For example, let's say I have an 8 core CPU with dual hyper-threading, which results in 16 vcpus. CPU core isolation ensures that the kernel processes scheduler will not interact with those CPU Sep 29, 2023 · Verify Affinity: Within your program, you can also explicitly set CPU affinity for your threads to the CPU cores within your specified list using functions like pthread_setaffinity_np (in the case of POSIX threads) or platform-specific API calls. Tuna can be used to isolate a cpu core and it dynamically moves processes run in that particular cpu to neighboring cpu. Under normal circumstances, the kernel task scheduler will treat all CPUs as available for scheduling process threads and regularly preempts executing process threads to give CPU time to other applications.
