Formulas:
L3 load bandwidth [MBytes/s] = 1.0E-06*L2_RQSTS_MISS*64.0/time
L3 load data volume [GBytes] = 1.0E-09*L2_RQSTS_MISS*64.0
L3 evict bandwidth [MBytes/s] = 1.0E-06*L2_LINES_OUT_DIRTY_ANY*64.0/time
L3 evict data volume [GBytes] = 1.0E-09*L2_LINES_OUT_DIRTY_ANY*64.0
L3 bandwidth [MBytes/s] = 1.0E-06*(L2_RQSTS_MISS+L2_LINES_OUT_DIRTY_ANY)*64/time
L3 data volume [GBytes] = 1.0E-09*(L2_RQSTS_MISS+L2_LINES_OUT_DIRTY_ANY)*64

Profiling group to measure L3 cache bandwidth. The bandwidth is computed by the
number of cache line allocated in the L2 and the number of modified cache lines
evicted from the L2. The group also reports total data volume between L3 and
the measured L2 cache. Note that this bandwidth also includes data transfers
due to a write allocate load on a store miss in L2.
