Hi all, Just to be clear: If you care about _modifying_ and _exploring_ coherency protocols Ruby is the best option. For crossbar-based systems with multi-level MOESI, I’d say the classic memory system does a pretty darn good job. Moreover, the classic memory system is much faster, and far more configurable with respect to topologies.

I'm not familiar with the details of the T1's coherence protocol. If you really care about modeling the coherence protocol, then you should be using the Ruby memory model. You can look through all of the protocols for Ruby (in src/mem/protocol) and pick which one is most similar.

Although I did put the option for “MinorCPU” in the build_opts folder, in the ~/build/SPARC/minor folder there is no compiled files other than just a “SConscript” file. As oppose to, in the “o3” folder, there are a bunch of linked files for the CPU. So this means the “Minor” cpu is not getting compiled as you suspected. What should be the way to go for this? Should I simply delete everything again and recompile GEM5 completely from scratch or simply deleting the ~/build/SPARC/* and then rebuilding may do the trick? Is there any other way you think may be possible? I shall look into the SE script for multiple workload running on the CPU. Also are you familiar with the L1 Directory/L2 Directory, as that is how the SPARC maintains the coherency. What options in GEM5 would give me these numbers? Thanks again for your time. ☺ Monir _______________________________________________ gem5-users mailing list [email protected]<mailto:[email protected]> http://m5sim.org/cgi-bin/mailman/listinfo/gem5-users IMPORTANT NOTICE: The contents of this email and any attachments are confidential and may also be privileged.
