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)
• Tom Rix (CUDA, OpenCL, Vulkan Compute, Misc)
• Tim Flink

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 (note this is no longer required for rocm-opencl-5.2.1-2 or later):

   export ROC_ENABLE_PRE_VEGA=1

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 (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!
