myqueue 20.9.0

Simple job queue

MyQueue

MyQueue is a tool for submitting and keeping track of tasks running on a cluster of computers. It uses SLURM, PBS or LSF as a backend and makes handling of tasks easy. It has a command-line interface called mq with a number of sub-commands and a Python interface for managing workflows. Simple to set up: no system administrator or database required.

Features

• Easy task submission:

  • from the command line: mq submit <task> -R <cores>:<time>

  • from Python: myqueue.submit(...)

• Automatic restarting of timed-out/out-of-memory tasks with more time/cores

• Remembers your finished and failed tasks

• Powerful list command for monitoring

• Can be used together with Python venv‘s

• Folder-based Workflows

Examples

Submit Python script to 32 cores for 2 hours:

$ mq submit script.py -R 32:2h

Submit Python module abc.run in two folders:

$ mq submit abc.run F1/ F2/ -R 16:30m

Check results of tasks in current folder and its sub-folders:

$ mq list  # or mq ls
id  folder name      res.   age     state   time    error
--- ------ --------- ------ ------- ------- ------- ------
117 ./     script.py 32:2h  5:28:43 TIMEOUT 2:00:03
118 ./F1/  abc.run   16:30m 5:22:16 done      12:12
119 ./F2/  abc.run   16:30m 5:22:16 done      17:50
--- ------ --------- ------ ------- ------- ------- ------
done: 2, TIMEOUT: 1, total: 3

Resubmit with more resources (1 day):

$ mq resubmit -i 117 -R 32:1d
