Merged for Linux 6.18 was a new feature called Sheaves as an opt-in, per-CPU array-based caching layer. Plus there is a per-NUMA-node cache of Sheaves called a "Barn". In continuing to build out the Linux kernel usage of Sheaves, a set of initial patches were posted this week to replace the CPU slabs with Sheaves within the slub allocator code...

One way AI can improve on human work Computer scientists at UC Berkeley say that AI models show promise as a way to discover and optimize algorithms.…

With Amazon recently launching their M8a AWS instances powered by 5th Gen AMD EPYC "Turin", for their M8 class instance types there now are all the latest-generation CPU options with AMD EPYC Turin (M8a), Intel Xeon 6 Granite Rapids (M8i), and their in-house Graviton4 processors (M8g). After recently looking at the M7a vs. M8a performance with Amazon EC2, many Phoronix readers expressed interest in seeing an M8a vs. M8i vs. M8g performance showdown so here are those benchmarks.

It's been rare in recent years seeing any new OpenGL extensions given the wild success these days of the Vulkan API with its vast hardware adoption and increasing software support around that modern graphics and compute API. Yet this October has been unusual with now seeing multiple new OpenGL extensions merged to the OpenGL registry...

A minimal KDE Plasma 6 setup that’s effortless to build and customize. Combining Utterly Nord’s elegance with natural anime-inspired visuals, this desktop brings clarity and balance. Menus and widgets are adjusted for a smooth, clean

GTK has long supported Scalable Vector Graphics (SVG) for icons but with up until recently relying on the external librsvg library, the integration hasn't been perfect. But Red Hat engineer Matthias Clasen has been working on having the GTK toolkit natively support SVG...

Modern computing systems rely heavily on operating-system schedulers to allocate CPU time fairly and efficiently. Yet many of these schedulers operate blindly with respect to the meaning of workloads: they cannot distinguish, for example, whether a task is latency-sensitive or batch-oriented. This mismatch, between application semantics and scheduler heuristics, is often referred to as the semantic gap. A recent research framework called SchedCP aims to close that gap.

The past number of months has seen a lot of work by Intel Linux kernel engineers on cache-aware scheduling / load balancing for helping modern CPUs that have multiple caches. With cache aware scheduling, tasks that will likely share resources could be aggregated into the same cache domain to enjoy better cache locality. With the cache aware scheduling patches recently updated and now working past the "request for comments" stage, I was eager to try out these new patches. Especially with a 44% time reduction reported for one of the benchmarks, I was eager to run some tests and the first of those results are being shared today.

We apologize for the impact this event caused our customers. While we have a strong track record of operating our services with the highest levels of availability, we know how critical our services are to our customers, their applications and end users, and their businesses.

In the world of modern CPUs, speculative execution, where a processor guesses ahead on branches and executes instructions before the actual code path is confirmed, has long been recognized as a performance booster. However, it has also given rise to a class of vulnerabilities collectively known as “Spectre” attacks, where microarchitectural side states (such as the branch target buffer, caches, or predictor state) are mis-exploited to leak sensitive data.

Back in May AMD announced the Radeon AI PRO R9700 with 128 AI accelerators, 32GB of GDDR6 video memory, and other advantages for this AI-focused RDNA4 based graphics card over the RDNA3-based Radeon PRO W7900. The Radeon AI PRO R9700 was supposed to be available in July while today AMD announced it will be going on sale next week...
