C++ (Cpp) numa_bind Examples

Example #1

File: common.cpp Project: zheng-da/FlashX

void bind2node_id(int node_id)
{
	struct bitmask *bmp = numa_allocate_nodemask();
	numa_bitmask_setbit(bmp, node_id);
	numa_bind(bmp);
	numa_free_nodemask(bmp);
}

Example #2

File: bind_cpu.c Project: kjseefried/psim2.X

int bind_cpu(int cpu) {
	struct bitmask *nodemask =  numa_parse_nodestring("0");
	struct bitmask *cpumask = numa_allocate_cpumask();

	numa_bind(nodemask);
	cpumask = numa_bitmask_clearall(cpumask);
	return numa_sched_setaffinity( getpid(), numa_bitmask_setbit(cpumask, cpu-1) );
}

Example #3

File: pfutils.c Project: GreggIndustries/PF_RING

int bind2node(int core_id) {
  char node_str[8];

  if (core_id < 0 || numa_available() == -1)
    return -1;

  snprintf(node_str, sizeof(node_str), "%u", numa_node_of_cpu(core_id));
  numa_bind(numa_parse_nodestring(node_str));

  return 0;
}

Example #4

File: numa_node_size.c Project: 1587/ltp

int main(void)
{
#if HAVE_NUMA_H
	nodemask_t nodemask;
	void hardware();
	if (numa_available() < 0) {
		printf("This system does not support NUMA policy\n");
		numa_error("numa_available");
		numa_exit_on_error = 1;
		exit(numa_exit_on_error);
	}
	nodemask_zero(&nodemask);
	nodemask_set(&nodemask, 1);
	numa_bind(&nodemask);
	hardware();
	return numa_exit_on_error;
#else
	printf("NUMA is not available\n");
	return 1;
#endif
