PBS: job killed: cput 279480 exceeded limit 270000

My program allocates 224 cores, and CPU limit is 270000, so 270000/224=1205 seconds. So, for a large graph, after it has run 1205 seconds, PBS will kill the task. Is it possible to have more CPU?

Hi,

 

Thank you for posting in Intel Communities.

 

Intel DevCloud for oneAPI nodes have a default CPU time limit of 75 hours (270000 seconds). This time can be extended up to 100 hours using the following parameter while requesting for the node:

$ qsub […] -l walltime=24:00:00 -l cput=100:00:00

Eg:

$ qsub -I -l nodes=1:ppn=2 -l walltime=24:00:00 -l cput=100:00:00

Hello,

Thank you for the help! I submitted a job so waiting for the output to see if it works.

I was able to find this solution earlier, but there was not much explanation. It seems to be working from qstat output as it seems to use CPU from two nodes. I wanted to know how accurate this is?

#PBS -l select=4:ncpus=56

Hi,

 

Sorry, for the delay in getting back to you. 

PBS directory commands in Intel DevCloud for oneAPI allows you to choose upto 2 nodes but will still have the walltime and CPU time limit.

The PBS command you have used (#PBS -l select=4:ncpus=56) is not accurate since you can access only upto 2 nodes. 

For reference:

If you need any additional information, please let us know.

 

Regards,

Sreedevi

Hi SreedeviK,

 

Your solution did help and gave possibility to have more CPU time. It is still not enough for my research analysis but it does allow to create less jobs. I do understand that this is a free resource. Sorry for the late reply I was not able to login to this portal for some reason.
