Introduction
This test determines if the proper environment has been established.
Test steps
Submit a test job and the issue a hold on the job.
|
> qsub -c enabled test.sh 999.xxx.yyy > qhold 999 |
Possible failures
Normally the result of qhold is nothing. If an error message is produced saying that qhold is not a supported feature then one of the following configuration errors might be present.
Successful results
If no configuration was done to specify a specific directory location for the checkpoint file, the default location is off of the TORQUE directory, which in my case is /var/spool/torque/checkpoint.
Otherwise, go to the specified directory for the checkpoint image files. This was done by either specifying an option on job submission, i.e. -c dir=/home/test or by setting an attribute on the execution quere. This is done with the command qmgr -c 'set queue batch checkpoint_dir=/home/test'.
Doing a directory listing shows the following.

# find /var/spool/torque/checkpoint /var/spool/torque/checkpoint /var/spool/torque/checkpoint/999.xxx.yyy.CK /var/spool/torque/checkpoint/999.xxx.yyy.CK/ckpt.999.xxx.yyy.1205266630 # find /var/spool/torque/checkpoint |xargs ls -l -r-------- 1 root root 543779 2008-03-11 14:17 /var/spool/torque/checkpoint/999.xxx.yyy.CK/ckpt.999.xxx.yyy.1205266630

Doing a qstat -f command should show the job in a held state, job_state = H. Note that the attribute checkpoint_name is set to the name of the file seen above.
If a checkpoint directory has been specified, there will also be an attribute checkpoint_dir in the output of qstat -f.
