Formulas:
Memory read bandwidth [MBytes/s] = 1.0E-06*(SUM(IMC_READS_NORMAL)+SUM(BYPASS_IMC_TAKEN))*64.0/time
Memory read data volume [GBytes] = 1.0E-09*(SUM(IMC_READS_NORMAL)+SUM(BYPASS_IMC_TAKEN))*64.0
Memory write bandwidth [MBytes/s] = 1.0E-06*(SUM(IMC_WRITES_ALL))*64.0/time
Memory write data volume [GBytes] = 1.0E-09*(SUM(IMC_WRITES_ALL))*64.0
Memory bandwidth [MBytes/s] = 1.0E-06*(SUM(IMC_READS_NORMAL) + SUM(BYPASS_IMC_TAKEN) + SUM(IMC_WRITES_ALL))*64.0/time
Memory data volume [GBytes] = 1.0E-09*(SUM(IMC_READS_NORMAL) + SUM(BYPASS_IMC_TAKEN) + SUM(IMC_WRITES_ALL))*64.0

This group derives the same metrics as the MEM group but use the events of the
Home Agent, a central unit that is responsible for the protocol side of memory
interactions.
