+Maximum memory bandwidth supported on each numa node. It makes use of a

+The node_num must match with any node in sysfs/devices/system/node directory.
+And, the bandwidth is expressed in terms of MBps. This config file should be
+filled up manually after running some bandwidth saturation benchmark tools.
