Introduction
If you have many jobs that are very similar and, importantly, independent then you can use the High Performance Computing Service [[1]].
The website is helpful, but below are a few commands that I think supplement their FAQs. Please do edit (or email me and I'll update the wiki) if you have any further suggestions.
If you want to see all the jobs you've submitted
As you may guess, qstat gives you some statistics on the queues. To look for just your jobs type:
qstat -u <user_id> eg: qstat -u kw401
If you want to delete all the jobs you've submitted
To just get the job IDs you need to use qselect and pipe these to qdel (which deletes the job) using xargs.
qselect -u <user_id> | xargs qdel
eg: qselect -u kw401 | xargs qdel
Type man xargs if you want to know more about this terribly useful command which pipes information from standard input into the next command.
