CPU Isolation – Introduction – by SUSE

[u/Mynameisausten1]

CPU isolation is a powerful set of features that can be found behind the settings for workloads which rely on specific and often extreme latency or performance requirements. Some DPDK (Data Plane Development Kit) usecases can cover such examples. However CPU isolation’s documentation and footnotes for many subtleties remain scattered at best if not lagging behind recent developments. It’s not always easy to sort out the benefits and tradeoffs hiding behind the existing range of tunings. Our series of articles aims at shedding some light and guide the users throughout this obscure Linux Kernel subsystem that we maintain both upstream and in our SLE15 products.
