Unirandom
Use Unirandom to measure a unidirectional message passing between random pairs of ranks.
Property |
Description |
---|---|
Measured pattern |
Unidirectional message passing between random pairs of ranks. Pairs are selected randomly for each message transfer. It is an MPI imbalanced application, where different ranks do different amount of work. |
MPI routines |
MPI_Send, MPI_Recv |
MPI data type |
MPI_BYTE |
The benchmark reports latency (in microseconds), bandwidth (in million bytes per second), and message rate (in messages per second).
