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.
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
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
