The tutorials will be run on the CECAM linux ''cluster''.

* If connecting from the CECAM iMac, your username is indicated on the terminal (''tutoXY'').

* If connecting from your notebook, choose a username [[CECAM accounts 2017|from this list (link)]]

=== Standard tutorials: cecampc4 cluster ===

Log into the cluster via:
$ ssh -Y tutoXY@cecampc4.epfl.ch
replacing ''XY'' with the appropriate number.

Next you '''must''' log into the linux cluster directly, using the node ''node0RS'' that is [[CECAM accounts 2017|associated with the username (link)]], and set up the tutorial as follows:
$ ssh -Y node0RS
$ pwd
/nfs_home/tutoXY
$ which pw.x yambo
/nfs_home/tutoadmin/bin/pw.x
/nfs_home/tutoadmin/bin/yambo
$ cd /home/scratch/ ''(NB: do '''not''' run on the /nfs_home partition!)''
$ mkdir yambo_YOUR_NAME ''(there are more participants than accounts!)''
$ cd yambo_YOUR_NAME
$ cp /nfs_home/tutoadmin/yambo-2017/tutorials/hBN.tar.gz .
$ cp /nfs_home/tutoadmin/yambo-2017/tutorials/hBN-2D.tar.gz .
$ tar -zxvf hBN.tar.gz
$ tar -zxvf hBN-2D.tar.gz
$ ls
YAMBO_TUTORIALS

If you used "ssh -Y", X-forwarding, for plotting with gnuplot, ''should'' work. If not, try <code>set DISPLAY:0.0</code> on your local machine; it might also help to keep one terminal open for plotting and the other for running codes. If all else fails, try the cool gnuplot trick <code>gnuplot> set terminal dumb</code>.

=== Parallel tutorial: bellatrix cluster ===

This cluster is equipped with 16-core nodes based on Intel processors.
A tutorial-dedicated queue (''cecam_course'') allows participants to access up to 20 nodes.

First log into the cecam4 cluster via:
$ ssh -Y tutoXY@cecampc4.epfl.ch
replacing ''XY'' with the appropriate number.


Next move into the bellatrix cluster via:
$ ssh -Y cecam.schoolXY@bellatrix.epfl.ch
$ cd /scratch/${USER} (NB: do not run in the /home folder!)
$ mkdir yambo_YOUR_NAME (there are more participants than accounts!)
$ cd yambo_YOUR_NAME
replacing ''XY'' with the appropriate number.

This cluster is equipped with 16-core nodes based on Intel processors.

The Unix intel environment can be obtained by loading the following modules:
module purge
module load intel/16.0.3
module load intelmpi/5.1.3
module load python

A tutorial-dedicated queue (''cecam_course'') allows participants to access up to 20 nodes.
In order to submit to this queue you will use a submission script ''run.sh'' you will find in the tarball provided for the tutorials.
