Description
lgrpinfo prints information about the locality group (lgroup)
hierarchy and its contents.
An lgroup represents the set of CPU and memory-like hardware devices
that are at most some distance (latency) apart from each other. All
lgroups in the system are identified by a unique integer called an
lgroup ID.
lgroups are organized into a hierarchy to facilitate finding the
nearest resources. Leaf lgroups each contain a set of resources that
are closest (local) to each other. Each parent lgroup in the
hierarchy contains the resources of its child lgroups plus their
next nearest resources. Finally, the root lgroup contains all the
resources in the domain within the largest latency.
A Uniform Memory Access (UMA) machine is simply represented by the
root lgroup. A Non Uniform Memory Access (NUMA) machine is
represented by a hierarchy of lgroups to show the corresponding
levels of locality. For example, a NUMA machine with two latencies
(local and remote) has an lgroup hierarchy consisting of two levels
with its leaves and the root.
