The OpenHPC community is pleased to announce the release of OpenHPC v4.1, the latest update to the 4.x branch. This release delivers major version upgrades to core HPC libraries, modernizes the project’s documentation
infrastructure, and re-introduces the Paraver performance analysis tool.
Key Highlights in OpenHPC v4.1
Major Library Upgrades: This release brings significant version transitions across the HPC stack, including HDF5 2.x, MPICH 5.x, MVAPICH2 4.x, and Lmod 9.2.x. The Python ecosystem has also been updated with Cython 3.x,
mpi4py 4.x, and NumPy 2.x. Additional upgrades include Trilinos 17.0.0 and PETSc 3.25.0.
Documentation Modernization: The project has switched from LaTeX to a Markdown-based documentation system, making it easier for community members to contribute and maintain install guides.
Paraver Re-added: The Paraver performance analysis tool (v4.12.0), previously available in the 3.x branch, has been restored.
Streamlined Dependencies: Standalone packages for libfabric, autoconf, automake, and libtool have been removed in favor of system-provided versions. GEOPM packages have also been removed.
Extensive Validation: This release was validated with over 94,800 tests across 167 hours of testing.
