[Gems-users] L1 cache miss absent again

[mehmetderin.harmanci@xxxxxxx]

 Hello,

   I'm running a simulation with MSI_MOSI_CMP_directory protocol, for a
  configuration of 4 processors. Since I'm using a CMP protocol I've set
  the REMOVE_SINGLE_CYCLE_DCACHE_FAST_PATH  parameter to true and I do
  not have any L1 cache misses, all the misses appear in L2 cache.
  I know I asked a similar question before but there I was using the
  MOSI_SMP_bcast and setting the above parameter to true. I do not see
  why I do not get any L1 cache misses here. Below I give my list of
  parameters and the content of my network file.  Any help will be very
  much appretiated.

    Thanks,

       Derin Harmanci
