Abstract
The Sun FireTM K is the first generation of high-end servers built to the Throughput Computing strategy of Sun Microsystems. The server can scale up to 72 UltraSPARC® IV processors with Chip MultiThreading (CMT) technology, and execute up to 144 threads simultaneously. The Sun StudioTM 9 software includes compilers and tools that provide support for the C, C++, and Fortran OpenMP Version 2.0 specifications, and that fully exploit the capabilities of the UltraSPARC IV processor and the E25K server.
This paper gives an overview of the Sun Fire E25K server and OpenMP support in the Sun Studio 9 software. The paper presents the latest world-class SPEC OMPL benchmark results on the Sun Fire E25K, and compares these results with those on the UltraSPARC III Cu based Sun Fire 15K server.
Results show that base and peak ratios for the SPEC OMPL benchmarks increase by approximately 50% on the Sun Fire E25K server, compared to a Sun Fire 15K server with the same number of processors and with higher clock frequency.
