Software layer

Software layer

The top layer of the EESSI project is the software layer, which provides the actual scientific software installations.

To install the software we include in our stack, we use EasyBuild, a framework for installing scientific software on HPC systems. These installations are optimized for a particular system architecture (specific CPU and GPU generation).

To access these software installation we provide environment module files and use Lmod, a modern environment modules tool which has been widely adopted in the HPC community in recent years.

We leverage the archspec Python library to automatically select the best suited part of the software stack for a particular host, based on its system architecture.

The software layer is maintained through our GitHub repository.
