Linux Achieves 5.1M IOPS Per-Core With AMD Zen 3 + Intel Optane

Linux kernel developers have been working tirelessly to squeeze more performance out of IO_uring and the block / I/O code in general. IO_uring lead developer Jens Axboe who also serves as the Linux block subsystem's maintainer (among other roles and major contributions over the years) has used his system as a baseline for evaluating such kernel improvements. He's now moved to using AMD Zen 3 while sticking to Intel Optane storage and is seeing a mighty speed boost out of AMD's latest processors.

"Intel Software Defined Silicon" Coming To Linux For Activating Extra Licensed Hardware Features

There has been talk of Intel moving to offer more license-able/opt-in features for hardware capabilities found within a given processor as an upgrade. We are now seeing the Linux signs of that support coming with a driver for "Intel Software Defined Silicon" to allow for the secure activation of such features baked into the processor's silicon but only available as an up-charge option.

Facebook Has Been Working On BOLT'ing The Linux Kernel For Greater Performance

For several years now Facebook engineers have been working on BOLT as a way to speed-up Linux/ELF binaries. This "Binary Optimization and Layout Tool" is able to re-arrange executables once profiled to generate even faster performance than what can be achieved by a compiler's LTO and PGO optimizations. One of the latest BOLT efforts has been on optimizing the Linux kernel image.

Ampere Altra Max 128-Core CPU Is Priced Lower Than Flagship Xeon, EPYC CPUs

From our Ampere Altra Max M128-30 Linux performance preview earlier this week, one of the questions a number of readers were wondering about and a question I also still had open was on the Altra Max pricing... I've now received the current price list and actually comes in much lower than expected for a 128-core CPU in 2021.

IBM Proposing A CPU Namespace For The Linux Kernel

IBM engineer Pratik Sampat published an early prototype of a CPU namespace interface for the Linux kernel. This CPU namespace was devised to address coherency issues with current means of viewing available CPU resources as well as addressing possible security issues stemming from understanding resource access/positioning on the system.

Trying Out Ubuntu's New Flutter+Curtin-Powered Desktop Installer Was Disappointing

An effort going on for a while at Canonical has been to develop a new desktop installer for Ubuntu. With the recent Ubuntu 21.10 release they are still using their classic Ubiquity installer by default but have published a new preview build of Ubuntu 21.10 with their new desktop installer option. Here is a look at Ubuntu's forthcoming new installer.

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.
