Dear PDSF Users, today we hold the monthly meeting, slides are posted at: <> We have noticed the requested RAM/job exceeds few times the actual needs(slide 8) and results with the low PDSF utilization (slide 9). The decision was made to reduce the default RAM/job from 4 GB to 2.5 GB in a week from today. Once you know your job needs above 2.5GB of RAM/job I'm suggesting to use the overhead of up to 30%. You can verify how much RAM your completed Slurm job needed by executing one this commands: a) for one job (e.g. 153 MB was needed for jobId=21115): pdsf7 $ sacct --format=job,start,maxrs -j 21115 JobID MaxRSS 2017-12-04T23:47:27 152,584K b) for all jobs run by user=alicesgm since midnight today pdsf7 $ sacct --format=job,start,maxrs -u alicesgm | grep K 5237842.bat+ 2018-06-12T05:54:28 3987488K 5238047.bat+ 2018-06-12T05:55:28 2530456K 5238207.bat+ 2018-06-12T06:15:31 4336212K c) for all jobs run by all STAR user since June 7 pdsf7 $ sacct --starttime 2018-06-07 --format=job,start,account,maxrs -a -A rhstar | grep K 5030343.bat+ 2018-06-06T23:10:34 rhstar 381080K 5030371.bat+ 2018-06-06T23:01:57 rhstar 381984K 5030384.bat+ 2018-06-06T23:10:36 rhstar 384376K Thanks Jan_______________________________________________ pdsf-users mailing list
