Installed software

Important details!

When logging in to Saga and Betzy the MODULEPATH is set up to show all the default software module packages available. To get an overview of software installed issue command

module overview

Saga

For Saga the default software packages shown are for the Intel CPU partition with the NVIDIA P100 GPUs. If you want to use the AMD CPU partition with the NVIDIA A100 GPUs first issue command

module --force swap StdEnv Zen2Env

Olivia

Olivia is a quite different machine compared to the other NRIS HPC clusters. It is a HPE Cray computer, which provides the Cray Programming Environment (CPE) as means for advanced users to get the optimal performance when self-compiling code. In addition we have added NRIS software stacks compiled and optimized for Olivia’s nodes to ensure the best performance.

After logging in, no software stack is loaded by default. There are three types of stacks installed on Olivia:

  • Cray programming environment (CrayEnv) providing compilers, libraries and tooling optimized for HPE Cray systems

  • NRIS software stacks providing software and libraries installed by us

  • EESSI software stacks providing software and libraries curated by the European EESSI project and additional software installed locally on top of EESSI

See the available stacks with command

module available

You should see output similar to this:

------------------------------------------- /cluster/software/modules/Core -------------------------------------------
   CrayEnv    EESSI/2023.06 (S)    EESSI/2025.06 (S)    NRIS/CPU    NRIS/GPU    NRIS/Login    init-NRIS (S,L)

  Where:
   S:  Module is Sticky, requires --force to unload or purge
   L:  Module is loaded

Since Olivia has different node architectures there are three types of NRIS software stacks installed on Olivia:

  • NRIS/CPU: Contains software packages and libraries optimized for the CPU compute nodes.

  • NRIS/GPU: Currently includes libraries, compilers, and tools for building software for the Grace-Hopper 200 GPUs. In the future, this stack will also include AI frameworks such as PyTorch and TensorFlow.

  • NRIS/Login: Includes tools for pre- and post-processing data. Note: Do not use this stack for running workflows on the compute nodes.

As for EESSI there are two available software stacks:

  • EESSI/2023.06: Contains software packages and libraries optimized for toolchains foss/2022b, foss/2023a, and foss/2023b.

  • EESSI/2025.06: Contains software packages and libraries optimized for toolchains foss/2024a, foss/2025a, and foss/2025b.

Note

When building your software for production jobs make sure that you compile your code on a compute node. Allocate a compute node, e.g. running an interactive job (see Interactive jobs and load one of the NRIS/CPU or NRIS/GPU stacks.

Which extensions are available?

Modules can contain extensions (Perl modules, Python packages and R packages). Extensions are marked with an (E) and can not be loaded directly. You will have to find and load the module that contains the extension.

For example, list all versions of the Python package numpy that are installed:

module spider numpy

Five different version of numpy is installed in this example:

     Versions:
        numpy/1.22.3 (E)
        numpy/1.24.2 (E)
        numpy/1.25.1 (E)
        numpy/1.26.2 (E)
        numpy/1.26.4 (E)

Now list the module that contains a specific version of numpy:

module spider numpy/1.26.4

In this case it was the SciPy-bundle/2024.05-gfbf-2024a module that provides the Python package numpy version 1.26.4. In order to see what other extensions are included in the module, you can run:

module spider SciPy-bundle/2024.05-gfbf-2024a

We see that these Python packages are included in the module:


      Included extensions
      ===================
      beniget-0.4.1, Bottleneck-1.3.8, deap-1.4.1, gast-0.5.4, mpmath-1.3.0,
      numexpr-2.10.0, numpy-1.26.4, pandas-2.2.2, ply-3.11, pythran-0.16.1,
      scipy-1.13.1, tzdata-2024.1, versioneer-0.29

Note

If you do not want to see extensions in the output you can run the module command with the --nx option, like this: module --nx available

This catalogue lists software installed on NRIS HPC systems including the software available through the common EESSI software stacks, which can run on HPC systems as well as laptops, personal workstations, and cloud infrastructure:
