Hi ,
I meet a porblem when using PCM V2.11. The QPI frequency is 9.6Gb/s. Why the QPI traffic is larger than 19.2, and the ration is so small?
BRs,
=================================================================================
Intel(r) QPI traffic estimation in bytes (data and non-data traffic outgoing from CPU/socket through QPI links):
QPI0 QPI1 QPI2 | QPI0 QPI1 QPI2
---------------------------------------------------------------------------------------------------------------
SKT 0 26 G 32 G 28 G | 27% 34% 29%
SKT 1 34 G 30 G 26 G | 36% 31% 27%
SKT 2 33 G 34 G 32 G | 35% 36% 34%
SKT 3 30 G 38 G 29 G | 32% 39% 30%

Hi,
PCM reports absolute values for the measured time interval. It does not normalize them (per second).
Best regards,

Hi Roman:
Is the utilization of QPI based on the QPI frequency? Take "QPI0 27%" as example. Does it mean the average thoughtput of QPI0 is 27% compared with 19.2GB/S ?
BRs,
LiYing
