Set the default memory binding policy of the current process or thread to prefer the
NUMA node(s) near the specified cpuset.
What does "nodes near the specified cpuset" means? The node wherethe specified cpuset lives? Or others node?
What this function does in particular?
I'm calling hwloc_set_membind from two OpenMP threads passing HWLOC_MEMBIND_BIND policy.
The first thread allocates with a malloc an array. The second thread (bound on other node) initialize the array.
The free memory on the nodes decrease only on the node where the second thread is. Is it rigth?
hwloc_set_membind involves all future allocations?
Thanks in forward.
