Wessel is a very small server available to all users at the Department of Geosciences. A total of 24 processors is available but it is meant to be used for interactive access so only "small" (both memory and CPU usage, including small number of processors) simulations should be run on wessel.

Availability:

ESys-Particle is available on wessel (main server at the Department of Geosciences) and on the UIO HPC system called abel.

To check which version is available:


module avail esysparticle
------------------------------------- /cluster/etc/modulefiles ------------------------------------------------
esysparticle/2.1            esysparticle/2.2.2          esysparticle/2.2.2_patch    esysparticle/2.3.3(default)


To set-up your environment:


module load esysparticle

Running small test cases on wessel:

Wessel is a very small server available to all users at the Department of Geosciences. A total of 24 processors is available but it is meant to be used for interactive access so only "small" (both memory and CPU usage, including small number of processors) simulations should be run on wessel.

As a general rule, never use more than 8 processors and more than 8GB of memory. If you need more resources, please use abel (contact drift@geo.uio.no if you need further advice on how to access abel).

Analysing ESys-Particle outputs:

Running large simulation on abel:

When running large cases and more generally for your research, it is best to use HPC resources. On most HPC systems, you cannot run "interactively" for more than a limit of 30 minutes CPU. It is also likely you run ESys-Particule with MPI, using several processors.


Create a job command file

Create a script (or a job command file) where all the resources you need to run ESys-Particle are specified. Let call it esysparticle.job

#!/bin/bash
# Job name:
#SBATCH --job-name=run_esysparticle
#
# Project (change it to your NOTUR or uio project):
#SBATCH --account=XXXXX
#
# Wall clock limit (to be adjusted!):
#SBATCH --time=24:0:0
#
# Max memory usage per core (MB):
#SBATCH --mem-per-cpu=4G
#
# Adjust the number of processors (MPI tasks)
# SBATCH --ntasks=64
#
#Set up job environment: DO NOT CHANGE
export LANG=en_US.UTF-8 
export LC_ALL=en_US 
source /cluster/bin/jobsetup
ulimit -l unlimited
module load esysparticle


Please note that you need to adjust account (use your notur account if you have one or uio), time and ntasks (the number of processors required for your Esys-Particle simulation).

Adjust ntasks

The number of tasks your needs depend on your ESys-Particle configuration.

Submit/monitor your job command file

Submit your job

sbatch esysparticle.job

Monitor your job

squeue -u $USER
