For the software installation we are using the spack package manager.
The packages are available trough the enviromental modules Lmod.
Available modules cover mainly these areas:

• numerical linear algebra tools: openblas, matlab, lapack/scalapack
• scientific computation tools: suite-sparse, petsc, trilinos, hypre, fenics
• programming tools: R, comsol, matlab, julia, Mathematica
• parallel HPC tools: OpenMPI, globalarrays, PETSc
• vizualization tools: Paraview, Tecplot

Architecture selection

Since there are currently 3 different processor generations on the cluster nodes, the user has to select the deisred target architecture. (since the login node r3d3 is in the class Arch/linux-ubuntu20.04-skylake_avx512 this architecture is preloaded by default.)

• Use module add Arch/linux-ubuntu20.04-skylake_avx512 for queues express3, long3, astro, core36 - nodes r3X and r4X
• Use module add Arch/linux-ubuntu20.04-ivybridge for queues express/short/long for nodes r2X
• Use module add Arch/linux-ubuntu20.04-sandybridge for queue edu (nodes rX)
