IntelĀ® MPI Benchmarks User Guide and Methodology Description
The benchmark for the MPI_File_open/MPI_File_close functions. All processes open the same file. To avoid MPI implementation optimizations for an unused file, a negligible non-trivial action is performed with the file. See the basic definitions of the benchmark below.
