Introduction
We have been given a large allocation on Abel for computational work. This allocation runs out on April 30th, 2013. We can apply for renewal after that.

Using Abel
Interactive login
See also here.
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 here.
