Cray will put Nvidia graphics processors in future large-scale supercomputers, the companies said today.
The announcement follows this summer's jump to the No. 2 spot in global rankings of China's Nvidia-equipped Nebulae supercomputer.
At Nvidia's 2010 GPU Technology Conference today in San Jose, Calif., supercomputer leader Cray announced that it is developing supercomputers that can use Nvidia Tesla 20-Series graphics processing units.
"We're putting this technology--the next generation of Nvidia Tesla--in our large XE6 systems," Barry Bolding, vice president of Cray's products division, said in a phone interview. Cray's largest system, Jaguar, at the Oak Ridge National Laboratory, based on processors from Advanced Micro Devices, is currently ranked No. 1 in the world, according to the Top 500 list.
Cray, which already uses Nvidia GPUs in its low-end desktop supercomputers, is targeting Nvidia's supercomputer-specific Tesla processors for accelerating "modeling code" for scientific applications in its Cray XE6 product line, according to Bolding.
"We're doing this because Nvidia is starting to produce accelerators (GPUs) that are useful to our customers. They've done some enhancements that go beyond a normal graphics accelerator. A couple of years ago, those (Nvidia) GPUs did not have functionality that was appealing to our customers."
Bolding continued. "What we'll see first is the data centers that run a few key applications on the accelerators. The data center that has to run 500 applications? That's the data center that won't move over to accelerators," he said. … Read more
