[Mauiusers] Re: How to configure some limits

[Rob Lines]

I apologize for anyone that sees this twice. I somehow missed that there is
a separate list for maui from the torque list.

Hi everyone.  We are new to Torque/Maui and we are still getting a feel for
it.  We would like to put into place some limits so that the cluster is more
fairly shared.

For us on our old clusters we had a limit that no one person could have more
than 90% of the job slots used.  This allowed us to have people submit
thousands of jobs in a batch and let them go but still left a number of
slots for other people to run jobs.

With going to Torque/Maui we are looking to do something similar though as
we have more nodes it would be nice to be able to adjust that a bit so that
if there was only one person running jobs at that moment it would allow them
to use all the slots but the moment anyone else were to submit a job it
would become the next one to be run even if the first person had many more
jobs waiting and that had been waiting longer.

I have tried to read through the options and I am just not sure what I am
looking for so if someone can point me to the options that would work best
that would be great.

We are also are looking at some quirks because some of the software on the
cluster is not run via the queuing system so we sometimes have machines that
will reach a load where maui will not schedual things to those nodes so we
would not want to have 10% of the nodes in that state and then the other 90%
still being monopolized by that first big user thus locking out the later
queue user until either the big user were done or the other software user
were done.

Thanks for any insights,
Rob
