Sacct -o JobID,JobName,AveCPU,AvePages,AveRSS,MaxRSSNode,AveVMSize,NTasks,State,ExitCode -j Note that your executable should be preceded by "srun" command for both serial and MPI executable. MaxRSS and MaxVMSize shows maximum RAM and virtual memory usage information for a job, respectively, while ReqMem reports the amount of RAM requested. For instance, the elapsed and Timelimit arguments allow for a comparison of allocated vs. We would suggest create an alias for running a customized version of sacct. The –format option is particularly useful, as it allows a user to customize output of job usage statistics. Note the jobs status for the users in a group eecs600 The job 676101 is estimated to start on April 09 at 15:25 and the end time of job 606057 is April 31 at 14:17.įiltering squeue output through awk may be useful, for example, to isolate entries with group name in common: Want to see details such as why your job is in PD (pending) state, in which node your job is running.ħ30814 batch slurm.sl bga11 PD 0:00 1 4 6950 (AssocMaxWallDurationPerJobLimiħ30815 batch slurm.sl bga11 PD 0:00 1 4 6950 (AssocMaxWallDurationPerJobLimiĩ89833 batch 3DClasse txh310 R 21:59:56 comp145t,comp146t,comp147t,comp149t,comp151t,comp154t,comp156t,comp157t,comp158t,comp159t,comp179t,comp185t,comp186t,comp187t,comp191t,comp192tĩ92383 batch job_chec sxl1036 R 1:43:13 2 16 3007 comp122t,comp123tĪlso, show the start time and end time of the job: Note the jobID (661587), status of the Job (R-> Running) and the compute node (comp150t) that the job is running.

It is good practice to include any setpkgs commands in your SLURM script. The example above simply prints the version of Python loaded in a user’s path. Lines beginning with the # symbol (without /bin/bash or SBATCH) are comment lines that are not executed by the shell. The commands needed to execute a program must be included beneath all #SBATCH commands. For instance, the #SBATCH –ntasks=1 line could be removed and a user could specify this option from the command line using: Optionally, any #SBATCH line may be replaced with an equivalent command-line option. Note that these are the defaults for any job, but it is good practice to include these lines in a SLURM script in case you need to request additional resources. This job (called just_a_test) requests 1 compute node, 1 task (by default, SLURM will assign 1 CPU core per task), 1 GB of RAM per CPU core, and 15 minutes of wall time (the time required for the job to complete). To submit this batch script, a user would type: # This example is loading Python 2.7.8 and then writing out the version of Python # Put commands for executing job below this line An example of a SLURM batch script (called simple.slurm) is shown below: The command sbatch accepts a number of options either from the command line, or (more typically) from a batch script. The sbatch command is used for submitting jobs to the cluster.
