EESSI

The European Environment for Scientific Software Installations (EESSI, pronounced as "easy") is a collaboration between different European partners in HPC community.
The goal of this project is to build a common stack of scientific software installations for HPC systems and beyond, including laptops, personal workstations and cloud infrastructure.

EESSI pilot software stack (2021.12)

Caveats

The current EESSI pilot software stack (version 2021.12) is the 7th iteration, and there are some known issues and limitations, please take these into account.

 First of all: 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!

Set up your EESSI environment

You can set up the environment by sourcing the provided init script:

 source /cvmfs/pilot.eessi-hpc.org/versions/2021.12/init/bash

If all goes well, you should see output like this:

 Found EESSI pilot repo @ /cvmfs/pilot.eessi-hpc.org/versions/2021.12!
 Using x86_64/intel/haswell as software subdirectory.
 Using /cvmfs/pilot.eessi-hpc.org/versions/2021.12/software/linux/x86_64/intel/haswell/modules/all as the directory to be added to MODULEPATH.
 Found Lmod configuration file at /cvmfs/pilot.eessi-hpc.org/versions/2021.12/software/linux/x86_64/intel/haswell/.lmod/lmodrc.lua
 Initializing Lmod...
 Prepending /cvmfs/pilot.eessi-hpc.org/versions/2021.12/software/linux/x86_64/intel/haswell/modules/all to $MODULEPATH...
 Environment set up to use EESSI pilot software stack, have fun!
 [EESSI pilot 2021.12] $ 

!NOTE: You might see the following error which can be ignored:
ERROR: ld.so: object 'libgtk3-nocsd.so.0' from LD_PRELOAD cannot be preloaded (cannot open shared object file): ignored.

Now you're all set up! Go ahead and explore the software stack using module avail, and go wild with testing the available software installations!

Testing the EESSI pilot software stack

Please test the EESSI pilot software stack as you see fit: running simple commands, performing small calculations or running small benchmarks, etc.
Test scripts that have been verified to work correctly using the pilot software stack are available at https://github.com/EESSI/software-layer/tree/main/tests.
