For those building your own server around the new Intel Xeon 6 "Granite Rapids" or AMD EPYC 9005 "Turin" platforms and using DDR5-6000/DDR5-6400 memory (or the interesting MRDIMM-8000 memory with Xeon 6 P), one of the factors you need to be much more mindful about than in the past is that at least the initial generation of DDR5-6000+ memory is running much hotter than prior server memory. There's been guidance from Intel and AMD as well as sever vendors about the thermal considerations with DDR5-6000/DDR5-6400 and extra precautions. Here's a look at the DDR5-6000 thermals on a recent AMD EPYC 9655 Turin server build and then taming the DDR5 server memory modules using Corsair Vengeance Airflow Memory Cooling Fans.

In today's article is exploring how the Xe2 Lunar Lake graphics is performing for OpenCL / GPU compute relative to the prior Meteor Lake Arc Graphics that were already a nice step-up over earlier Intel integrated graphics.

With GIMP 3.0-RC1 out for testing since earlier this month, the hope is that GIMP 3.0 stable will in fact ship in time for the release of Ubuntu 25.04 next April.

While the end of year holidays are fast approaching, my commitment to Linux hardware and open-source software remains and there still is a lot of interesting content to come this year still -- each and every day, without change for roughly a decade. Unfortunately though due to the (sad) state of the ad industry, many major companies focusing on the likes of Facebook/Meta ads, and the frequent use of ad-blockers by Linux/FLOSS readers make ongoing operations increasingly difficult. But if you'd like to show some love this holiday season, the Phoronix Premium "Cyber Week" / "Black Friday" special is now taking place so you can enjoy the site ad-free, native dark mode support, multi-page articles on a single page, and other benefits while hopefully allowing the site to continue for years to come...

Huawei engineer Zhang Yi posted a set of nine patches today for enabling large folio support for regular files with the EXT4 file-system. These patches enable large folios for EXT4 on regular files except when using FSVERITY, FSCRYPT, or the journaled data mode. Long story short, these large folio patches can deliver some nice performance gains for both reads and writes...

Sent out last night for the ongoing Linux 6.13 merge window were all of the perf tool changes for the wonderful "perf" subsystem for performance profiling and the like.
