Queue run

Manager task execution queues in parallel with a quenue depending on CPU/RAM load.

Description

The backlog is stored in a single file, or a directory of files if you specify a backlog directory. ⚠ Backlog entries are read from these files, the backlog file is deleted after all the tasks are executed.

Example

• Execute all tasks listed in protein-calculation.bl with up to three processes in parallel (-j). The backlog can be updated on the fly if you add the tasks at the end.

qrun -b protein-calculation.bl -j 3

• qrun accepts a directory with a multiple of backlogs.

qrun -b /tmp/backlog

• qrun can work in demon mode (-d). When tasks are added to the backlog, the tasks will be detected and executed.

qrun -b /tmp/backlog -j 5 -d

• Other example of demon mode

bash -c "/usr/bin/qrun -b /var/spool/qrun -j 2 -d >/var/log/qrun.log 2>&1 &"
