SIGs/HC

Heterogeneous Computing Special Interest Group

Mission

To encourage the packaging and accessibility of heterogeneous computing projects in Fedora and EPEL. This includes machine learning, OpenCL, and scientific computing.

Communication

While separate from the AI/ML SIG, we do share communication channels for now. If you're interested, please join us on:

• #ai-ml@fedoraproject.org Matrix room
• #fedora-ai-ml on libera.chat IRC (NOTE: With the recent Matrix/IRC bridge issues, there may not be much activity on IRC. More conversation happens in the Matrix room)
• #ai-ml-sig on Fedora's Discourse instance

Members/Packagers/Reviewers

• Jeremy Newton (ROCm related)
• Felix Schwarz (currently busy with certbot, borgbackup, WeasyPrint)
• Benson Muite
• Morgan Hough (Intel related while testing SODECL on Intel NUCs)
• Tom Rix (Misc)
• Tim Flink
• Brian Lu
• Jonathan Steffan

Please add your name above if you want to help.

Tasks

• Package and make HC related projects more accessible to users (such as OpenCL, AMD's ROCm HIP, Intel oneAPI, SYCL, Vulkan, OpenGL, etc.)
• Document installation, packages, and general use cases
• Translation of wiki pages and documentation (if applicable)

AMD's ROCm (OpenCL/HIP)

HW Support

Upstream only officially supports x86_64, but they are open to pcc64le and arm64 patches

The ROCm packages in Fedora are built for all 64bit little endian systems (x86_64, arm64, ppc64le), but official support is for x86_64.

HW support is highly dependent on LLVM version included in Fedora, so if you have newer HW, you might need to wait for newer LLVM versions to be introduced to Fedora (usually in the spring and the autumn).

Note that your millage may vary, as pre vega HW on ROCm is experimental, missing functionality, and not guaranteed to work on all HW

Installation

Setup

To enable access to GPU resources for non-root users, the users must be added to the video or render group. The AMD ROCm Installation Guide (v5.2) and FAQs recommend the video group for all ROCm-supported operating systems.

Note:
The render group is only required for Ubuntu v20.04.

To add the current user to the video group:

   sudo usermod -a -G video $LOGNAME

To check for ROCm support of the running HW, you can install and run rocminfo:

   sudo dnf install rocminfo
   rocminfo

OpenCL

ROCm OpenCL can be installed with:

   sudo dnf install rocm-opencl

As well, rocm-clinfo or clinfo can be installed to verify it is working, e.g.:

   sudo dnf install rocm-clinfo
   rocm-clinfo

HIP

HIP is included in Fedora 39 and is pending for Fedora 38. For Fedora 38, you will need to add --enable-repo=updates-testing to dnf if it's not available yet.

Install with:

   sudo dnf install rocm-hip

For use with Blender, you might need to also install "rocm-hip-devel" if it does not detect HIP.

Intel

TODO: incomplete, take me!

Packages

Packages that use HC

Blender

Build with:

   rpmbuild --with rocm
