[Gems-users] Problems when running only a process on CMP

["张量" <congwu.zhang@xxxxxxxxx>]

    Hi,everyone!
    I'm using gems-2.0 and MESI_SCMP_bankdirectory coherence protocol. I want to check the conflicts in shared L2 cache.
First I run gzip on one of the 16 processors ( processor 5 ,in my configuration)  and let the other 15 processors run idle
function :
      while(1){
             asm volatile ("srl %g0, 0, %g0");
      }
   I believe that only L1 on P5 should send request to the shared L2,   but I find that all L1s keep sending requests (L1_GETS,L1_GETX . . ) to L2 frequently , that's very confusing! 
   Why?
