The cluster has 6 nodes (cronus, rhea, themis, tethys, oceanus and hyperion). For those nodes, 2 different queues are set:

• ttn.q is the main queue. It supports up to 64 slots per node.
• ttnS.h is a small queue, supporting 4 slots per node.

When using qsub or qlogin, and we do not specify the hostname we want to use (with the -l hostname=HNAME parameter), the cluster will assign our job to any queue with a free slot.

You can check the status of your jobs by simply typing

qstat

This will show only your jobs, as folks are not allowed to see each others jobs. However, there's a way to see, at least, how many slots each node has availables by typing:

qstat -q ttn.q -f
