Some slurm hacks

Firstly, I've aliased the following in my local .profile:

alias greatlakes="ssh -Y ${USERNAME}@greatlakes.arc-ts.umich.edu".

sping:

In order to see just the information I want to see about my current jobs, I use the alias

alias sping='squeue -u ${USERNAME} --format="%.18i %.60j %.2t %.10M"'

ijob

In order to create an interactive job with a certain number of processors and a certain amount of time, I do

function ijob {
NCPU=${2:-8}
MEM=${3:-2000}
TIME=${4:-1}
srun --job-name "$1" --cpus-per-task $NCPU --mem-per-cpu $MEM --time ${TIME}:00:00 --pty bash
}

The default is to create a job with 8 processors (i.e. virtual processors). The memory is 2 GB per cpu, and the time is 1 hour.
