CERN ROOT software

Information on running CERN’s ROOT software on the Odyssey cluster.

CentOS 7 / Installing For Yourself

To run the current version of ROOT, you will need to install the package yourself in your home directory using CERN’s package in order to run it on the cluster.
You will need to source the ROOT setup script in your installation (thisroot.sh) before running ROOT. 
Please follow CERN’s instructions for the location of that.

CentOS 6 Legacy Module

For the cluster, you should install this for yourself on CentOS 7. However, at your own risk, you can try running the CentOS 6 module on Odyssey 3.
To use it requires loading the CentOS 6 compatibility module, a GCC module, and the ROOT module root/6.02.10-fasrc01
Description:
A modular scientific software framework. It provides all the functionalities needed to deal with big data processing, statistical analysis, visualisation
and storage.
This module can only be loaded through the following modules:

module load centos6/0.0.1-fasrc01

module load gcc/4.8.2-fasrc01 root/6.02.10-fasrc01
You then need to follow ROOT’s regular usage instructions and source its setup script:
source thisroot.sh
