Verifying Installation
In order to ensure the InfiniBand network is setup correctly and to check the
connectivity across the cluster, run the HPC Cluster Manager's built-in
Message Passing Interface (MPI) Ping-Pong utility. This test validates the
driver stack, the network protocol, MPI implementation and helps identify
any anomalies in the node-to-node connection.
Under the Diagnostics pane in the HPC Cluster Manager, click
Tests System Performance MPI-Ping-Pong.
NOTE: You can select either or both Lightweight Throughput or Quick Check tests.
Lightweight Throughput test reports the average of the total bandwidth of
the cluster and helps identify slow and fast links across nodes. The Quick
Check test reports the overall latency across the cluster.
