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.
Getting access
Fill out this form:
https://www.notur.no/notur/sites/drupal.uninett.no.notur/files/User-account-application-0613.pdf
NOTES
11. I would like an account on the following resources: abel
12. Start date (yyyy-mm-dd): use today's date End date (yyyy-mm-dd): when your project/contract ends (don't worry, we can extend access beyond that if needed)
13. Existing project (format nn****k for Notur):* NN9244K
14. Notur/NorStore user account (if you already have one): N/A
Otherwise provide preferred / local user name: _____________________ (max. 8 chars) -->Please fill out your UiO user name
15. If you want to use a grid certificate (GSI), provide the distinguished name (DN): N/A
Name of the project manager:* Kjetill Jakobsen
Give the form to Kjetill Jakobsen for submission. Ask Lex for help if needed.
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.
