Programming Environments

CSCS provides “programming environments” on Alps vClusters that provide compilers, MPI, and commonly used libraries and packages, that can be used to build applications from source.

  • prgenv-gnu uenv

    Provides compilers, MPI, tools and libraries built around the GNU compiler toolchain. It is the go to programming environment on all systems and target node types, that is it is the first that you should try out when starting to compile an application or create a python virtual environment.

  • prgenv-nvfortran uenv

    Provides a set of tools and libraries for building applications that need the NVIDIA Fortran compiler, commonly required for OpenACC and CUDA-Fortran applications.

  • linalg uenv

    Provides compilers, MPI and Python, along with linear algebra and mesh partitioning libraries for a broad range of use cases.

  • julia uenv

    Provides a complete HPC setup for running Julia efficiently at scale, using the supercomputer hardware optimally.

  • Cray Programming Environment containers

    The Cray Programming Environment (CPE) is a suite of compilers, libraries and tools provided by HPE.

    These are the “Cray Modules”, familiar to users of old Piz Daint and other HPE/Cray clusters.
