M.2 Test 1 - Basic operation

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 queue. 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

 

/var/spool/torque/checkpoint:

total 4

drwxr-xr-x 2 root root 4096 2008-03-11 14:17 999.xxx.yyy.CK

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.
