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.
