Ingushetia, as refugees. Some were already in Europe...

Meanwhile, Russia’s presidential elections were scheduled for 26 March 2000. The bullet-riddled school was to be used as a polling station serving the settlements of Goiskoye and Michurina, with voter lists already being compiled.

How to make all of this out from Moscow, to say nothing of the provinces?

Massacre in Goy-chu

Daybreak brought the sounds of combat from Goy-chu.

The first news came a couple of hours later: something odd was happening, people were leaving their houses…

You could see from the Y-junction, from the roadblock that soldiers had formed a semi-circle around those people who’d managed to escape. According to two women who’d forced their way through the semi-circle, residents were cajoled and threatened back into their homes.

Towards evening, the denizens of Goy-chu had been convinced that the group of militants who had forced their way into the village were now neutralised and the village itself swept clean. No need to worry: federal forces were in control of the situation. The road to the village was completely blocked off. Neither Adam nor myself – nor, indeed, anyone desperate to know if their relatives were still alive – were allowed access to the settlement.

The din of the approaching battle floated in from Goy-chu throughout the night. Now, with the coming of morning, the village was being pounded by aerial and artillery strikes. Columns of military equipment were advancing through Goiskoye on their way to Goy-chu. At the crossroads between Alkhazurovo and Goy-chu, the carnage taking place in the latter was clearly visible: shells and rockets were tearing houses to shreds and sending plumes of smoke and fire into the sky.

Half a kilometre from the intersection, on the outskirts of the village, a vast crowd of men, women and children had amassed in a field. They had been encircled, and no one was allowed to leave the encirclement or to approach it. Here, at the fork in the road, the “operation’s” HQ had been set up in the military-occupied house of Visayev. Communicating through “intermediary” officers, residents of neighbouring settlements attempted to persuade the generals to release women and children from the encirclement. The generals, though, had other ideas…

The slaughter went on for over two weeks. Abating at night, the intensity of the battles would reach a peak by noon

Towards lunchtime, we learned the names of dozens of Goy-chu residents who’d failed to flee the village before the aerial and artillery strikes began. Then, after lunch, information filtered through that there was neither food nor warm clothing within the encirclement. People started putting together food packages in Goiskoye and Alkhazurovo and bread was brought over from Urus-Martan.

In a field next to the roadblock stood a battery of regimental mortars as well as Buratino rocket launchers. They were firing over the heads of the thousands of Goy-chu residents taken hostage by the military. These people’s houses, all their possessions, the village itself – it was being destroyed before their very eyes.

The slaughter went on for over two weeks. Abating at night, the intensity of the battles would reach a peak by noon. Having forced their way into the village from the south via the Goitinka River gorge, the militants reached the northern outskirts almost immediately. They were negotiated with, and then, after a turning point in the situation, methodically finished off – alongside local residents who hadn’t managed to flee the village in time.

Corpses... There were many of them. So many, in fact, that even six months, even a year later they wouldn’t let me sleep. Images of wounds, faces, clothing kept flickering before my eyes… They were brought in, freshly searched, either by military personnel conducting a post-battle sweep or else by the funeral team of the Ministry of Emergency Situations. Clothes unbuttoned, pockets turned out, often shoeless...

Each corpse was photographed and filmed. Dress, appearance, approximate age, possessions – all this was recorded. Their official papers rarely turned up, and these records were supposed to help identify them. And so it frequently proved: over half of the individuals committed nameless to the ground went on to acquire names. Some were identified immediately, and relatives would either take away the corpse or bury it here, alongside the others.

It wasn’t only Chechens from settlements near and far who were searching for “their own” among the dead. One day a Russian general arrived:

“My intelligence operatives never left this village. I was informed that the corpses of some non-Muslims with wire-bound hands were brought here yesterday...”

“There were no such corpses here.”

“I’d like my guys to take a look at yesterday’s corpses.”

