EESSI: the research software streaming service

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. Stuttgart contributes to EESSI via the MultiXscale project and through the procurement of the molecular dynamics software ESPResSo as a pilot application. ESPResSo stable releases are available on the EESSI software stack and pre-releases are available on the EESSI development stack. Performance tests are available in the EESSI test suite and are periodically executed on HPC systems (dashboard). ESPResSo releases and pre-releases are used in continuous integration workflows in client applications pyMBE and SwarmRL via the EESSI GitHub Action.
