Runtime (RDTSC) [s] time
CPI PMC5/PMC4

Formulas:
CPI = PM_RUN_CYC/PM_RUN_INST_CMPL
L2 load bandwidth [MBytes/s] = 1.0E-06*(PM_L2_LD+PM_L2_INST)*128.0/time
L2 load data volume [GBytes] = 1.0E-09*(PM_L2_LD+PM_L2_INST)*128.0

Profiling group to measure L2 load cache bandwidth. The bandwidth is computed by the
number of cacheline loaded from L2 cache to L1.
