Re: [Gems-users] DNUCA problem

[Xuehai Qian <xuehaiq@xxxxxxxxx>]

I am looking at the NUCA protocol in GEMS 1.4.

 

It is a little bit hard to understand, I noticed there is notion of "token" in the protocol, is it based on taken coherence, or it is just the choose of the name of variable?

 

Can anyone tell me which paper or protocol is the NUCA protocol in GEMS based on?

 

It seems to be more complex than the original DNUCA paper.

I do not know how difficult it will be to port a GEMS 1.4 protocol to 2.0.

As far as using GEMS 1.4 with Simics 3.0, it should be
straightforward. Look in the GEMS 2.0 tarball at everywhere that is
sensitive to the settings in Makefile.simics_version. You will have to
grep through Makefiles and code, but the changes are all guarded by
#ifdefs in some form or another.
