Project ID: 38091


HEPrpms is a repository that contains the Monte Carlo Event Generators used in High Energy Physics and related tools. The repository supports RHEL8-compatible distributions and some of the latest Fedora releases. The spec files and patches can be found at https://github.com/andriish/HEPrpms The packages are compiled with the maximal set of features. Some exceptions are listed below.

Exceptions in dependencies and features for El8:

  • The support of Delphes for SHERPA-MC is disabled, and the interface is defunct
  • The OpenLoops package is compiled with a limited set of processes
  • The recola2 package is compiled only with the SM (Standard Model) model files

For most packages, the sources are taken from their upstream repositories and only some patches that allow for the builds are applied. However, some packages contain an extended functionality of a larger amount of added codes or are even created from scratch. These packages are:

  • fjcontrib -- added compilation of shared libraries
  • lhapdf-sets-Herwig and lhapdf-sets-whizard -- technical packages created from scratch that provide a set of PDFs needed to build Herwig and whizard

For various reasons, the source codes for some packages are provided internally, i.e. not downloaded at build time from the upstream. These packages are:

  • cernlib -- the latest published version
