+# Short-Description: numad daemon recommends or binds workloads to NUMA nodes
+# 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.
