Accelerator test procedure

This is the Cluster Test procedure recommended by HP when your cluster contains nodes with accelerator cards. You should run these accelerator tests and the tests described in “The Cluster Test procedure” (page 29).

Each of these tests use default values. You may change parameters as desired, but be careful the current system limits are not exceeded.

1.Make sure the X server is running and the DISPLAY environment variable is set appropriately.

2.Make sure no one else is running tests on the nodes you will be testing.

3.Run /opt/clustertest/bin/testnodes.pl -gpu on the first head node.
