Re: [Gems-users] MOESI_SMP_token Owner Token

["Mike Marty" <mikem@xxxxxxxxxxx>]

The Owner is accounted for in messages by setting the message type as
CoherenceResponseType:DATA_OWNER.  In cache tags, it is accounted for in the
SLICC state of the line.  In an actual hardware implementation, you would
have an extra bit with the token count.  

max_tokens() is defined in ruby/common/Global.h

You might try adding an assertion to setState() to ensure that the Owner
always has more than half the tokens.  This should be true for the
performance protocol implemented in MOESI_SMP_token
