METRICS
Runtime (RDTSC) [s] time
Link bandwidth L0 [MBytes/s] 1.0E-06*UPMC0*4.0/time
Link bandwidth L1 [MBytes/s] 1.0E-06*UPMC1*4.0/time
Link bandwidth L2 [MBytes/s] 1.0E-06*UPMC2*4.0/time
Link bandwidth L3 [MBytes/s] 1.0E-06*UPMC3*4.0/time
LONG
Formulas:
Link bandwidth L0 [MBytes/s] = 1.0E-06*UNC_LINK_TRANSMIT_BW_L0_USE*4.0/time
Link bandwidth L1 [MBytes/s] = 1.0E-06*UNC_LINK_TRANSMIT_BW_L1_USE*4.0/time
Link bandwidth L2 [MBytes/s] = 1.0E-06*UNC_LINK_TRANSMIT_BW_L2_USE*4.0/time
Link bandwidth L3 [MBytes/s] = 1.0E-06*UNC_LINK_TRANSMIT_BW_L3_USE*4.0/time

Profiling group to measure the HyperTransport link bandwidth for the four links
of a local node. This indicates the# data flow between different ccNUMA nodes.
