How do I isolate cores in Linux?
Isolating CPUs generally involves:
- removing all user-space threads;
- removing any unbound kernel threads (bound kernel threads are tied to a specific CPU and may not be moved);
- removing interrupts by modifying the /proc/irq/N/smp_affinity property of each Interrupt Request (IRQ) number N in the system.
