Last November AMD introduced the first of the 4th Gen EPYC series with the EPYC 9004 "Genoa" processors and that was then complemented earlier this year by the July launch of the Genoa-X processors for sporting AMD 3D V-Cache to help technical computing workloads and as well launching Bergamo for the Zen 4C based processor designs that allow up to 128 cores / 256 threads per socket. While AMD has a very robust portfolio for the high-end server space with 4th Gen EPYC, today AMD is introducing the EPYC 8004 "Siena" processors for "intelligent edge" servers. Siena is a step below Genoa but still very capable offering and coming in at a lower price point while being geared more for maximizing power efficiency and opening up EPYC to more deployments outside of the data center.

Stemming from Intel engineers finding significant overhead in some Linux scheduler functions when running PostgreSQL within a Docker instance, a new scheduler patch is on the way for Linux 6.7 that will help out at least Ice Lake and Sapphire Rapids with some migration-heavy workloads. With the change being in the common scheduler code, it's also likely to help out other hardware platforms too...

Since 2021 the Itanium IA-64 code was orphaned in the Linux kernel and over the course of this year there's been talk of retiring the Itanium code from the kernel, a.k.a. strip it out. It looks like 2023 will end with the Itanium IA-64 code indeed being removed from the Linux kernel...
