Intel AMX Support Appears Ready For Linux 5.16

It's been over one year since Intel disclosed Advanced Matrix Extensions and began posting patches for bringing up AMX support under Linux in anticipation of Xeon Scalable "Sapphire Rapids" processors. While the compiler-side work to GCC and LLVM/Clang has been landing, finally with the forthcoming Linux 5.16 cycle that AMX support appears ready for landing.

Intel Core i9 11900K: Five Linux Distros Show Sizable Lead Over Windows 11

Now that Windows 11 has been out as stable and the initial round of updates coming out, I've been running fresh Windows 11 vs. Linux benchmarks for seeing how Microsoft's latest operating system release compares to the fresh batch of Linux distributions. First up is the fresh look at the Windows 11 vs. Linux performance on an Intel Core i9 11900K Rocket Lake system.

Newest Linux Optimizations Can Achieve 10M IOPS Per-Core With IO_uring

Just one week ago Linux block subsystem maintainer Jens Axboe was optimizing the kernel to get 8 million IOPS on a single CPU core. He progressed the week hitting around ~8.9M IOPS per-core and began to think he was hitting the hardware limits and running out of possible optimizations. However, this week he is kicking things off by managing to hit 10 million IOPS!

Dynatron A39 - A Good Heatsink For Threadripper/EPYC 4U Systems

Quietly released earlier this year was the Dynatron A39 heatsink that is capable of up to 280 Watts heat dissipation for satisfying even the very latest, high-end AMD EPYC 7003 "Milan" processors. This Dynatron A39 TR4/sTRX4/SP3 heatsink has been working out very well for those needing to cool a Threadripper/EPYC system in a 3U or larger enclosure.

Google Continues Work On User-Managed Concurrency Groups For Linux

Earlier this year was news that Google is finally working to open-source their Fibers user-space scheduling framework. For the better part of the past decade they have been developing this user-space scheduling framework and finally now are working on offering public, open-source code intended for upstream around their work.
