👁 Llama.cpp benchmark with settings of Backend: CPU BLAS, Model: granite-3.0-3b-a800m-instruct-Q8_0, Test: Prompt Processing 512. Linux 6.18-rc7 was the fastest.

👁 BRL-CAD benchmark with settings of VGR Performance Metric. Linux 6.18-rc7 was the fastest.

There was occasionally a performance regression but for the most part was a win for performance.

👁 Stress-NG benchmark with settings of Test: Socket Activity. Cache Aware Sched v2 was the fastest.

👁 Llama.cpp benchmark with settings of Backend: CPU BLAS, Model: gpt-oss-20b-Q8_0, Test: Prompt Processing 512. Cache Aware Sched v2 was the fastest.

👁 Llama.cpp benchmark with settings of Backend: CPU BLAS, Model: granite-3.0-3b-a800m-instruct-Q8_0, Test: Text Generation 128. Cache Aware Sched v2 was the fastest.

Overall this initial testing of Cache Aware Scheduling on Intel Xeon 6P "Granite Rapids" was working out quite well. Similar to the Cache Aware Scheduling tests on 5th Gen AMD EPYC "Turin", for Granite Rapids there were also some decent performance advantages spotted from this proposed Linux kernel code.

👁 Geometric Mean Of All Test Results benchmark with settings of Result Composite, Intel Xeon 6P Cache Aware Scheduling Benchmarks. Cache Aware Sched v2 was the fastest.

Cache Aware Scheduling wasn't submitted for the current Linux 6.19 kernel cycle but here's to hoping that it will cross the finish line in 2026 for benefiting modern Linux systems with multiple cache domains.
