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.
How do you isolate a CPU?
1. In kernel boot options we can provide kernel boot parameter. “ isolcpus= ‘CPU Number‘ ” In grub config we can mention this boot parameter. To update grub config mention this parameter in file “/etc/default/grub” mention parameter as isolcpus=2 in front of GRUB_CMDLINE_LINUX which says isolate cpu number 2.
