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.
