- Cache Aware Scheduling aims to improve Linux performance on CPUs with multiple cache domains by keeping tasks that share data within the same last level cache (LLC) domain to enhance cache locality and reduce cache misses.
- Recent benchmarks were conducted on an AMD Ryzen Threadripper 9980X system, showing positive results for this feature, which is expected to be included in Linux 7.2.
- The testing involved turning Cache Aware Scheduling on and off using runtime controls on a custom Linux kernel based on 7.1-rc2, with Ubuntu 26.04 as the operating system.
- Previous tests on AMD EPYC Turin and Intel Xeon 6 also demonstrated success, indicating broad applicability across modern AMD and Intel processors.
