OpenMP and QPAR MFLOPS Benchmarks - The benchmarks carry out the same calculations as MP MFLOPS Benchmark, essentially using the same code, without any OpenMP code requirements, but with critical loops preceded by a simple “go parallel” directive. QPAR is a Microsoft alternative to OpenMP. With the results shown, OpenMP maximum speeds of 24 GFLOPS are demonstrated via Windows and 91 GFLOPS using QPAR. Linux results show 23 GFLOPS for 32 bit compilations, with 50 GFLOPS at 64 bits, improving to 94 GFLOPS with an AVX compile option.

Linux Versions - whetsMP32, whetsMP32DP, whetsMP64 and whetsMP64DP can be downloaded in linux_multithreading_apps.tar.gz , along with source code. Further details can be found in linux multithreading benchmarks.htm. This multithreading benchmark also has a run time parameter to specify the number of threads (up to 64) with a default identified as configured CPUs in gathered system information.

The first results below are for Version 1, single thread, 64 bit and 32 bit, with performance similar to the Windows versions, that is faster integer MB/second via caches at 64 bits. The other results are for 64 bit Version 2, where performance is quite similar to the Windows (Version 1) speeds. {Ignore 6 KB speeds - needs a longer test] The last two columns are for Linux Version 1 results, where RAM speeds are shown to be faster than the 51.2 GB/second specification, due to caching effects. In Version 2, each thread reads all the data but at staggered starting points and additional RAM is read, to prove the point. Now a maximum of 40.6 GB/second is shown, at 4 threads, 2.2 times faster than that with one thread.

The Linux benchmark has additional Mutex tests that restrict updating access to one thread at a time. The effect appears to produce some faster speeds with cached data but slower from RAM. With the other procedures, multithreading performance gains and losses are different between the Windows and Linux compilations.

Maximum SSE MFLOPS per core are equal to CPU MHz x 4 (128 bit SSE register width) x 2 (linked multiply and add) or 31.2 GFLOPS for the Core i7 considered here, giving 124.8 GFLOPS for four cores. The 256 bit AVX registers double this score. Both Windows and Linux programs demonstrated respectable performance of more than 90 GFLOPS for SSE and the Linux Benchmark near 180 GFLOPS using AVX instructions.
