[slurm-dev] Job Accounting for sstat

[Lachlan Musicman]

Hi,

I noticed that sstat wasn't giving any data, so I looked into how to make that happen.

After some reading, I cracked open slurm.conf and uncommented these two lines:

JobAcctGatherFrequency=30
JobAcctGatherType=jobacct_gather/linux

after confirming that jobacct_gather_linux.so was in PluginDir.

But I am still getting no data. So I went to read some more and noticed that the slurm.conf docs suggest that the format for Frequency is this:

JobAcctGatherFrequency=<datatype>=<interval>

Whereas on the jobacct_gather plugin page (http://slurm.schedmd.com/jobacct_gatherplugins.html), it states:

JobAcctGatherFrequency

Time interval between pollings in seconds.

1. Is adding the task= the only thing I'm missing, or do I need to do something else?
2. Does JobAcctGatherFrequency=30 have an implied task=, or is this an error in the default slurm.conf ?

Cheers

L.

Also anything you wan to track with sstat has to be launched via srun,
otherwise the information is only recorded in slurmdbd when it completes.

cheers!

Oh! Thanks.

I presume that includes sruns that are in an sbatch file.

Yup, that's right.

Ok, I know it's a late reply, but I still see no results in sstat when using srun within an sbatch file.

ie

$ sbatch my.sbatch

where my.sbatch is

#!/bin/bash
 
#SBATCH --nodes=1
#SBATCH --ntasks=8
#SBATCH --job-name="QOS_TEST"

srun -n 1 /home/lachlan.simpson/tmp/runjob.sh

I get nothing in sstat.

If I run:

$ srun runjob.sh

I get sstat results.

Is it because runjob.sh opens with #!/bin/bash?
