There are some Limitations that mention backfill on the heterogeneous job support page.
https://slurm.schedmd.com/heterogeneous_jobs.html#limitations Maybe there’s some information there to help? Ken From: slurm-users <slurm-users-boun...@lists.schedmd.com> On Behalf Of Ana Jokanovic Sent: Thursday, November 29, 2018 4:28 AM To: slurm-users@lists.schedmd.com Subject: [slurm-users] backfill scheduler does not work for heterogeneous jobs (version 17.11) Hello, I did a simple test submitting the workload of three jobs (see below) on a cluster of 5 nodes: sbatch --cpus-per-task=2 --ntasks=6 --time=15 : --cpus-per-task=2 --ntasks=6 --time=15 : --cpus-per-task=2 --ntasks=6 --time=15 sbatch --cpus-per-task=2 --ntasks=6 --time=15 : --cpus-per-task=2 --ntasks=6 --time=15 : --cpus-per-task=2 --ntasks=6 --time=15 sleep 5; sbatch --ntasks=1 --time=2 : --ntasks=1 --time=1 I would expect that the third submitted job is backfilled but it does not happen. Here is the job completion log: JobId=2 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:15:00 SubmitTime=1543317694 StartTime=1543317714 EndTime=1543317774 NodeList=s19r2b09 NodeCnt=1 ProcCnt=48 JobId=3 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:15:00 SubmitTime=1543317694 StartTime=1543317714 EndTime=1543317774 NodeList=s19r2b10 NodeCnt=1 ProcCnt=48 JobId=4 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:15:00 SubmitTime=1543317694 StartTime=1543317714 EndTime=1543317774 NodeList=s19r2b12 NodeCnt=1 ProcCnt=48 JobId=8 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:02:00 SubmitTime=1543317699 StartTime=1543317804 EndTime=1543317824 NodeList=s19r2b14 NodeCnt=1 ProcCnt=48 JobId=9 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:01:00 SubmitTime=1543317699 StartTime=1543317804 EndTime=1543317824 NodeList=s19r2b16 NodeCnt=1 ProcCnt=48 JobId=5 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:15:00 SubmitTime=1543317694 StartTime=1543317804 EndTime=1543317864 NodeList=s19r2b09 NodeCnt=1 ProcCnt=48 JobId=6 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:15:00 SubmitTime=1543317694 StartTime=1543317804 EndTime=1543317864 NodeList=s19r2b10 NodeCnt=1 ProcCnt=48 JobId=7 UserId=3113 GroupId=8950 Name=sleep JobState=COMPLETED Partition=debug TimeLimit=00:15:00 SubmitTime=1543317694 StartTime=1543317804 EndTime=1543317864 NodeList=s19r2b12 NodeCnt=1 ProcCnt=48 Would you expect this behavior?
