Formulas:
PMM read bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC0))*64.0/runtime
PMM read data volume [GBytes] = 1.0E-09*(SUM(MBOXxC0))*64.0
PMM write bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC1))*64.0/runtime
PMM write data volume [GBytes] = 1.0E-09*(SUM(MBOXxC1))*64.0
PMM bandwidth [MBytes/s] = 1.0E-06*(SUM(MBOXxC0)+SUM(MBOXxC1))*64.0/runtime
PMM data volume [GBytes] = 1.0E-09*(SUM(MBOXxC0)+SUM(MBOXxC1))*64.0

Profiling group to measure data rate and volume for accesses to Intel Optane DC
persistent memory. The Intel Optance DC devices are handled by the memory
controllers but require different events.
