Corandom

Use this benchmark to measure a coherent message passing between random ranks.

Property

Description

Measured pattern

Coherent random message passing pattern:

It is an MPI balanced application, where each rank does the same amount of work.

MPI routines

MPI_Irecv, MPI_Send, MPI_Wait

MPI data type

MPI_BYTE

The benchmark reports latency (in microseconds), bandwidth (in million bytes per second), and message rate (in messages per second).
