Direct login to simplex
Just like before the head node was available, direct login to simplex is available (with the caveat that particularly when the machine is busy, you are better off logging in to the head node.
If you ssh to
simplex.cs.unb.ca
, you will be given an interactive session with a small number of cores and a small memory and time allocation. Note that if the machine is busy you may have to wait a while for this session.If you need a large parallel interactive job, use
sinter
as your command to ssh. For example to run an interactive job with 20CPUS and 100G of memoryssh -t simplex.cs.unb.ca sinter -c 20 --mem 100G
This is just a simple wrapper for
srun
, the arguments are passed directly to srun.You can also use sinter if you want to run a small interactive job, but the machine is too busy to schedule your job the default amount of time
ssh -t simplex.cs.unb.ca sinter -c 2 --mem 4G --time 0:30:00
