This benchmark tests the MPI_Put operation using one active process that transfers data to all other processes. All target processes are waiting in the MPI_Barrier call while the origin process performs the transfers.

Property

Description

Measured pattern

(N*MPI_Put)/MPI_Win_flush_all, where N is the number of target processes

MPI data type

MPI_BYTE (origin and target)

Reported timings

Bare time

Reported throughput

MBps