They left their weapons in the vehicle, inspected a long row of dead bodies in the cemetery – and recognised not a single one. Nor would it have been easy to do so: identifying familiar features on mutilated bodies crushed by rubble or lying for weeks under the open sky isn’t a straightforward matter. Some, the charred ones, were completely unidentifiable. A bloody mess where the face should be. Noses and ears cut off, throats slashed. There wasn’t a single elderly face.

          AMD introduces 7nm Radeon Instinct MI60      Cache   Translate Page      
Today AMD unveiled its Radeon Instinct MI60 graphics card. 7nm Graphics Card(s) David Wang, SVP at Radeon Technologies Group, introduced the world's first 7nm graphics processor. Radeon Instinct MI60 is the first AMD graphics card to offer a bandwidth of 1 TB/s, thanks to four HBM2 stacks with up to 32GB of capacity. The Instinct MI60 is based on refined Vega 20 architecture, which features 13.23 billion transistors packed in a 331 mm2 die. The card is equipped with 4096 Stream Processors paired with 32GB of HBM2 memory. The Instinct MI60 is also the first graphics card to support PCIe 4.0...

          AMD Announces Radeon Instinct MI60 & MI50 Accelerators: Powered By 7nm Vega      Cache   Translate Page      

As part of this morning’s Next Horizon event, AMD formally announced the first two accelerator cards based on the company’s previously revealed 7nm Vega GPU. Dubbed the Radeon Instinct MI60 and Radeon Instinct MI50, the two cards are aimed squarely at the enterprise accelerator market, with AMD looking to significantly improve their performance competitiveness in everything from HPC to machine learning.

Both cards are based on AMD’s 7nm GPU, which although we’ve known about at a high level for some time now, we’re only finally getting some more details on. GPU is based on a refined version of AMD’s existing Vega architecture, essentially adding compute-focused features to the chip that are necessary for the accelerator market. Interestingly, in terms of functional blocks here, 7nm Vega is actually rather close to the existing 14nm “Vega 10” GPU: both feature 64 CUs and HBM2. The difference comes down to these extra accelerator features, and the die size itself.

With respect to accelerator features, 7nm Vega and the resulting MI60 & MI50 cards differentiates itself from the previous Vega 10-powered MI25 in a few key areas. 7nm Vega brings support for half-rate double precision – up from 1/16th rate – and AMD is supporting new low precision data types as well. These INT8 and INT4 instructions are especially useful for machine learning inferencing, where high precision isn’t necessary, with AMD able to get up to 4x the perf of an FP16/INT16 data type when using the smallest INT4 data type. However it’s not clear from AMD’s presentation how flexible these new data types are – and with what instructions they can be used – which will be important for understanding the full capabilities of the new GPU. All told, AMD is claiming a peak throughput of 7.4 TFLOPS FP64, 14.7 TFLOPS FP32, and 118 TOPS for INT4.

7nm Vega also buffs up AMD’s memory capabilities. The GPU adds another pair of HBM2 memory controllers, giving it 4 in total. Combined with a modest increase in memory clockspeeds to 2Gbps, and AMD now has a full 1TB/sec of memory bandwidth in the GPU’s fastest configuration. This is even more than NVIDIA’s flagship GV100 GPU, giving AMD the edge in bandwidth. Meanwhile as this is an enterprise-focused GPU, it offers end-to-end ECC, marking the first AMD GPU to offer complete ECC support in several years.

The enterprise flourishes also apply to 7nm Vega’s I/O options. On the PCIe front, AMD has revealed that the GPU supports the recently finalized PCIe 4 standard, which doubles the amount of memory bandwidth per x16 slot to 31.5GB/sec. However AMD isn’t stopping there. The new GPU also includes a pair of off-chip Infinity Fabric links, allowing for the Radeon Instinct cards to be directly connected to each other via the coherent links. I’m still waiting for a confirmed breakdown on the numbers, but it looks like each link supports 50GB/sec down and 50GB/sec up in bandwidth.

Notably, since there are only 2 links per GPU, AMD’s topology options will be limited to variations on rings. So GPUs in 4-way configurations won’t all be able to directly address each other. Meanwhile AMD is still sticking with PCIe cards as their base form factor here – no custom mezzanine-style cards like NVIDIA – so the cards are connected via a bridge on the top. Meanwhile backhaul to the CPU (AMD suggests an Epyc, of course) is handled over PCIe 4.

