Software Stages Changelog

Changelog for stage 2026

Version changes in packages of major importance

• GCC updated to 14.3.0

• intel-compilers updated to 2025.2.0

• NVHPC (now named nvidia-compilers) updated to 25.9

• ParaStationMPI updated to 5.13.0-1

• OpenMPI updated to 5.0.8

• Python updated to 3.13.5

• EasyBuild updated to 5.1.2

General software stack changes

• Changed how modules are hidden. Instead of using an EasyBuild hook, modules are now hidden by Lmod configuration files.

• The LLVM module is now a full installation of LLVM instead of only providing a minimal installation. Unlike Clang, LLVM will not automatically load the CUDA module.

  • Clang is now just a wrapper around the LLVM module. The Clang module is deprecated and will be removed in future stages.

• The NVHPC module was renamed to nvidia-compilers. This includes the following changes:

  • The NVHPC is deprecated. Loading it will display a warning, and loads nvidia-compilers.

  • nvidia-compilers will now always use the CUDA provided by the CUDA module.

  • Nsight-Compute and Nsight-Systems are no longer provided by nvidia-compilers. Please load these modules separately.

  • OpenMPI 5.0.8 and ParaStationMPI 5.13.0-1 are provided on top of nvidia-compilers, just like in prior toolchains.

• The Intel toolchain includes the following changes:

  • FlexiBLAS will not be provided, due to issues building the software on some nodes.

• The CUDA module differs between systems:

  • On JUWELS and JUSUF, CUDA/12 provides CUDA/12.9.1

  • On JURECA-DC, JUPITER and JUWELS Booster, CUDA/13 provides CUDA/13.0.0

• The FlexiBLAS module now includes AOCL-BLAS as a backend in addition to MKL, OpenBLAS and BLIS. On JUPITER, it provides NVPL instead of AOCL-BLAS.

• The OpenGL module will now not provide glew anymore. Please load glew separately, if required.

Notable new software

• The performance assessment tool HPCToolkit is now available. No CUDA version will be provided, as HPCToolkit does not support CUDA/13 yet.

• The editor helix is now available. Users might need to set COLORTERM=truecolor for full functionality.

Known issues

• Using numba.cuda of the numba module may not work with the latest CUDA. Please load the additional numba-cuda module, which provides the now recommended CUDA bindings for numba.

• The MPI-settings modules set this environment variable to work around an issue in psmgmt: PSPMIX_ENV_TMOUT=20

Changelog for stage 2025

General software stack changes

• As of 2025 romio321 is not working, so the chosen io component of OpenMPI is changed to romio341. Additionally, ufs is selected as the filesystem type for romio341.

  • Change in the MPI-settings modules:

  'OMPI_MCA_io': 'romio341',
  'ROMIO_FSTYPE_FORCE': 'ufs:'
  

Version changes in packages of major importance

• GCC updated to 13.3.0

• intel-compilers updated to 2024.2.0

• NVHPC updated to 24.9 (and 25.1)

• ParaStationMPI updated to 5.10.0-1

• OpenMPI updated to 5.0.5

Changelog for stage 2024

General software stack changes

• General move towards FlexiBLAS with MKL, BLIS and OpenBLAS as backends.

  • Applies to gcccoreflexiblas (as opposed to gcccoremkl), and the upper level toolchains, also with other compilers.

• mpi-settings modules are now deprecated in favour of MPI-settings.

Version changes in packages of major importance

• GCC updated to 12.3.0

• ParaStationMPI updated to 5.9.0-1

• OpenMPI updated to 4.1.5

Software distribution-related changes

• Python is now just a base installation with basic extensions. Most of the other Python extensions are part now of the Python-bundle-PyPI/2023.06 module.

• Perl is now just a base installation with basic extensions. Most of the other Perl extensions are part now of the Perl-bundle-CPAN/5.36.1 module.

WIP packages

Deprecated packages

• nvidia-driver module no longer available. The functionality is now split between RPMs installed in the OS and the OpenGL module.

• libelf is not used as a dependency, so it has been marked as deprecated. The library itself is part of the elfutils package.

• LCov was not used anymore

• SuperLU was not used anymore

• cppcheck was not used anymore

Renamed packages

Changelog for stage 2023

General software stack changes

• Custom installations are now supported via the UserInstallations module (see documentation)

• OpenMPI now supports UCC (which supports SHARP and NCCL as backends)

Version changes in packages of major importance

• GCC updated to 11.3.0

• ParaStationMPI updated to 5.6.0-1

• OpenMPI updated to 4.1.4

• IntelMPI updated to 2021.6.0

Software distribution-related changes

• imkl has been split in imkl, which contains the binary libraries for most of the MKL functionality, and imkl-FFTW, which contains the FFTW MPI-wrappers.

• IntelMPI now leverages the MPICH ABI compatibility with ParaStationMPI and reuses its stack (packages are no longer compiled for IntelMPI in a separate toolchain)

• gomkl toolchain (GCC + OpenMPI + MKL) was replaced by the toolchain foss (GCC + OpenMPI + FlexiBLAS). FlexiBLAS allows you to change between MKL, OpenBLAS and BLIS. You can list all installed backends and the complete configuration: flexiblas list. Changing the backend can be done for example by seeting FLEXIBLAS=OPENBLAS.
