Hi Mahmood, Assume the number of cores are 4. So, does "Nodes-fag-branches" represent the total number of branches on 4 cores?
Yes. "Nodes-fag-branches" shows the total number of branches on all cores (i.e. the whole chip). This is true for all "Nodes-X" stats. Another question is why "sys-cycles" from UP.OoO doesn't change to "Nodes-cycles" in CMP.L2SharedNUCA.OoO? Statistics of components that have one instance in the system are prefixed by "sys-" (this is a naming convention used in Flexus’s statistics package). For example, on-chip network’s statistics in CMP simulators have the “sys-” prefix in their names. “sys-cycles” shows the number of simulation cycles which is a system-wide stat and is independent of the number of cores. Therefore the same naming convention is used in its name.
