Optimizing experiments' software stack management with Spack

Spack is a package manager for supercomputers with a high degree of flexibility and specificity for managing software installations and with a focus for scientific applications. Spack is currently being used at CERN for building the Future Circular Collider (FCC) software stack. This project presents the improvements made to Spack for speeding up the build time and the upgrades which proceeded for bringing the compiler version used up to date.Spack is a package manager for supercomputers with a high degree of flexibility and specificity for managing software installations and with a focus for scientific applications.
