Comment GPU to network (Score 1) 175

I wonder when a GPU will be able to directly access a network of some sort. Right now, you would need glue code on the CPU to link multiple GPUs in different systems together. I imagine that some HPC applications would run quite well with 100 GPUs spread over 25-50 machines with a QDR InfiniBand link between them.

Comment what is the interconnect (Score 1) 1

I wonder what the interconnect will be? An earlier Riken system uses lots and lots of 4X SDR InfiniBand (10gbps) . They used lots of 32 port IB switches from InfiniCon Systems (I worked there at the time). Now IB is up to 12X SDR (30 dbps) 4X QDR (40 gbps). I wonder what IB company will get the deal. InfiniCon become SilverStorm and is now owned by QLogic. There are also Mellanox, Voltaire, and Sun.


Submission + - What Britney Spears Can Reveal About Alzheimer's

Hugh Pickens writes: "Time Magazine reports that researchers at the Cleveland Clinic report that they may have found a way to identify those most at risk of developing Alzheimer's long before symptoms develop — simply by asking them whether they recognize celebrities such as Britney Spears and Johnny Carson. It turns out that when people who are at highest risk of Alzheimer's try to recognize a famous name, their brains activate in very different ways from those of people who aren't at risk and scientists can actually see this difference using functional magnetic resonance imaging, or fMRI. A team led by Stephen Rao, a brain-imaging specialist, found that those who were at the highest risk of developing Alzheimer's showed high levels of activity in the hippocampus, posterior cingulate and regions of the frontal cortex, all areas involved in memory. "This pushes the envelope further in attempting to detect dysfunction in the brain at a stage earlier than any detectable clinical measurement of cognitive decline," says Dr. Ralph Nixon. The idea is not necessarily to diagnose Alzheimer's earlier but to help identify those most vulnerable to cognitive decline so they can participate in clinical trials of new drugs designed to postpone or reduce symptoms. "If we can delay the onset of Alzheimer's by five years," says Rao, "by some estimates we can cut the incidence of Alzheimer's in half. If we can delay the disease by 10 years, we could almost eliminate it because people would die from other conditions first.""

Submission + - Nvidia predicts 570x GPU performance boost (

Gianna Borgnine writes: "Nvidia is predicting that GPU performance is going to increase a whopping 570-fold in the next six years. According to TG Daily, Nvidia CEO Jen-Hsun Huang made the prediction at this year's Hot Chips symposium. Huang claimed that while the performance of GPU silicon is heading for a monumental increase in the next six years — making it 570 times faster than the products available today — CPU technology will find itself lagging behind, increasing to a mere 3 times current performance levels. "Huang also discussed a number of 'real-world' GPU applications, including energy exploration, interactive ray tracing and CGI simulations.""

Submission + - Fujitsu SuperComputer With 10-Petaflop Performance 1

An anonymous reader writes: Fujitsu is currently developing a new supercomputer which will be able to achieve 10-petaflop performance — ten times faster than today's most powerful supercomputer. The new system configuration with a scalar processing architecture makes use of the world's fastest CPU (Fujitsu SPARC64 VIIIfx with 8 cores, 128 gigaflops), and will be unveiled by 2012.

Submission + - Holiday shipping statistics

Meostro writes: It may seem that your house has become a shipping hub for the past few days, with holiday goodies being delivered daily or even several times a day. However, what you see is infinitesimal versus the actual volume of stuff that goes through the major shipping and logistics networks daily. UPS, FedEx and DHL all have holiday statistics available, and they're impressive.

For example, the FedEx website will see double their average number of tracking requests, at nearly 6 million per day during the month of December. UPS will deliver about 243 packages every second (for a full 24 hours) on their peak day, December 20th.

Submission + - FCC won't release cell carrier reliability data

imuffin writes: MSNBC is reporting that the FCC has been collecting data on the reliability of different cell phone carriers in the US. This data could be invaluable to consumers trying to choose a company to sign a lengthy contract with, but the FCC won't release the data to consumers, citing national security risks.

From the article:
A federal Freedom of Information Act request for the data, filed in August by, has been rejected by the agency. The stated reasons: Release of the information could help terrorists plan attacks against the United States, and it would harm the companies involved.

Submission + - HP's Bundle Trouble

narramissic writes: A French consumer group has filed 3 lawsuits against HP, saying the company's practice of selling consumer PCs with Windows pre-installed violates a French law that 'prohibits linking the functionality of a product to another product' — not to mention that consumers wind up paying for an unwanted OS. For its part, HP contends that it is not in violation of the law because the OS is integral to the PC. 'The PC without an OS is not a product because it doesn't work,' said Alain Spitzmuller, legal affairs director for HP France. 'We believe the market is for products that work.'

How Skype Punches Holes in Firewalls 215

An anonymous reader writes "Ever wondered, how P2P software like Skype directly exchanges data — despite the fact, that both machines are sitting behind a firewall that only permits outgoing traffic? Read about the hole punching techniques, that make a firewall admin's nightmares come true."
