EVENTSET
UPMC0  UNC_DRAM_ACCESSES_DCT0_ALL
UPMC1  UNC_DRAM_ACCESSES_DCT1_ALL

METRICS
Runtime (RDTSC) [s] time
Memory bandwidth [MBytes/s]   1.0E-06*(UPMC0+UPMC1)*64.0/time
Memory data volume [GBytes]   1.0E-09*(UPMC0+UPMC1)*64.0

LONG
Formulas:
Memory bandwidth [MBytes/s] = 1.0E-06*(DRAM_ACCESSES_DCTO_ALL+DRAM_ACCESSES_DCT1_ALL)*64/time
Memory data volume [GBytes] = 1.0E-09*(DRAM_ACCESSES_DCTO_ALL+DRAM_ACCESSES_DCT1_ALL)*64
-
Profiling group to measure memory bandwidth drawn by all cores of a socket.
Note: As this group measures the accesses from all cores it only makes sense
to measure with one core per socket, similar as with the Intel Nehalem Uncore events.
