VersatusHPC Fork

This is the VersatusHPC fork of OpenHPC, extending the upstream project with additional platform support:

Platform	Architecture	Status
EL10 (AlmaLinux/Rocky/RHEL)	ppc64le (IBM POWER)	Available
openEuler 24.03 LTS	ppc64le (IBM POWER)	Available
Ubuntu 24.04 LTS	x86_64	Release candidate
Ubuntu 24.04 LTS	ppc64el (IBM POWER)	Release candidate

Ubuntu 24.04 Port

The ubuntu-port work adds Debian packaging for the OpenHPC 4.x package matrix on Ubuntu 24.04 LTS. The x86_64 build is performed in OBS project VersatusHPC:OHPC:4, repository Ubuntu_24.04; the ppc64el build is performed natively on IBM POWER and merged into the same public APT repository.

As of 2026-04-19, the Ubuntu x86_64 OBS build is published with 296/296 packages succeeded. The public repository also includes the architecture portable ppc64el package set. Runtime validation covers a Warewulf/Slurm Ubuntu 24.04 head node and compute node, including GNU15 and Intel compiler coverage on x86_64 across OpenMPI, MPICH, MVAPICH2, and Intel MPI, plus GNU15 OpenMPI, MPICH, MVAPICH2, LIKWID, and linkage checks on ppc64el.

Pre-built Debian packages are available at: https://repos.versatushpc.com.br/openhpc/versatushpc-4/updates/Ubuntu_24.04/

To enable the Ubuntu repository:

sudo install -d -m 0755 /usr/share/keyrings /etc/apt/sources.list.d
OHPC_REPO_ROOT=https://repos.versatushpc.com.br/openhpc/versatushpc-4
curl -fsSL "${OHPC_REPO_ROOT}/versatushpc.gpg" \
  | sudo tee /usr/share/keyrings/versatushpc.gpg >/dev/null
curl -fsSL "${OHPC_REPO_ROOT}/updates/Ubuntu_24.04/versatushpc-openhpc.list" \
  | sudo tee /etc/apt/sources.list.d/versatushpc-openhpc.list >/dev/null
sudo apt update
sudo apt install ohpc-release

For a full SMS/compute-node installation, follow the Ubuntu Warewulf/Slurm installation guide, generated from the upstream LaTeX manual structure.

Operational validation is documented in docs/ubuntu-port/VALIDATION.md and automated by scripts/validate-ubuntu-runtime.sh. The native POWER Debian build path is documented in docs/ubuntu-port/PPC64EL.md; cross-distribution POWER release checks are documented in docs/POWER-VALIDATION.md.

The port keeps the OpenHPC compiler/MPI package model, using Debian packaging under components/**/debian*, shared build helpers under devel/, and local OBS import/runtime tooling under obs/. Intel oneAPI dependencies are resolved through OBS Debian Download-on-Demand against Intel's upstream APT repository.

ppc64le Port

The versatushpc/4.x branch provides full OpenHPC 4.x support for ppc64le (IBM POWER9+) on EL10 and openEuler 24.03. All 68 architecture-portable components from the official OpenHPC component list are built and available, including compilers (GCC 15), MPI stacks (OpenMPI 5, MPICH, MVAPICH2), SLURM, OpenPBS, and the complete scientific library stack (PETSc, Trilinos, Boost, HDF5, NetCDF, etc.).

Only components that are inherently architecture-locked are excluded: Intel compilers/MPI, CUDA, ARM compilers, geopm, and msr-safe.

The spec file changes are minimal (~90 lines across 21 files) and fully conditional (%ifarch ppc64le), preserving compatibility with upstream x86_64 and aarch64 builds.

Pre-built RPMs are available at: https://repos.versatushpc.com.br/openhpc/versatushpc-4/updates/

All packages are signed with the VersatusHPC GPG key. To enable the repo:

# EL10
curl -o /etc/yum.repos.d/versatushpc-openhpc.repo \
  https://repos.versatushpc.com.br/openhpc/versatushpc-4/updates/EL_10/versatushpc-openhpc.repo

# openEuler 24.03
curl -o /etc/yum.repos.d/versatushpc-openhpc.repo \
  https://repos.versatushpc.com.br/openhpc/versatushpc-4/updates/openEuler_24.03/versatushpc-openhpc.repo

Community building blocks for HPC systems

Introduction

This stack provides a variety of common, pre-built ingredients required to deploy and manage an HPC Linux cluster including provisioning tools, resource management, I/O clients, runtimes, development tools, containers, and a variety of scientific libraries.

There are currently three release series: the 2.x, the 3.x and the 4.x which target different major Linux OS distributions:

• The 2.x series targets EL8 and Leap15.
• The 3.x series targets EL9, Leap 15 and openEuler 22.03.
• The 4.x series targets EL10, openEuler 24.03, and Ubuntu 24.04 in this fork.

Getting started

OpenHPC provides pre-built binaries via repositories for use with standard Linux package manager tools (e.g. dnf or zypper). To get started, you can enable an OpenHPC repository locally through installation of an ohpc-release RPM which includes gpg keys for package signing and defines the URL locations for [base] and [update] package repositories. Installation guides tailored for each supported provisioning system and resource manager with detailed example instructions for installing a cluster are also available. Copies of the ohpc-release package and installation guides along with more information is available on the relevant release series pages (2.x, 3.x or 4.x).
