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.

Intel Posts The "Last Part" To Their AMX Bring-Up For Linux

While for many years we have been accustomed to seeing Intel land their new hardware feature enablement work in the Linux kernel and related components well ahead of products shipping, occasionally there are lapses due to various internal and external timings. The launch of Sapphire Rapids is quickly approaching and one of the major additions is Advanced Matrix Extensions with its Linux support still being in the works.

An Early Look At The GCC 12 Compiler Performance On AMD Zen 3

GCC 12 isn't seeing its stable release until around March~April as usual, but with feature development slowly wrapping up as approaching the next stage of development next month to focus on fixes, recently I wrapped up some preliminary benchmarks for how GCC 12.0 is currently performing against GCC 11.2 on an AMD Ryzen 9 5950X (Zen 3) system.

It's been a half-year already since AMD introduced the EPYC 7003 "Milan" processors that continue performing well and gaining marketshare. While the recently released Ubuntu 21.10 is not a long-term support (LTS) release, for those wondering what this latest Linux distribution means for EPYC 7003 series performance, here is a look at its performance across many benchmarks against that of Ubuntu 21.04 that was released right after the Milan launch and then Ubuntu 20.04 as the current LTS stable series.
