I would also suggest creating a calendar and put there all plans for massive
or timely computing in advance with approximate time required to accomplish
the job.

Dear Xavier,
This is a very good idea! As we keep growing our computing demands, we need
to use things like this. "Fairshare" is what one had at NERSC and we had at
the clusters at Berkeley and works extremely well.
I also agree about the maximum time command. People please start using it.
Xavier: Can I ask you to create a usage policy document draft that we can
start preparing amongst the members of the group via the wiki?

Hi all,
Since it is currently impossible to run jobs in eldorado queue of
odyssey without waiting for days, I asked the administrators to set a
"fairshare" scheduling policy. This means that priority for job
execution will be based on the time that users have consumed, so users
that use the cluster less will have higher priorities and their jobs
will run first.
In any case, to make a better use of the resources it is essential
that we start including the maximum run time for our jobs in the
script. This allows the scheduler to run small jobs in empty
processors that are waiting for large parallel jobs. The time is given
by the -W parameter of bsub, so for example, if you put
#BSUB -W 2:00
in the script, you are telling the system that the job will take at
most 2 hours (after that it will be killed).
Thanks,
Xavier
