Property |
Description |
---|---|
Measured pattern |
The ranks are broken into pairs: (0, N/2), (1, N/2 + 1), (2, N/2 + 2) and so on. The number of ranks N must be even. |
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).
IMB-P2P PingPong and IMB-MPI1 PingPong are different benchmarks.
