Use qdel to delete all my jobs at once, not one at

问题:

This is a rather simple question but I haven't been able to find an answer.

I have a large number of jobs running in a cluster (>20) and I'd like to delete them all and start over.

According to this site I should be able to just do:

qdel -u netid

to get rid of them all, but in my case that returns:

qdel: invalid option -- 'u'
usage: qdel [{ -a | -c | -p | -t | -W delay | -m message}] [<JOBID>[<JOBID>]|'all'|'ALL']...
   -a -c, -m, -p, -t, and -W are mutually exclusive

which obviously indicates that the command does not work.

Just to check, I did:

qstat -u <username>

and I do get a list of all my jobs, but:

qdel -u <username>

also fails.

Found the answer buried in an old supercluster.org thread:

qselect -u <username> | xargs qdel

Worked flawlessly.

Cannot comment, but building on what Gabriel answered:

qselect -u <username> | xargs qdel

qselect -u <username> -s <state> | xargs qdel

<state> would be R for running jobs only.

qselect will allow you to select job based on other criterias, like ressources asked (-l), destination queue (-q) ...

qdel -u <username>

will only work with SGE

回答3:

sometimes a simple grep/cut can help too: qstat | grep $USER | cut -d. -f1 | xargs qdel

This way we can also grep on a particular keyword for the jobs and delete them.

回答4:

Another possibility is to do qdel all. It deletes all jobs from everyone. When you don't have access for other people's job, it deletes only your jobs.

It is not the most beautiful solution, but it is surely the shortest!

# Delete all jobs owned by the current user.
# 
# Command breakdown:
# ------------------
#
# qselect
# -u selects all jobs that belong to the current user
# -s EHQRTW selects all job states except for Complete
#
# xargs
# --no-run-if-empty Do not run qdel if the result set is empty
#                   to avoid triggering a usage error.
#
# qdel
# -a delete jobs asynchronously
#
# The backslashes are a trick to avoid matching any shell aliases.

\qselect -u $(whoami) -s EHQRTW | \xargs --no-run-if-empty \qdel -a

Try

$ qdel {id1..id2}

So for example:

$ qdel {1148613..1148650}

回答7:

For UGE:

qstat -u | gawk '{print $1}' | xargs qdel

回答8:

qstat | cut -d. -f1 | sed "s;   \(.*\) 0;qdel \1;" | bash

sed's power.

回答9:

Just use the following command:

qdel all           

It will cancel all jobs running on cluster.
