Code to help with NUMA opts

numa_ops.cpp

// Numa allocate
void numa_alloc(double* data) {
  data = static_cast<double*>(numa_alloc_onnode(data_size, node_id));
}

// Numa deallocate
void numa_dealloc(double* data, size_t data_size) {
  numa_free(data, data_size);
}

// Bind to node(Call within ctor for launched thread)
void bind2node_id(id) {
    struct bitmask *bmp = numa_allocate_nodemask();
    numa_bitmask_setbit(bmp, id);
    numa_bind(bmp);
    numa_free_nodemask(bmp);
}
