Later this week it looks like the latest round of Cache Aware Scheduling fixes will be merged for enhancing this kernel scheduler functionality for grouping related tasks together on CPU cores that share the same last level cache (LLC).
These fixes aim to improve the efficiency of CPU resource allocation by ensuring that related tasks run on cores that can share data more effectively. This can lead to performance gains in applications that are sensitive to cache performance. The backporting to the previous kernel version allows users still on Linux 7.2 to benefit from these improvements.

Cache Aware Scheduling aims to improve task grouping on CPU cores with shared cache.
The upcoming fixes will be included in the Linux 7.3 kernel and backported to 7.2.
Enhanced cache locality can lead to performance improvements for certain workloads.
THE READ
What the cluster adds up to.
The inclusion of Cache Aware Scheduling fixes in Linux 7.3 signifies a focused effort to optimize the kernel's scheduling algorithm, particularly in relation to cache efficiency. By grouping tasks that share the same last level cache (LLC), the system can minimize cache misses, which is crucial for performance in data-intensive applications.
The backporting of these fixes to Linux 7.2 ensures that users who have not yet upgraded to the latest kernel can still take advantage of these performance improvements. This is particularly relevant for enterprise environments where stability and long-term support for existing systems are prioritized over the latest features.
It is important to note, however, that the effectiveness of these scheduling fixes may diminish in scenarios where CPU cores do not share LLC or in highly threaded applications that do not benefit from localized cache access. This means that while many applications may see improvements, some workloads may not experience significant changes.
