[Nelsonlab-admin] cluster tips

[Allen D. <all...@uc...>]

Hi Jared,

When you submit jobs, please specify the queue you with them to go to.  Now
that we have multiple queues, the default behavior of the qsub utility is to
first put jobs to all.q, then to gb4.q, then to celsius.q, faulting down the
chain if a queue is currently full.  We're working on making all jobs go to
only all.q unless otherwise requested, but until then if you do not need the
bigmem queue, please explicity request all.q with the "-q all.q" option to
qsub.

Also, it appears that the I/O your jobs were doing over the last couple of
days were putting a heavy load on the xsan NFS processes.  It appeared that
you were touching a large number of small files.  Please copy your files
over to nucleus:/clustertmp/jaredfox that are going to be used from the
compute nodes.  This volume is NFS exported to all the compute nodes.

Thanks.

-Allen
