Re: [hwloc-users] Multiple thread binding

Ok, and in this way are equivalent? #pragma omp parallel num_threads(1) { hwloc_obj_t core = hwloc_get_obj_by_type(*topology, HWLOC_OBJ_PU, 0); hwloc_cpuset_t set = hwloc_bitmap_dup(core->cpuset); hwloc_set_cpubind(*topology, set, HWLOC_CPUBIND_THREAD | HWLOC_CPUBIND_STRICT);

Re: [hwloc-users] Multiple thread binding

Mm, i'm not sure. Suppose this: $pragma omp parallel num_thread(1) { hwloc_set_cpubind(*topology, set, HWLOC_CPUBIND_THREAD | HWLOC_CPUBIND_STRICT | HWLOC_CPUBIND_NOMEMBIND); } is equivalent to? $pragma omp parallel num_thread(1) { hwloc_set_cpubind(*topology, set, HWLOC_CPUBIND_THREAD);

[hwloc-users] Multiple thread binding

Dear all, binding a thread on a core like this: hwloc_set_cpubind(*topology, set, HWLOC_CPUBIND_THREAD | HWLOC_CPUBIND_STRICT | HWLOC_CPUBIND_NOMEMBIND); is it possible do multiple call to hwloc_set_cpubind passing each flag per time? hwloc_set_cpubind(*topology, set,
