Logging on the compute nodes

Some times you may want to log on a compute node (for instance to check out output files on the local work area on the node), and this is also done by using SSH. From stallo.uit.no you can log in to compute-x-y the following way:

ssh -Y compute-x-y		(for instance: ssh compute-5-8)

or short

ssh -Y cx-y		(for instance: ssh c5-8)

If you don't need display forwarding you can omit the "-Y" option above.

If you for instance wants to run a program interactively on a compute node, and with display forwarding to your desktop you should in stead do something like this:

1. first login to Stallo with display forwarding,
   
2. then you should reserve a node, with display forwarding, trough the queuing system

ssh -Y stallo.uit.no                       1) Long in on Stallo with display forwarding.
qsub -lnodes=1,walltime=1:0:0 -I -X        2) Reserve and log in on a compute node with display forwarding.
