Dynamic CPU Management in Linux

A new patch series for the Linux kernel, called Dynamic Housekeeping and Enhanced Isolation (DHEI), is under evaluation. This initiative aims to provide run-time adjustments to kernel behavior regarding CPU isolation, with the goal of supporting latency-sensitive tasks.

The stated goal is to assist cloud-native orchestrators and high-frequency trading platforms in dynamically re-partitioning CPU resources without causing downtime. This approach would allow for greater flexibility and responsiveness in the allocation of computing resources, optimizing performance and reducing operating costs.

For those evaluating on-premise deployments, there are trade-offs to consider carefully. AI-RADAR offers analytical frameworks on /llm-onpremise to evaluate these aspects.
