Handle Cache Coherence

[Applee]

Hi all,

      I have a problem about the cache coherence.  I check the code about  KNOB_ENABLE_CACHE_COHERENCE, then find that the value of this parameter doesn't have effect on the simulator.

      So I guess that in Macsim the L3 cache doesn't implement the cache coherence.  Do i have an exact understanding?

       Thanks for your time.

Best regards,

Applee

Currently macsim by itself doesn’t support cache coherence. 

You have to use sst-macsim for cache coherence support. 

Sorry for the confusion

Thank you for your help.

    Now I have another question. I only use the macsim.

    the number of cpu is 4

    the number of gpu is 6

    the number of l3  is 4

    the number of mc is 2

    For one cpu or gpu, such as cpu0 or gpu0, can it access all the l3 caches?

   

    Thanks for your time.

Best regards,

Applee
