OpenMP

OpenMP OpenMP is a relatively new industry standard for shared memory programming. This allows, for the first time, shared memory parallel programs to be made portable across a wide range of platforms. For this reason, UKHEC have identified OpenMP as a key area of current interest. Benchmarks Overheads due to synchronisation and loop scheduling are an important factor in determining the performance of shared memory parallel programs. EPCC have designed a set of microbenchmarks to measure these classes of overhead for language constructs in OpenMP. The benchmarks can be downloaded from the OpenMP Microbenchmarks page. Overheads of OpenMP synchronisation constructs on a 195Mhz SGI Origin 2000, using the MipsPro f90 compiler.
