Intel® MPI Benchmarks User Guide and Methodology Description

# Ialltoall_pure

The benchmark for the`MPI_Ialltoall` function that measures pure communication time. In the case of np number of processes, every process inputs `X*np` bytes (`X` for each process) and receives `X*np` bytes (`X` from each process).

Property | Description
