Benchmarking: OMB MPI (OSU)

Overview

This is a collection of independent MPI message passing performance microbenchmarks developed and written at The Ohio State University. It includes traditional benchmarks and performance measures such as latency, bandwidth and host overhead and can be used for both traditional and GPU-enhanced nodes.
The available test are:

• osu_latency - Ping-pong Latency
• osu_multi_lat - Multi-pair Ping-pong Latency
• osu_bw - Ping-pong Bandwidth
• osu_bibw - Bi-directional BW
• osu_mbw_mr - Throughput or Multiple Bandwidth and Message Rate
• osu_barrier, osu_allreduce, osu_allgather' - Collectives
