Scientific computing runs on AlmaLinux
Grant cycles last years, reproducing a paper can take months, and clusters often run for the whole life of their hardware. AlmaLinux gives scientific computing a predictable, RHEL-compatible base with a long lifecycle, current toolchains, and no subscription gating.
- 10 years
- of support for every major release
- 4 architectures
- x86_64, aarch64, ppc64le, s390x
- No subscription
- every repository, free to everyone

Running at research institutions and HPC integrators
Built for the demands of research
What HPC teams need from a base OS: a long lifecycle, compatibility, fast fixes, and current tools.
A lifecycle that matches research timelines
AlmaLinux 9 is supported through 2032, and AlmaLinux 10 through 2035. A cluster you build today can run for its whole hardware life without a forced OS migration partway through a grant.
Compatible with RHEL and the HPC stack
Schedulers, parallel filesystems, vendor drivers, and ISV codes that list RHEL as supported run on AlmaLinux unchanged. OpenHPC's 3.x and 4.x releases target Enterprise Linux 9 and 10.
Fast, open security patching
We build and ship security fixes quickly, and the work happens in public, so you can see and engage with the volunteers working on the problem. Research teams at CERN, UCL, and CSIC all named this as a reason they run AlmaLinux.
Current compilers and GPUs
The system GCC stays steady so the ABI doesn't break, and current GCC ships alongside it in gcc-toolset packages, so you can compile with GCC 15 against a stable runtime. If you build your own toolchains, Spack publishes official AlmaLinux 8 and 9 images to build them on.
For GPUs, we build and ship NVIDIA driver packages for AlmaLinux 9 and 10, and one package sets up NVIDIA's CUDA repository alongside them.
Install NVIDIA drivers and CUDABenefits specifically for our community
AlmaLinux 10 adds a few things on top of RHEL compatibility: an x86_64_v2 build for older hardware that RHEL 10 drops, and Btrfs support, including booting from a Btrfs volume. It runs on x86_64, aarch64, ppc64le, and s390x.
For the community, by the community
AlmaLinux is free for anyone to download and run, on one workstation or a thousand compute nodes, with no subscription manager or license tracking. It's just as free and easy to get involved: the project is governed by its members, roadmap discussions happen in public, and HPC users are welcome to help shape them.
Hear from the people running it
Research teams on why they build on AlmaLinux.
It has 37,888 cores of Intel Xeon Platinum with MRDIMM memory for the memory bandwidth. It's got a 400 gigabit Slingshot network as the interconnect. That's all running AlmaLinux.
AlmaLinux helps us maintain a robust and scalable research environment so we can focus on advancing biomedical discovery through computational science and artificial intelligence.
We migrated our entire infrastructure to AlmaLinux when CentOS was discontinued. We chose Alma because it gives us 10 years of security patches and support.
Thank you to SIE LADÓN for recording and editing the Biogipuzkoa and CSIC videos.
The HPC & AI SIG
The AlmaLinux HPC & AI Special Interest Group is a community of cluster engineers, research software developers, and open source contributors working together to make AlmaLinux the best platform for scientific computing.
- MPI stacks and scientific libraries
- OpenHPC alignment and testing
- Cluster deployment guidance
- Direct collaboration with hardware and software vendors
AlmaLinux helps power the Worldwide LHC Computing Grid, involving 150+ partner institutes, providing 1M+ modern cores and 4+ Exabytes of storage. The AlmaLinux track record of rapid security patching has been particularly invaluable for the stability of our infrastructure!
How to get started
Three paths, depending on where you are today.
1
Download AlmaLinux
Get the latest images for your architecture. Bare-metal installers, cloud images for AWS, Azure, and GCP, and container base images are all available.

Migrating from CentOS, RHEL, Rocky, or Oracle?
To switch to AlmaLinux on the same major version, almalinux-deploy converts a running CentOS, RHEL, Rocky Linux, or Oracle Linux 8, 9, or 10 system in place, with no reinstall.
AlmaLinux 10.1 and later support Btrfs, so EL10 systems running Btrfs, including Oracle Linux, can switch without changing filesystems.
To move to a newer major version, ELevate handles in-place upgrades, including the AlmaLinux 9 to 10 x86_64_v2 path for older hardware.

Join the community
The HPC & AI SIG meets monthly, and its mailing list, chat, and meeting notes are on the SIG wiki page. If you run AlmaLinux in production at an HPC site, we'd especially like to hear from you.
