Name

liblgrp– locality group library

Synopsis

cc [ flag... ] file... -llgrp [ library... ]
#include <sys/lgrp_user.h>

Description

The functions in this library traverse the lgroup (locality group) hierarchy, discover its contents, and set a thread's affinity for an lgroup. A locality group represents the set of CPU-like and memory-like hardware devices that are at most some locality apart from each other.
