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

Profiling group to measure memory bandwidth drawn by all cores of a socket.
Since this group is based on Uncore events it is only possible to measure on a
per socket base. Some of the counters may not be available on your system.
Also outputs total data volume transferred from main memory.
