Formulas:
|

|
|
Memory read bandwidth [MBytes/s] = 1.0E-06*(L2_DATA_READ_MISS_MEM_FILL+HWP_L2MISS)*64.0/time
|
||
|
|
Memory read data volume [GBytes] = 1.0E-09*(L2_DATA_READ_MISS_MEM_FILL+HWP_L2MISS)*64.0

Bandwidth and data volume of read operations from the memory to L2 cache. The
|
||
|
|
metric is introduced in the book 'Intel Xeon Phi Coprocessor High-Performance