Finally, looking at the GPU itself, it’s interesting to note just how small it is. Because AMD didn’t significantly bulk up the GPU on CUs, thanks to the 7nm process the new GPU is actually a good bit smaller than the original 484mm2 Vega 10 GPU. The new GPU comes in at 331mm2, packing in 13.2B transistors. Though it should be noted that AMD’s performance estimates are realistically conservative here; while 7nm does bring power consumption down, AMD is still only touting >1.25x performance of MI25 at the same power consumption. The true power in the new cards lies in their new features, rather than standard FP16/FP32 calculations that the existing MI25 card was already geared for.

Wrapping things up, Radeon Instinct MI60 will be shipping in Q4 of this year. AMD has not announced a price, but as a cutting-edge 7nm GPU, don’t expect it to be cheap. MI60 will then be followed by MI50 in Q1 of next year, giving AMD’s customers a second, cheaper option to access 7nm Vega.

          Comment on The Jewish Nurse by Jack5      Cache   Translate Page      
Jewish researchers have won Nobel prizes greatly out of proportion to the world's Jewish population, but it's a step too far to say, as Inandout does, that "Jews invent most of the day to day technology we take for granted." William Shockley led the team of three which developed the transistor, probably the most important invention of the 20th century. Most of our electronic gizmos stem from this technology. Shockley went on to become a champion of eugenics, an extremist who is a hero of many far right-wing outsiders. Judaism fosters development of intellectuals, and in my view New Zealand would have benefited greatly if we had taken in far, far more Jewish refugees in the 1930s. Depending on your views, that would have been by stimulating the national intellectual level and education, or, by lifting the IQ of the NZ gene pool. But technologists aren't designated by their race, their religion, or their politics. You just have to consider some of the achievements of Nazi Germany in World War 2. One example is the rocket knowledge which later gave both West and East blocs their starts in space technology.

