Blender's Cycles engine is celebrating its tenth birthday today and in marking the occasion, the Blender project has announced the ongoing work on "Cycles X" as what started as a research project in preparing this engine for the next ten years. It's a big step forward for Cycles but with Cycles X the OpenCL rendering kernels are being removed...

As we have been showing in a few articles already, Ubuntu 21.04 is in good shape performance-wise and generally coming ahead of Ubuntu 20.10 and 20.04 LTS. We've seen that on a number of systems in the lab, but how does this better performance out of Ubuntu 21.04 compare to say Intel's Clear Linux? Here are some benchmarks.

Earlier this week was a surprising Linux kernel networking commit that removed an IBM engineer as one of the driver maintainers for the IBM Power SR-IOV Virtual NIC driver. Seemingly at issue with this VNIC driver work was the developer using his personal email address in working on the driver in his off-hours. IBM has now clarified their stance on such work...

The P-State and CPUFreq "performance" governors on Linux with desktop Intel/AMD processors can be of help for gaming and other select workloads by tending to keep the CPU clock frequencies higher than the default ondemand (CPUFreq) or powersave (P-State) governors used by nearly all Linux distributions. But with Intel's new Core i9 11900K "Rocket Lake" is a dramatic difference in power and performance between the Intel P-State performance and powersave governors than what we have seen over the years with prior generations of Intel Core processors.

Ubuntu 21.04 "Hirsute Hippo" is now available...

Tomorrow's release of Ubuntu 21.04 is exciting on the desktop for Wayland by default in supported configurations and many other package updates and enhancements. But even for being a non-LTS release if you are interested in running Ubuntu Server there are some performance improvements to enjoy with newer platforms. Here is a look at the AMD EPYC 7003 "Milan" performance across Ubuntu 20.04 LTS, 20.10, and 21.04 with an AMD EPYC 7763 Supermicro server.

It's fairly common that many longtime Linux kernel developers use their personal email addresses for signing off on kernel patches or dealing with other patch work, especially when they are engaging with kernel development in their personal time too and occasionally jumping between employers over time while still sticking to interacting with the upstream kernel community, etc. There are also understandably some companies that mandate the use of their corporate email addresses for their official work/patches while now IBM seems to be taking things one step to the extreme...

One of the exciting elements of last month's AMD EPYC 7003 "Milan" series launch was having same-day availability in public clouds. Microsoft as one of AMD's cloud partners worked closely to deliver launch-day availability in their public cloud using EPYC 7003 series processors with the new "HBv3" instances focused on high performance computing (HPC) virtual machines. Here are some benchmarks of the Azure HPv3 instances compared to prior generation Microsoft Azure HPC instances available on-demand in their cloud.
