  • Intel ISPC Compiler Lands GPU Code Generation Support

    Intel's open-source ISPC (the Intel SPMD Program Compiler) now has preliminary support for code generation targeting their GPUs.

    The Intel SPMD Program Compiler that is focused on C programming with extensions around single program, multiple data programming concepts for leveraging SSE and AVX is now seeing initial support for exploiting the potential of Intel graphics processors.

    ISPC has long worked well for exploiting the potential of AVX/AVX2 and AVX-512 as well as SSE4 while now this SPMD program compiler can begin targeting Intel Gen/Xe Graphics.

    The ISPC support relies upon Intel's oneAPI Level Zero for managing devices and other orchestration.

  • AMD's ROCm AOMP Compiler 11.7-1 Brings OMPD Support, ROCgdb

    The AMD ROCm developer tool engineers have released a new build of AOMP, their LLVM Clang compiler downstream that adds OpenMP support for Radeon GPU offloading until that support ultimately makes it back upstream into LLVM/Clang.

    The ROCm engineers working on AOMP have been doing a great job on keeping their code re-based against the newest upstream LLVM code, which with this release is from just two weeks ago prior to the LLVM 11.0 branching. The AMD developers have been working on upstreaming more of their LLVM/Clang changes albeit that is a lengthy process especially with new Radeon OpenMP code continuing to be written and fine tuned.

Plasma and the systemd startup

Landing in master, plasma has an optional new startup method to launch and manage all our KDE/Plasma services via a system --user interface rather than the current boot scripts. This will be available in Plasma 5.21. It is currently opt-in, off by default. I hope to make it the default where available after more testing and feedback, but it is important to stress that the current boot-up method will exist and be supported into the future. A lot of work was put into splitting and tidying so the actual amount of duplication in the end result is quite small and manageable. Read more

Mozilla Thunderbird 78.3 Is Out and You Can Finally Upgrade from Earlier Versions

Mozilla Thunderbird 78.3 open-source and free email client has arrived with more improvements and bug fixes, and you can now finally upgrade from older Thunderbird releases. When Thunderbird 78 launched earlier this year, it didn’t support automatic upgrades from version 68 or earlier. Automatic upgrade was blocked intentionally due to the revamped extension system that only supports MailExtensions, not classic extensions, to no break your Thunderbird installations. Three months later, Mozilla enabled automatic upgrades in Thunderbird with version 78.2.2 released a couple of weeks ago. Now Thunderbird 78.3 is out and it disables the installation of “legacy” MailExtensions. Read more
