[parsec-users] Mispredictiona and IPC relation

Recently in my simulations (4-core cmp) I found that for some
1- as the mispredictions are increased (which is
bad), IPC is
increased too (which is good) !
2- as the mispredictions
are decreased (which is good), IPC is
decreased too (which is bad) !
have to say, it is not a general observation. I mean only one
(bodytrack) fits '1' and one benchmark (streamcluster) fits
you think it is normal? till now I could find a reason for them.
for any suggestion