I dispositivi possono poi contare sulla nuova Huawei SuperCharge da 40W e sulla carica rapida wireless Huawei da 15W, le quali funzionano in sincronia per garantire agli utenti una durata della batteria molto più elevata. Realizzata in collaborazione con Leica, la nuova tripla fotocamera con grandangolo offre una visione più ampia e dettagli straordinari per restituire scatti in modalità macro con una resa decisamente maggiore per oggetti a distanza di soli 2.5cm dall’obiettivo. Inoltre, l’Hyper Optical Pattern utilizzato sul retro gioca con la luce e le ombre, producendo un effetto ottico iridescente e accattivante. Infine, la fotocamera è disposta all’interno di un design a matrice 2 per 2 per donargli un’identità visiva riconoscibile anche a distanza. Per quanto riguarda il sistema operativo, la serie Mate 20 fa affidamento sull’interfaccia EMUI 9.0 basata su Android 9 Pie, potendo quindi contare su algoritmi di autoapprendimento AI, un sistema di allocazione delle risorse integrato e modulare, e un ambiente Android altamente ottimizzato. Disponibile in 6,53 pollici, 6,39 pollici e 7,2 pollici, la serie comprende ben quattro modelli: Huawie Mate 20, Huawei Mate 20 Pro, Huawei Mate 20 X e Porsche Design Huawei Mate 20 RS. Entrando nel dettaglio, il SoC raggruppa 6,9 miliardi di transistor all’interno di una matrice delle dimensioni di un’unghia. Rispetto a Kirin 970, quest’ultimo chipset è equipaggiato con una CPU più potente del 75%, una GPU più potente del 46% e una NPU più potente del 226%. Inoltre, la CPU è più efficiente del 58%, la GPU è più efficiente del 178%, mentre la NPU raggiunge un’efficienza più alta del 182%. Huawei ha poi progettato un’architettura a tre livelli composta da due core ultra-large, due large core e quattro small core, garantendo così alla CPU la flessibilità di allocare la quantità ottimale di risorse a compiti pesanti, medi e leggeri per livelli di efficienza senza precedenti, migliorando le prestazioni del SoC e la durata della batteria. Il Mate 20 Pro supporta la tecnologia 4.5G LTE Cat.21 standard, consentendo agli utenti di usufruire di velocità di download fino a 1,4 Gbps. I dispositivi di alta gamma supportano anche la tecnologia di posizionamento GPS dual-band (L1 + L5). La tecnologia AI GPS Satellite Selection migliora la precisione di posizionamento tra un’ampia gamma di scenari. Huawei Mate 20 Pro vanta poi una batteria ad alta densità da 4200 mAh e supporta 40 Huawei SuperCharge, che fornisce al dispositivo una carica del 70% in 30 minuti. La sicurezza della tecnologia è certificata da TÜV Rheinland. Inoltre, Huawei Mate 20 Pro supporta la carica rapida wireless Huawei da 15W, e la tecnologia wireless Reverse Charging che consente al dispositivo di funzionare come un power bank per selezionati dispositivi elettronici che supportano la ricarica wireless. Per finire, Huawei Mate 20 X ha una batteria da 5000 mAh ed è dotato di un sistema che utilizza grafene e camera di vapore per offrire prestazioni di raffreddamento eccezionali. Con il sistema di raffreddamento in atto, la CPU e la GPU incorporate in Huawei Mate 20 X possono rimanere a pieno regime per un lungo periodo di tempo e offrire ai consumatori un’esperienza di gioco più fluida e soddisfacente. Il sistema super cool di Huawei segna anche la prima volta che il grafene viene utilizzato per raffreddare gli smartphone. Per quanto riguarda la fotocamera, quella a disposizione del Mate 20 Pro è dotata di un obiettivo principale da 40 megapixel, una fotocamera ultra grandangolare da 20 megapixel e una fotocamera teleobiettivo da 8 megapixel. Insieme, il trio di obiettivi supporta un’ampia gamma di lunghezze focali (equivalenti alle prestazioni di un obiettivo zoom 16-270 mm), che consente di assicurare i risultati delle fotocamere professionali. La serie Mate 20 dispone anche di una AI Portrait Color per i video. Usando l’intelligenza artificiale, la serie Mate 20 può isolare i soggetti umani e desaturare i colori che li circondano per evidenziare la persona. AI Spotlight Reel identifica le clip con un tema condiviso e genera automaticamente un montaggio, realizzato interamente con evidenziazioni. Chiudiamo segnalando che Huawei Mate 20 e Mate 20 Pro sono già disponibili in Italia al prezzo consigliato rispettivamente di € 799 e € 1099. Scarica questa pagina in formato PDF

On the Bipolar DC Flow Field-Effect-Transistor for Multifunctional Sample Handing in Microfluidics: A Theoretical Analysis under the Debye⁻Huckel Limit.

Micromachines (Basel). 2018 Feb 16;9(2):

Authors: Liu W, Wu Q, Ren Y, Cui P, Yao B, Li Y, Hui M, Jiang T, Bai L

Abstract
We present herein a novel method of bipolar field-effect control on DC electroosmosis (DCEO) from a physical point of view, in the context of an intelligent and robust operation tool for stratified laminar streams in microscale systems. In this unique design of the DC flow field-effect-transistor (DC-FFET), a pair of face-to-face external gate terminals are imposed with opposite gate-voltage polarities. Diffuse-charge dynamics induces heteropolar Debye screening charge within the diffuse double layer adjacent to the face-to-face oppositely-polarized gates, respectively. A background electric field is applied across the source-drain terminal and forces the face-to-face counterionic charge of reversed polarities into induced-charge electroosmotic (ICEO) vortex flow in the lateral direction. The chaotic turbulence of the transverse ICEO whirlpool interacts actively with the conventional plug flow of DCEO, giving rise to twisted streamlines for simultaneous DCEO pumping and ICEO mixing of fluid samples along the channel length direction. A mathematical model in thin-layer approximation and the low-voltage limit is subsequently established to test the feasibility of the bipolar DC-FFET configuration in electrokinetic manipulation of fluids at the micrometer dimension. According to our simulation analysis, an integrated device design with two sets of side-by-side, but upside-down gate electrode pair exhibits outstanding performance in electroconvective pumping and mixing even without any externally-applied pressure difference. Moreover, a paradigm of a microdevice for fully electrokinetics-driven analyte treatment is established with an array of reversed bipolar gate-terminal pairs arranged on top of the dielectric membrane along the channel length direction, from which we can obtain almost a perfect liquid mixture by using a smaller magnitude of gate voltages for causing less detrimental effects at a small Dukhin number. Sustained by theoretical analysis, our physical demonstration on bipolar field-effect flow control for the microfluidic device of dual functionalities in simultaneous electroconvective pumping and mixing holds great potential in the development of fully-automated liquid-phase actuators in modern microfluidic systems.

