Quadrics QsNetII Interconnect

• qsnet2_level_test level2
• qsnet2_level_test level3
If the cluster is a federated configuration (more than 128 nodes), the
qsnet2_drain_test script also runs the following tests:
• /usr/bin/qsportmap.
• qsnet2_level_test level4.
_________________________ Note _________________________
Clusters might be configured with full bandwidth or reduced bandwidth,
as defined in the configuration rules and cabling tables for your cluster.
If your cluster has a reduced bandwidth you must also apply the test
constraints defined in Section 12.11.
If your cluster has more than 256 nodes, you can run qsnet2_level_test
level5 when the qsnet2_drain_test script completes.
The qsnetsoak command is an alternative to the qsnet2_level_test provided
that the database and the swmlogger utility are fully configured and proven to be
working reliably.
_________________________ Note _________________________
Ensure that you have tested the database and the swmlogger utility
before using the qsnetsoak command as a drain test. Otherwise, error
reports are not logged and the test might falsely pass with no errors.
The command syntax is as follows:
# srun -p lsf -n nn /usr/bin/qsnetsoak
Where nn identifies the maximum number of processors on the system.
The following example shows typical output from the qsnet2_drain_test script:
root@xc4n16 log]# srun -p lsf -n 10 /usr/bin/qsnetsoak
