rauls 1200005VCY Comment (1) Visits (11268)
With the recent publication of the SPEC CPU2006 scores of the POWER7-based p780 server, the IBM Power Systems have regained leadership on both the SPECint 2006 and SPECfp 2006 components of this industry benchmark suite.
In particular , the peak FP score of 71.5 is 20% higher than the previous best result.
One of the key features that have enabled this achievement is the use of automatic parallelization technology on several benchmarks. This not only highlights the advanced compilation and optimization technology in these compilers, but is also an indicator of the performance available on these systems when using parallel programming, for example through OpenMP.
