If you wish to use the SCITAS clusters for an undergraduate or masters course then please read the following guide on the steps to follow.

 

How to request access

 

All requests should be submitted via this form and you will then be contacted by a member of the SCITAS team.

 

The following image shows an example of the form for classes.

 

 

 

What we need to know

 

The most important things for us are:

 

The name of an LDAP group that contains the list of participants

You need to create a group using groups.epfl.ch that contains all the participants including teaching assistants. 

The group must be public! The Manage attributes option on the group page allows you to do this.

 

 

What type of resources you need

Do you need a specific architecture or accelerators such as GPUs? Will you be running multi-node jobs using MPI?

If you have a preference for a particular cluster then let us know although we may not always be able to respect this choice.

  

When you need the resources

When is the course given and do students need access to the resources outwith these periods? 

 

 

What we do

 

We will give all members of the LDAP group access to the clusters and they will be to use the batch system to submit jobs.

 

If the course has practical sessions we will create a reservation for these periods to ensure that you have access to sufficient resources.

 

If access is required for a longer period the group will be given an allocation on the clusters and this will be dimensioned to as to give the participants access to sufficient resources.

 

We will provide you with the name of the course account for the batch system along with the reservation name if appropriate.

 

If you have a reservation then it will normally begin one hour before the time requested. Please use this period to test that things work as expected!

 

What to tell the participants

 

Depending on which cluster is to be used the participants will need to connect to one of the login nodes as explained at:

 

http://scitas.epfl.ch/getting-started/how-connect

 

Every participant has scratch space at /scratch/<name of course account>/<username> and this should be used for storing temporary files and writing output.

 

In addition to the standard options described in our guide to using the clusters the participants should add the following directives to their job scripts

 

#SBATCH  --account=<course account name>

#SBATCH   --reservation=<reservation name>

 

Please remind the students that after the course finishes their access will be revoked so they should copy any files that they wish to keep elsewhere.

 

Participants who undertake a project

 

If there are participants who carry out a project using the clusters after the end of the course they should apply for an individual account and explain that it is for a project.
