It is used to track memory bandwidth usage for a specific task, or group of tasks. Memory Bandwidth Monitoring is an extension of the existing Cache QoS Monitoring (CQM) feature found in Haswell server. The mechanism used is the same, where tasks are associated with an Resource Monitoring ID (RMID), which the CPU uses to track the bandwidth usage.
