Formulas:
Hyper Transport link4 bandwidth [MBytes/s]  = 1.0E-06*CPU_TO_DRAM_LOCAL_TO_0*4.0/time
Hyper Transport link5 bandwidth [MBytes/s]  = 1.0E-06*CPU_TO_DRAM_LOCAL_TO_1*4.0/time
Hyper Transport link6 bandwidth [MBytes/s]  = 1.0E-06*CPU_TO_DRAM_LOCAL_TO_2*4.0/time
Hyper Transport link7 bandwidth [MBytes/s]  = 1.0E-06*CPU_TO_DRAM_LOCAL_TO_3*4.0/time
-
Profiling group to measure the bandwidth over the Hypertransport links. Can be used
to detect NUMA problems. Usually there should be only limited traffic over the QPI
links for optimal performance.
