static int | hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset, cpu_set_t *schedset, size_t schedsetsize) |
static int | hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t topology, hwloc_cpuset_t hwlocset, const cpu_set_t *schedset, size_t schedsetsize) |
This interface offers ways to convert between hwloc cpusets and glibc cpusets such as those manipulated by sched_getaffinity() or pthread_attr_setaffinity_np().
topology
must match the current machine. static int hwloc_cpuset_from_glibc_sched_affinity | ( | hwloc_topology_t | topology, |
hwloc_cpuset_t | hwlocset, | ||
const cpu_set_t * | schedset, | ||
size_t | schedsetsize | ||
) | [inline, static] |
Convert glibc sched affinity CPU set schedset
into hwloc CPU set.
This function may be used before calling sched_setaffinity or any other function that takes a cpu_set_t as input parameter.
schedsetsize
should be sizeof(cpu_set_t) unless schedset
was dynamically allocated with CPU_ALLOC
