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.

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)

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)

Package status

Below is a list of ROCm packages with their status. If something isn't packaged in Fedora or EPEL, feel free to take it!

This reference might be helpful for those attempting to package: https://gist.github.com/cgmb/edb7b790ab55681fb2ba5385ee02489b

opencl-icd-loader			rocm-ocl-icd	https://github.com/KhronosGroup/OpenCL-ICD-Loader	Fedora already has ocl-icd, but the khronos version is required for GL-CL interop support
rocm-opencl-runtime	In Testing (F36/EL8/EL9)		rocm-opencl	https://github.com/radeonopencompute/rocm-opencl-runtime	F36: https://bodhi.fedoraproject.org/updates/FEDORA-2022-2cee071a16
rocm_smi_lib	See notes		rocm-smi-lib	https://github.com/radeonopencompute/rocm_smi_lib	The deprecated rocm-smi should be replaced by this
hip			hip-[runtime,devel,docs,samples]	https://github.com/rocm-developer-tools/HIP	Upstream doesn't cleanly separate the cmake logic with hipamd, we should send upstream patches
hipamd			rocm-hip-runtime	https://github.com/rocm-developer-tools/hipamd	Upstream wants to merge this with OpenCL's sources, so it might be worth waiting to package, or adding as a subpackage for rocm-opencl. Testing version in mystro256's COPR: https://copr.fedorainfracloud.org/coprs/mystro256/rocm-hip/ using rocm-hip to avoid amd branding in Fedora package name.

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.

Most products starting with vega 10 (Radeon RX Vega) should work without configuration, but any pre-vega HW, such as the RX 400's or 500's, will require setting:

   export ROC_ENABLE_PRE_VEGA=1

To enable experimental support for older 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 (Fedora 36, EPEL8, and EPEL9 are currently in testing):

   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

TODO

Some experimental builds exist here (use at your own risk): https://copr.fedorainfracloud.org/coprs/mystro256/rocm-hip/

Intel

TODO: incomplete, take me!
