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
