Excluding a Host

As with all cluster problems you encounter, if you know of a problematic host in the cluster, please send an email to hpcadmin@auburn.edu.  It may take some time for the cluster admins to respond, so in the meantime, you can avoid that host with the following syntax…

bsub -R “select[hname!=node000]” …

qsub -l h=!node001

Additionally, you can specify one or more hosts to use exclusively (still subject to slot availability)…

bsub -m “node001 node002 node003” …

qsub -l nodes=n001+node002
