update: Solaris beating Linux Performance
Wednesday Jan 03, 2007
(Update with corrections of previous entry)
Sun Fire X4100/X4200M2 4-thread 2-socket World Record, shows that Solaris 10 and Sun Studio 11 are faster than Opterons running Linux (31% faster than PGI and 8% faster than Pathscale compilers). The Sun Fire X4100/X4200M2 two-way dual-core server produced best SPECompM2001 result of 13222.
Sun Solaris 10/Studio11 was 31% faster than Linux/PGI with AMD Tyan system using SuSE Linux SLES9 SP3 64-bit/PGI 6.2-4. The AMD Tyan even used faster CL4 DIMMs. Both results submitted Nov 2006. The Sun Fire X4100/X4200M2 also topped the IBM p5 520 POWER5+ 1.9GHz AIX5L V5.3 result by 61%.
Solaris/Studio 11 is 8% faster than Linux SuSE SLES9 SP3 64bit using QLogic PathScale Compiler Suite v2.5.
There is a growing body of favorable comparisons showing Solaris advantages over Linux on performance. Remember the previous BM Seer posting on Java performance.
Even more examples of Solaris beating Linux coming soon.

Benchmark Description
The SPEC OMPM2001 Benchmark Suite was released in June 2001 and tests HPC performance using OpenMP for parallelism. It consists of 11 programs (8 in Fortran and 3 in C) parallelized using OpenMP API.
