Using Abel

ssh abel.uio.no

Getting a single cpu for 11 hrs

qlogin --account nn9244k --nodes 1 --ntasks-per-node 1

Same, for 24 hrs

qlogin --account nn9244k --nodes 1 --ntasks-per-node 1 --time 24:00:00


NOTE you aresharing the node with others, do no use more than the number of cpus you asked for

NOTE a pipeline of unix commands may use one cpu per command:

grep something somefile | sort | uniq -c

This may use three cpus!


Getting a whole node with 16 CPUs and 64 GB RAM:

qlogin --account nn9244k --nodes 1 --ntasks-per-node 16 --time 24:00:00

Even though each node has 16 cpus, due to hyperthreading, you can run up to 32 processes simultaneously


You have a large work area available as well:

echo $SCRATCH
cd $SCRATCH

Using

squeue -u your username

will tell you the job ID, the work area is

/work/jobID.d

NOTE all data on this area is deleted once you log out


Quitting:

logout (or ctrl-d)

SLURM scripts
Information coming, until then see [http://www.uio.no/english/services/it/research/hpc/abel/help/user-guide/queue-system.html here].
