Setting up your environment

To set up the EESSI environment, simply run the command:

source /cvmfs/pilot.eessi-hpc.org/latest/init/bash

Warning

The EESSI pilot software stack is NOT READY FOR PRODUCTION!

Do not use it for production work, and be careful when testing it on production systems!

This may take a while as data is downloaded from a Stratum 1 server which is part of the CernVM-FS infrastructure to distribute files. You should see the following output:
