|
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. This group also output data volume transferred between the
|
|
L3 and measured cores L2 caches. Note that this bandwidth also includes data
|
|
transfers due to a write allocate load on a store miss in L2.
