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.
