I'm running PCM tool on the machine with Intel(R) Xeon(R) CPU X5690 @ 3.47GHz "Intel(r) microarchitecture codename Westmere-EP". The output of the PCM tool has the following information on QPI. Can you please share details on the below in the output, what does it actually mean ?
Total QPI incoming data traffic: 65 M QPI data traffic/Memory controller traffic: 0.84
And also please let us know how data cache misses affect QPI output value.
