hwlocality_glibc_sched(3) Library Functions Manual hwlocality_glibc_sched(3) NAME hwlocality_glibc_sched - Interoperability with glibc sched affinity SYNOPSIS Functions int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset, cpu_set_t *schedset, size_t schedset- size) int hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t topology, hwloc_cpuset_t hwlocset, const cpu_set_t *schedset, size_t schedset- size) 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 int hwloc_cpuset_from_glibc_sched_affinity (hwloc_topology_t topology, hwloc_cpuset_t hwlocset, const cpu_set_t * schedset, size_t schedsetsize) [inline] 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 Returns 0 on success. -1 with errno set to ENOMEM if some internal reallocation failed. int hwloc_cpuset_to_glibc_sched_affinity (hwloc_topology_t topology, hwloc_const_cpuset_t hwlocset, cpu_set_t * schedset, size_t schedsetsize) [inline] 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 Returns 0.
