GPUs Using NVIDIA GPUDirect
GPU-Equipped Clusters From NVIDIA, Coupled With QLogic
TrueScale InfiniBand Fabric, Achieve New Levels of
Computational and Message Passing Performance
ALISO VIEJO, Calif., May 31, 2010 (GLOBE NEWSWIRE) -- QLogic Corp.
(Nasdaq:QLGC) today announced that it is working closely with NVIDIA to
optimize performance of NVIDIA Tesla GPUs in multi-node configurations
interconnected with QLogic(R) TrueScale(TM) InfiniBand(R) fabrics. By
tapping into the new NVIDIA GPUDirect(TM) technology, QLogic InfiniBand
adapters, switches and directors communicate directly with NVIDIA GPUs
with reduced CPU involvement, reducing communication overhead for
optimal results.
"HPC environments increasingly deploy multiple nodes with NVIDIA GPUs
to speed up processing for computationally-intensive applications such
as seismic processing and molecular dynamics modeling," said Andy
Keane, general manager, Tesla business at NVIDIA. "QLogic's TrueScale
InfiniBand architecture, optimized with our GPUDirect technology,
natively supports this distributed computing environment with fully
optimized NVIDIA-based GPU performance and industry-leading message
passing performance."
QLogic's TrueScale InfiniBand architecture requires no application
re-compilation or software patches to deliver computational performance
with NVIDIA GPUs, and still maintain the industry-leading scalable
latency and high message rate for which QLogic InfiniBand solutions are
known.
"Our work with NVIDIA is another demonstration of how QLogic TrueScale
InfiniBand goes beyond basic OpenFabrics implementations to fully
optimize the performance of key cluster technologies," said Jesse
Parker, vice president and general manager, Network Solutions Group,
QLogic. "Our software development groups continually strive to
anticipate and meet the needs of HPC users who are implementing the
latest technologies to maximize application performance, and our
support of NVIDIA and its innovative GPUDirect technology is a great
example of how those efforts benefit customers."
