Isolating a CPU prevents tasks/processes from being assigned to or from the CPU by the scheduler and therefore. assigning processes/tasks to or from the CPU must be done manually via the taskset, cset commands, or other. software utilizing the CPU affinity syscalls.

CPU pinning hauv Linux yog dab tsi?
Processor affinity, or CPU pinning or “cache affinity”, enables the binding and unbinding of a process or a thread to a central processing unit (CPU) or a range of CPUs, so that the process or thread will execute only on the designated CPU or CPUs rather than any CPU.

CPU tuaj yeem muaj pes tsawg cores?
Today, CPUs have been two and 18 cores, each of which can work on a different task. As you can see in our CPU Benchmarks Hierarchy, that can have a huge impact on performance. A core can work on one task, while another core works a different task, so the more cores a CPU has, the more efficient it is.
