This group measures the data traffic on the UPI (socket interconnect). The group
|
|
measures all filled data slots (9 slots per 64 Byte data transfer), that's why
|
|
the count needs to be divided by 9. These 9 data chunks are not transferred in
|
|
a single flit but there is one flit for the header and three flits for the data.
|
|
The metrics show higher values as expected because the events count also
|
|
different transfers which include data.
