NAME
hwlocality_glibc_sched - Interoperability with glibc sched affinity
SYNOPSIS
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)
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
