IntelĀ® MPI Benchmarks 4.0
C_[ACTION]_indv tests collective access from all processes to a common file, with an individual file pointer. Below see the basic definitions and a schematic view of the pattern.
This benchmark is based on the following MPI routines:
MPI_File_read_all/MPI_File_write_all for the blocking mode
MPI_File_.._all_begin/MPI_File_.._all_end for the nonblocking mode
All other parameters and the measuring method are the same as for the P_[ACTION]_indv benchmark.
