Nvidia Releases Next-Generation Tesla GPU Accelerators
The new K80 offers twice the performance and memory bandwidth of the current K40, and is being leveraged by HP, Dell and other system makers.Nvidia is rolling out the Tesla K80, next generation of its GPU accelerators that offers almost twice the performance and memory bandwidth of its predecessor, which was released only a year ago. The K80, announced Nov. 17 at the SC14 supercomputing show in New Orleans, becomes the flagship product for Nvidia's Tesla Accelerated Computing Platform, which offers hardware, software and an accompanying ecosystem for accelerated applications in the data center. High-performance computing (HPC) organizations are increasingly turning to accelerators—both GPUs from Nvidia and Advanced Micro Devices and x86 co-processors from Intel—to boost the performance of their systems while keeping a lid on power consumption and operating costs. Sixty-two of the 500 fastest supercomputers in the world—according to the Top500 list released in June—used accelerators or co-processors, up from 53 on the November 2013 list. Forty-four of those systems used Nvidia GPUs, with 17 running Intel's x86-based Xeon Phi co-processors. Two used ATI Radeon GPUs from AMD. Those numbers will change when the latest list is released at the supercomputer show this week.
According to Sumit Gupta, general manager of Tesla accelerated computing at Nvidia, the K80—with 4,992 CUDA parallel processing cores—runs complex and computationally-intensive scientific applications 10 times faster than CPUs. Running such applications on systems with CPUs alone, without accelerators, at the same rate of performance would require supercomputers that are significantly larger, more expensive and less power efficient, Gupta told eWEEK.
