While AMD EPYC processors offer phenomenal performance at the high-end for servers with up to 64 cores / 128 threads per socket, eight memory channels, and other features, not all server deployments call for such capabilities. In the lower-end dedicated web server rental space, budget web hosting, and similar personal / small office server space, AMD Ryzen processors can prove more than capable. Already some dedicated server providers are offering AMD Ryzen powered servers and more are expected to come soon -- especially with even more server-minded wares for Ryzen expected next generation. In looking at this space, we have been testing a number of AMD Ryzen processors recently compared to Intel Xeon E class competition for looking at the performance and value in the low-end dedicated server space.

Mesa has long had the OpenCL "Clover" Gallium3D state tracker that has supported OpenCL 1.x but lacked important extensions that impaired its practicality. With AMD backing their ROCm compute stack in more recent years and Intel going with their Compute-Runtime stack for oneAPI and OpenCL support, there also isn't a major backer to Clover besides Red Hat engineers and the community. Now though "Rusticl" has been published as a new Mesa OpenCL implementation written in the Rust programming language...

Back in late 2020 it was originally talked about for Canonical's effort around Snap packages to switch to LZO compression for faster start-up times. Today they published a new blog post on the Ubuntu site highlighting the Snap speed-ups while looking at KDE packages. The LZO-compressed packages are faster than XZ indeed, but still rather a lengthy start-up time for cold apps...

Published at the start of the new year was 2.3k patches providing "fast kernel headers" as a major speed-up to Linux kernel build times and addressing the dependency hell among all the header files in the Linux kernel source tree. It will likely take some time for that massive patch series to work its way to mainline in full, but at least for Linux 5.18 already the patches touching the kernel's scheduler area are ready to land...

Earlier this month AMD began publishing code for their "GFX940" graphics block as a new CDNA GPU, presumably what will be the AMD Instinct MI300 series as their next-gen datacenter GPU. More GFX940 open-source driver enablement work is getting underway...

While there have already been a number of vulnerabilities exhibited for Intel's Software Guard Extensions (SGX) from Prime+Probe to Plundervolt, Spectre-like attacks, SGAxe, and others, it looks like they expect more still to come in the future. Intel engineers are working on the ability for SGX to gracefully handle live CPU microcode updates without a reboot, which these days is increasingly driven for security mitigations and system administrators wanting to apply said updates right away while foregoing downtime...

It's been nearly one year since Microsoft published CBL-Mariner 1.0 as their internal Linux distribution in use at the WIndows company.
