For Merlin7 the *package manager for supercomputing* [Spack](https://spack.io/) is available. It is meant to compliment the existing PModules
solution, giving users the opertunity to manage their own software environments.

Documentation for how to use Spack on Merlin7 is provided [here](https://gitlab.psi.ch/lsm-hpce/spack-psi/-/blob/main/README.md).

## The Spack PSI packages

An initial collection of packages (and Spack reciepes) are located at <https://gitlab.psi.ch/lsm-hpce/spack-psi>, users can directly use these
through calls like `spack add ...`.
