Python pick_cpu Examples

Example #1

File: vdsmd.py Project: kkoojjyy/vdsm

def __set_cpu_affinity():
    cpu_affinity = config.get('vars', 'cpu_affinity')
    if cpu_affinity == "":
        return

    online_cpus = taskset.online_cpus()

    log = logging.getLogger('vds')

    if len(online_cpus) == 1:
        log.debug('Only one cpu detected: affinity disabled')
        return

    if cpu_affinity.lower() == taskset.AUTOMATIC:
        cpu_set = frozenset((taskset.pick_cpu(online_cpus), ))
    else:
        cpu_set = frozenset(
            int(cpu.strip()) for cpu in cpu_affinity.split(","))

    log.info('VDSM will run with cpu affinity: %s', cpu_set)
    taskset.set(os.getpid(), cpu_set, all_tasks=True)
