Univ computing

Basic Tech

1. There are two ways to connect to lts. (just see the guidance on Research Computing Resources)
   • ssh x.500@apollo.cla.umn.edu or ssh x.500@athena.cla.umn.edu
   • use Nomachine client to log in

If using ssh, then there would be no graphic display. In such a case, after using ssh compute to get into the compute session, qsub -IX would not work. Instead, we need to use qsub -I, which supports non-graphic option.

Or, I could just use ssh x.500@compute.cla.umn.edu to log in compute. Do remember qsub -I before loading modules and starting to compute.

1. @c2 means that I am the 2nd in the queue.

2. In order to use wts, the software to download is Microsoft Remote Desktop 8, not Microsoft Remote Desktop 10, since the guidance on the univ wts is based on version 8. Besides, the vpn should be connected beforehand.
