PGI High Performance Computing Compilers Coming to IBM POWER Systems

SANTA CLARA, CA--(Marketwired - Nov 18, 2014) - NVIDIA (NASDAQ: NVDA) today announced that it is developing an enhanced version of the widely used PGI® optimizing compilers which will allow developers to quickly develop new applications or run Linux x86-based GPU-accelerated applications on IBM POWER CPU systems with minimal effort.

The PGI optimizing Fortran, C and C++ compilers for POWER will provide a user interface, language features, parallel programming features and optimization capabilities that are identical to those available on PGI Linux x86 compilers. 

The new compilers also will support high performance computing (HPC) systems based on the IBM POWER architecture, including the recently announced NVIDIA GPU-accelerated IBM POWER8 systems, and additional systems under development by members of the OpenPOWER Foundation.

"Our goal is to let HPC developers recompile and run their applications on all major CPU and GPU-accelerated platforms with uniformly high performance using a common source code base," said Douglas Miles, director of PGI Compilers & Tools at NVIDIA. "We expect most GPU-accelerated x86 applications currently built with PGI compilers will port to GPU-accelerated POWER systems with a simple re-compile."

The POWER8 CPU is a massively multi-threaded processor, featuring 12 cores each capable of handling eight hardware threads simultaneously. Originally positioned for big data and cloud server applications, the POWER8 architecture is generating strong demand from HPC customers given its many performance-oriented features, such as a high-bandwidth CAPI port (Coherent Accelerator Processor Interface) and future support for the NVLink™ high-speed GPU interconnect.

"Porting and optimizing production HPC applications from one platform to another can be one of the most significant costs in the adoption of breakthrough hardware technologies," said Buddy Bland, project director of the Oak Ridge Leadership Computing Facility at Oak Ridge National Laboratory. "The PGI compiler has been our primary compiler on Jaguar and Titan since 2005. Having the PGI compiler suite available in the POWER environment will provide continuity and facilitate code portability of existing CPU-only and GPU-enabled Titan applications to our next major system."
