C_ACTION_shared

Intel® MPI Benchmarks User Guide and Methodology Description

# C_[ACTION]_shared

The benchmark of a collective access from all processes to a common file, with a shared file pointer.

This benchmark is based on the following MPI routines:

- `MPI_File_read_ordered/MPI_File_write_ordered` for the blocking mode

- `MPI_File_.._ordered_begin/MPI_File_.._ordered_end` for the nonblocking mode

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