Nvidia said a new supercomputer built in China is the world's
fastest and is powered by over 7,000 of its graphics processor units.
Tianhe-1A, a new supercomputer revealed today at HPC 2010 China, has set a
new performance record of 2.507 petaflops, as measured by the LINPACK
benchmark, making it the fastest system in China and in the world today,
Nvidia said.
Tianhe-1A is coupling parallel GPUs with multi-core CPUs, enabling
significant achievements in performance, size and power. The system uses
7,168 NVIDIA Tesla M2050 GPUs and 14,336 CPUs; it would require more than
50,000 CPUs and twice as much floor space to deliver the same performance
using CPUs alone.
More importantly, a 2.507 petaflop system built entirely with CPUs would
consume more than 12 megawatts. Thanks to the use of GPUs in a
heterogeneous computing environment, Tianhe-1A consumes only 4.04
megawatts, making it 3 times more power efficient -- the difference in
power consumption is enough to provide electricity to over 5000 homes for
a year.
Tianhe-1A was designed by the National University of Defense Technology
(NUDT) in China. The system is housed at National Supercomputer Center in
Tianjin and is already fully operational.
"The performance and efficiency of Tianhe-1A was simply not possible
without GPUs," said Guangming Liu, chief of National Supercomputer Center
in Tianjin. "The scientific research that is now possible with a system of
this scale is almost without limits; we could not be more pleased with the
results."
The Tianhe-1A supercomputer will be operated as an open access system to
use for large scale scientific computations.
"GPUs are redefining high performance computing," said Jen-Hsun Huang,
president and CEO of NVIDIA. "With the Tianhe-1A, GPUs now power two of
the top three fastest computers in the world today. These GPU
supercomputers are essential tools for scientists looking to turbocharge
their rate of discovery."
NVIDIA Tesla GPUs, based on the CUDA parallel computing architecture, are
designed specifically for high performance computing (HPC) environments
and deliver transformative performance increases across a wide range of
HPC fields, including drug discovery, hurricane and tsunami modeling,
cancer research, car design, even studying the formation of galaxies. |
