I am trying to figure out the amount of memory bus traffic in
From http://assets.devx.com/goparallel/18027.pdf I thought that
BUS_TRAN_BURST.SELF (multiplied by 64) would bea good measure.
I also expected that this number would be within
2x of MEM_LOAD_RETIRED.L2_LINE_MISS (there are no RFOs
etc.). However, I see that BUS_TRAN_BURST.SELF is ~4 to 5 ofx
MEM_LOAD_RETIRED.L2_LINE_MISS. I have been trying to figure
out where thedifference comes from but I have not found a reasonable
I also measuredL2_LD.SELF.DEMAND.MESI andL2_LD.SELF.ANY.MESI
and found that L2_LD.SELF.DEMAND.MESI is about half of
L2_LD.SELF.ANY.MESI and that L2_LD.SELF.DEMAND.MESI is about
double of BUS_TRAN_BURST.SELF.
The number of L2_M_LINES_OUT.SELF.ANY events is about 1.5 of
the number of MEM_LOAD_RETIRED.L2_LINE_MISS events.
Any help would be greatly appreciated.
