Hands-on sessions

Some useful information about the Hands-on sessions can be found on this site:

Accessing DiARC HPC
We would like to invite you to sign up for an account on the DIaL HPC (DiRAC) cluster which will be available to you for the duration of the course and for a short while afterwards, to allow you to complete the practical exercises and put some of what you have learned into practice.
To sign up
You must first register for an account on SAFE, https://dirac-safe.readthedocs.io/en/latest/safe-guide-users.html and then request your machine account under project dp114. https://dirac-safe.readthedocs.io/en/latest/safe-guide-users.html#dirac-systems-accounts-passwords
When signing up, please make sure you use a university e-mail address (i.e. not gmail, Hotmail, yahoo etc).
You will need to provide IP addresses of the machines you will be using to connect to DiRAC. These should be your institutional machines, just one or two should be enough (separated by commas) or a range in the form xx.xx.xx.00/yy. During the hands-on sessions In Prague you will have to ssh to DiRAC via one of these machines.
Accessing DiRAC
To connect to the DiAL machine use: ssh -X @dirac03.rcs.le.ac.uk The project folders are /scratch/dp114/.
There are plenty of modules, most likely you will find compilers and libraries you will need.
Running calculations on DiRAC
For lightweight things you can just run python interactively on a login node. If you are going to do something that would be disruptive to other users you should launch an interactive job qsub -I -q highmem -l walltime=4:00:00 -A dp114
To use python's Jupiyer notebook
ssh -X -L 8888:localhost:8888 @dirac03.rcs.le.ac.uk
where 8888 is some port number
module load python/intel/3.6.3
jupyter notebook --no-browser
Copy/paste an URL generated into your browser when you connect for the first time, in the form

We acknowledge the support from the STFC DiRAC HPC Facility for providing the computational resources for the hands-on sessions.
