%description
numad is a userspace daemon that monitors NUMA usage and resource usage
and attempts to configure workloads using cpusets to use a subset of
CPUs and memory nodes to maximise the number local memory access for
best performance. Alternatively, it can be used to give hints as to how
workloads should be manually bound to CPUs and memory nodes. This daemon
is primarily intended for scenarios where there are multiple processes
each which fit within a NUMA node. Examples of such configurations are
virtual machine instances where each VM is smaller than a NUMA node
or running multiple JVMs where each instance fits within a NUMA node.
If the workload is one process that spans two or more nodes such as
a large database server or a single JVM instance then numad is likely
to regress performance.
