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.
