Benchmark Information
Competitive and PGI SPEC® OMP2001 results listed below were conducted by The Portland Group on the dates listed. Competitor results were conducted using what The Portland Group believed to be the best known optimization options at the time the results were conducted.
SPEC benchmarks include two fundamental metrics. "Base" performance requires the use of a uniform set of compiler options and runtime settings across all benchmarks in the suite. "Peak" performance allows use of arbitrary combinations of compiler options, runtime settings and profile-feedback optimization to maximize performance of individual benchmarks in the suite. The Portland Group believes Base is most representative of "compile-and-go" performance, and it is for this reason that the comparisons on these pages list 64-bit Base performance only.
The Portland Group uses OMP2001 primarily to compare compiler performance over time. PGI does not perform direct comparative system peformance testing. To minimize performance fluctuations due to hardware variations, PGI retains a limited set of reference systems whose configurations are fixed and stable. As a general rule, reference systems are not modified or upgraded; instead new systems are added and old systems are retired from the reference system pool as needed. The results posted on this web site are organized by individual reference systems.
