How Good is Your MPI? Find Out With Graphical Bandwidth and Latency Tests

Microway's MPI Link Checker enabled a cluster user to pinpoint problem nodes in the cluster. By graphically representing the bandwidth and latency of all links in the cluster, a user can see the exact pattern of communication occuring in their cluster. As one underperforming node can slow the performance of an entire MPI job, it is imperative to ensure full speed of all systems.
