C_ACTION_expl

Intel® MPI Benchmarks User Guide and Methodology Description

# C_[ACTION]_expl

This pattern performs collective access from all processes to a common file, with an explicit file pointer.

This benchmark is based on the following MPI routines:

- `MPI_File_read_at_all/MPI_File_write_at_all` for the blocking mode

- `MPI_File_.._at_all_begin/MPI_File_.._at_all_end` for the nonblocking mode

All other parameters and the measuring method are the same as for the `P_[ACTION]_expl` benchmark.