          Elektryczny Harley-Davidson LiveWire 2020 w przyszłym roku! Europejska premiera za nami      Cache   Translate Page      

Podczas konferencji prasowej na targach EICMA w Mediolanie europejską premierę miał nowy, elektryczny motocykl Harley-Davidson® LiveWire™. Marc McAllister, wiceprezes ds. planowania produktu i oferty, podał długo wyczekiwane specyfikacje i szczegóły pierwszego w ofercie Harley-Davidson elektrycznego dwukołowca. 

Motocykl LiveWire, zaprezentowany na targach jako model produkcyjny, zostanie wprowadzony na rynek w 2019 roku w ramach strategii budowania pojazdów nowej generacji dla nowych generacji motocyklistów. W ramach swojego planu Harley-Davidson  zamierza stać się światowym liderem w produkcji elektrycznych motocykli, zdecydowanie lecz rozsądnie inwestując w technologie pojazdów o napędzie elektrycznym. Firma planuje wprowadzić pełną ofertę tych pojazdów do 2022 roku.

Wizja stanowiąca podstawę motocykla LiveWire pojawiła się wraz z motocyklem Project LiveWire, pokazanym jako prototyp w 2014 roku mający na celu sprawdzić potencjał motocykli zasilanych prądem.

Czerpiąc z doświadczeń uzyskanych podczas jazd demonstracyjnych Project LiveWire oraz po zrealizowaniu programu intensywnego rozwoju, model Harley-Davidson LiveWire oferuje kierowcy całkiem nowe doznania podczas jazdy motocyklem. Dzięki natychmiastowemu dostępowi do wysokiego momentu obrotowego elektryczny motocykl LiveWire może osiągnąć niesamowite przyspieszenie za jednym ruchem przepustnicy, bez zmiany biegów i bez użycia sprzęgła. A nisko położony środek ciężkości, sztywna aluminiowa rama i najwyższej jakości regulowane zawieszenie pozwalają na bardzo dynamiczną jazdę. Wydajność i zasięg są optymalne dla kierowcy przemierzającego na motocyklu ulice miasta.

LiveWire – zasilanie

Motocykl LiveWire zasilany jest silnikiem elektrycznym z magnesami trwałymi, wytwarzającym moment obrotowy w chwili poruszenia przepustnicą, co umożliwia rewelacyjne przyspieszenie. Silnik jest umieszczony nisko, aby obniżyć ośrodek ciężkości i zapewnić dynamikę jazdy motocykla niezależnie od jego prędkości oraz zagwarantować kontrolę przy hamowaniu. Model LiveWire wytwarza dźwięk, którego wysokość i głośność zmienia się wraz ze zmianą prędkości – to nowy dźwięk, charakterystyczny dla elektrycznego motocykla LiveWire.

