Sometimes a submitted job writes no output to the log file for an extended period of time, looking like it is hanging. A common reason for this is the aggressive [[#Output_buffering|buffering]] performed by the Slurm scheduler, which will aggregate many output lines before flushing them to the log file. Often the output file will only be written after the job completes. If you wish to monitor the progress of your submitted job as it runs, consider running an [[#Interactive_jobs|interactive job]] | Sometimes a submitted job writes no output to the log file for an extended period of time, looking like it is hanging.

Often the output file will only be written after the job completes; and if the job runs out of time, part of the output may be lost.
