Subject: | [Gems-users] MOESI_SMP_directory number of directories |
Hi, I was wondering if it is possible to use MOESI_SMP_directory protocol with fewer directory controllers than the number of chips. The reason is that I am using the multi-chip configuration to model large CMPs (>> 16 processors) and don't want to model the same number of memory/directory controllers as processors. I assume that I will have to re-define the mapping of addresses to directory controllers - is that correct ? Anything else ? By the way, I am using MOESI_SMP_directory because I need a private L2 cache which other protocols do not have. Thanks... Stamatis |
