Intel's Linux Software Optimizations Still Pay Off For Xeon 6700E "Sierra Forest" E-Core CPUs

When testing Intel's aggressive software Linux optimizations shipped by way of their in-house Clear Linux distribution, I am most often testing it on their high core count Xeon processors with AVX-512... Over the years in dozens of Phoronix articles there have been countless metrics showing off the out-of-the-box performance benefits from leveraging software built for higher x86_64 micro-architecture feature levels, employing compiler-based function multi-versioning, and the other extensive performance tuning carried out by Intel software engineers. But now with the Intel Xeon 6700E "Sierra Forest" series now being available for these all-E-core server processors, I was curious about quantifying the Clear Linux benefits over the likes of Ubuntu Linux. Here are those benchmarks for those curious about the difference.

Fedora 41 Installer Proceeding To Transition From X11 To Wayland App

With Fedora's new web-based installer UI being delayed to 2025 with Fedora 42, part of Red Hat's justification for that setback was needing to invest resources first in Fedora 41 by transitioning the OS installer to being a native Wayland application. The Fedora Engineering and Steering Committee (FESCo) has now signed off on that work as expected to make the Anaconda OS installer a native Wayland application...

Llamafile 0.8.7 Brings Fixes, Better ARM Performance & Preps For New Server

Llamafile has been one of the better new initiatives out of Mozilla in recent years. Llamafile makes it easy to conveniently distribute and run large language models as a single file while supporting both CPU and GPU execution and all-around making AI LLMs much more approachable for end-users. Out today is Llamafile 0.8.7 with more performance optimizations and new features...

Ubuntu 24.10 Now Defaults To Wayland On NVIDIA

With Ubuntu 24.10 due for release in October one of the expressed planned changes has been NVIDIA defaulting to using Wayland rather than X11 for the default desktop session. As of this past week the change is now in place for Ubuntu 24.10 daily users that will find Wayland-by-default when using the official NVIDIA Linux graphics driver...

Amazon Exploring MM-Local Memory Allocations To Help With Current/Future Speculation Attacks

Back in 2019 after various speculation-based CPU vulnerabilities began coming to light, Amazon engineers proposed process-local memory allocations for hiding KVM secrets. They were striving for an alternative mitigation for vulnerabilities like L1TF by essentially providing some memory regions for kernel allocations out of view/access from other kernel code. Amazon engineers this week laid out a new proposal after five years of ongoing Linux kernel improvements for MM-local memory allocations for dealing with current and future speculation-based cross-process attacks...