Harley-Davidson LiveWire – podwozie

Maksymalizację parametrów układu napędowego zapewnia podwozie zaprojektowane tak, aby zapewnić zwinność i pełną kontrolę pojazdu w ruchu miejskim oraz ekscytującą jazdę i przyczepność na zakrętach mniej uczęszczanych ulic. Motocykl LiveWire jest wyposażony w nowoczesne, regulowane zawieszenie Showa®. Tylny amortyzator Showa® BFRC-lite® (Balanced Free Rear Cushion-lite) współpracuje z przednim amortyzatorem Showa SFF-BP® (Separate Function Fork-Big Piston®). Konstrukcja jest zrównoważona tak, aby idealnie wpasować się w parametry tylnego amortyzatora oraz zapewnić wyjątkową kontrolę przechyłów przy niskiej prędkości.

Aby zapewnić jeszcze lepszą kontrolę i podnieść parametry motocykla, LiveWire jest wyposażony w hamulce z zaciskami Brembo typu Monoblock i tarczami o średnicy 300 m, dzięki czemu można w pełni korzystać z mocy motocykla przy gwarancji pewnego hamowania. Bezpieczeństwo podczas jazdy zapewniają także stanowiące standardowe wyposażenie motocykla system hamowania ABS i system kontroli trakcji (TCS) oraz opony H-D/Michelin Scorcher (180mm tył/120mm przód). Aby odpowiednio dostosować parametry motocykla, użytkownik LiveWire ma możliwość wyboru jednego z siedmiu trybów jazdy, z których cztery to standardowe ustawienia fabryczne, a trzy może skalibrować sam użytkownik. 

Technika w LiveWire

Kolorowy ekran dotykowy TFT (thin-film-transistor, rodzaj ciekłokrystalicznego wyświetlacza cechującego się wysoką jakością obrazu i kontrastu) znajdujący się powyżej kierownicy wyświetla informacje w sposób jasny i czytelny. Element ten można przechylać, co pozwala ustawić ekran pod optymalnym kątem. System multimedialny umożliwia kierowcy korzystanie z Bluetooth, nawigacji, słuchanie muzyki i wykorzystanie innych funkcji.

Motocykl LiveWire jest wyposażony w akumulator typu RESS (układ magazynowania energii wielokrotnego ładowania lub główny akumulator) złożony z [...]

          Let's talk jitter.      Cache   Translate Page      
When I was a young teenager I read old copies of that magazine, Radio, Television & Hobbies. I continued to read it when it changed name to Electronics Australia. Hi-fi was evolving from mono to stereo and from valves to transistors. Open reel tape recorders were in use to make home recordings. They were simpler times! The construction projects were very useful for developing an understanding, even if all you did was to read the well worded explanations of how the different parts of the circuits worked, such as the various stages of a superhet radio. One of the consequences of the move to integrated circuits and later to large scale integrated circuits was that generally became uneconomic to build your own circuits using discrete components rather than ICs. You could still do it though, for the fun and the learning experience! As for clock jitter it could be fun to induce it, at increasing levels, in a circuit one had wired up at home, until it became audible. However these days, I think I'd be more inclined to do that in software, arriving at files along the lines of the test files referred to earlier by Eggcup:

          Help with wire feed on S22-A      Cache   Translate Page      
I had an issue with my wire feeder a few weeks ago. I went to use it and when I pulled the trigger nothing happened then I saw a little bit of smoke coming out of the feeder. I blew a transistor. No big deal, ordered a new one, put it in and hooked the board back up and was up and running. Well...
          multiple instances for monte carlo      Cache   Translate Page      

Hi,

I design a small block with a few transistors.

I want to see and measure, in my simulations, 1000 instances of this block, as they will be fabricated in Si (i.e. no intentional extreme cases, but true distribution).

For various reasons, I prefer not to run 1000 different splits, but instead to instantiate the small block 10 times in my testbench and run only 100 splits.

This way, instead of one measurement, I have 10 measurements in my Maestro, and I extract the required statistics manually based on the 100X10=1000 measurement results I have.

The question is, is my thinking correct. 

I'm afraid that for some reason, due to the way the Monte Carlo in implemented, I don't really have results of 1000 blocks, as the 10 different instances may be correlated somehow. 

If it matters, the sampling method I'm using is "random", because I want to see a true distribution of 1000 blocks and not to see extreme end cases.

Thanks!
