Display used CPU hours with slurm

Question

I have a user account on a super computer where jobs are handled with slurm.

I would like to know the total amount of CPU hours that I have consumed on this super computer. I think that's an understandable question, because there is only a limited number of CPU hours available per project. I'm surprised that an answer is not easy to find.

I know that there are all these commands like sacct, sreport, sshare, etc... but it seems that there is no simple command that displays the used CPU hours.

Can someone help me out?

Answer 1

As others have commented, sacct should give you that information. You will need to look at the man page to get information for past jobs. You can specify a --starttime and --endtime to restrict your query to match your allocation as it ends/renews. The -l options should get you more information than you need so you can get a smaller set of options by specifying what you need with --format.

In your instance, the correct answer is to ask the administrators. You have been given an allocation of time to draw from. They likely have a system that will show you your balance and you can reconcile your balance against the output of sacct. Also, if the system you are using has different node types such as high memory, GPU, MIC, or old, they will likely charge you differently for those resources.
