Subject: | [Gems-users] MOESI_CMP_directory |
Hello, I have a few questions regarding MOESI_CMP_directory protocol. -By looking at the source code (e.g. MOESI_CMP_directory-L1cache.sm), I see there is neither Exclusive nor Invalid state implemented. Why is that? -There is no transient state to the extra states M_W, MM, and MM_W. Are the extra states never used? -Is there a state transition diagram for the MOESI_CMP_directory protocol? It would really help to understand the protocol and the source code. -It is said that this protocol uses non-inclusive L1/L2 caching with blocking caches. Could somebody please elaborate? Thank you for your help.
