More importantly though: use isolcpus= on the kernel cmdline to make sure the kernel will never schedule its own work on the CPUs you want to exclusively assing to a specific set of units. Make sure with /proc/interrupts and /proc/irq that all IRQs are properly dispatched only on the CPUs you don't want your own stuff to run.
