Helpers for manipulating glibc sched affinity

Functions

static inline void hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_cpuset_t hwlocset, cpu_set_t *schedset, size_t schedsetsize)
 Convert hwloc CPU set toposet into glibc sched affinity CPU set schedset.
static inline hwloc_cpuset_t hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t topology, const cpu_set_t *schedset, size_t schedsetsize)

Function Documentation

static inline hwloc_cpuset_t hwloc_cpuset_from_glibc_sched_affinity ( hwloc_topology_t  topology,
const cpu_set_t *  schedset,
size_t  schedsetsize 
) [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

hwloc_cpuset_t  hwlocset,
cpu_set_t *  schedset,
size_t  schedsetsize 
) [static]

Convert hwloc CPU set toposet into glibc sched affinity CPU set schedset.

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
