NAME

hwlocality_glibc_sched - Interoperability with glibc sched affinity

    Functions

    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)

CONTENTS

Detailed Description

This interface offers ways to convert between hwloc cpusets and glibc cpusets such as those manipulated by sched_getaffinity() or pthread_attr_setaffinity_np().

Note:

Topology topology must match the current machine.

Function Documentation

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

static int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset, cpu_set_t * schedset, size_t schedsetsize) [inline], [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
