DRAM read/write local to 4 [MegaEvents/s] 1.0E-06*UPMC0/time
DRAM read/write local to 5 [MegaEvents/s] 1.0E-06*UPMC1/time

Formulas:
DRAM read/write local to 4 [MegaEvents/s] = 1.0E-06*UNC_CPU_TO_DRAM_LOCAL_TO_0/time
DRAM read/write local to 5 [MegaEvents/s] = 1.0E-06*UNC_CPU_TO_DRAM_LOCAL_TO_1/time
DRAM read/write local to 6 [MegaEvents/s] = 1.0E-06*UNC_CPU_TO_DRAM_LOCAL_TO_2/time
DRAM read/write local to 7 [MegaEvents/s] = 1.0E-06*UNC_CPU_TO_DRAM_LOCAL_TO_3/time

Profiling group to measure the traffic from local CPU to the different
DRAM NUMA nodes. This group allows to detect NUMA problems in a threaded
code. You must first determine on which memory domains your code is running.
A code should only have significant traffic to its own memory domain.
