Corandom
Use Corandom 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).
