Radeon ROCm Updates Documentation Reinforcing Focus On Headless, Non-GUI Workloads - Phoronix
The Radeon ROCm open-source compute documentation has been updated to more clearly spell out what was already implied: their focus is on compute for headless, GUI-less workloads and not OpenCL or compute for conventional desktop applications.
Added last week to the main README file on the ROCm repository is a notice that the AMD ROCm platform is intended as a "compute stack for headless system deployments" and not focused on GUI-based software applications. This doesn't appear to be a change in policy but just making it clear that their focus is on HPC and other headless deployments -- not necessarily on allowing you to have a nice OpenCL compute stack for the likes of Blender, Darktable, DaVinci Resolve, and other OpenCL-using GUI desktop programs.

Vulkan 1.2.171 Released With New Extension For BlackBerry QNX Support - Phoronix
Vulkan 1.2.171 is out this morning with several fixes and clarifications to this high performance graphics / compute API specification while there is also a new extension for allowing BlackBerry QNX support.
As reported on Phoronix back in January, BlackBerry was working to bring Vulkan to QNX. That tentative extension reserved back in January, VK_QNX_screen_surface, is now formally added to the Vulkan specification.

There's Finally An Easy Way To Track Mesa's OpenCL Support - Phoronix
Hitting Mesa 21.1-devel this weekend is finally the OpenCL status reporting to the features documentation (docs/features.txt). The OpenCL status reporting is done in a similar manner to the Vulkan and OpenGL extension/version reporting, which makes it now quite easy and quick to check on the current Mesa OpenCL status.
The current Mesa features reporting can be seen via the Git interface. Or more easily is MesaMatrix.net that tracks the Mesa Git features.txt in a nice, HTML'ed interface.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
