Hi Vanchinathan, It should be safe, but will probably have performance implications (and it’s technically not part of the standard).
I would think you’re likely to want L2’s per core, or up to possibly 4 core or so, and then a crossbar for interleaving across L3s. If you build these more sensible topologies you should not have problems. The system you describe is rather unrealistic… Andreas From: gem5-users <[email protected]<mailto:[email protected]>> on behalf of Vanchinathan Venkataramani <[email protected]<mailto:[email protected]>> Reply-To: gem5 users mailing list <[email protected]<mailto:[email protected]>> Date: Wednesday, 27 July 2016 at 06:09 To: gem5 users mailing list <[email protected]<mailto:[email protected]>> Subject: [gem5-users] Safety of SnoopMask Extension Hello all I am trying to run 64 cores, ARMV8, FS with Classic Memory on gem5. I found that the current SnoopMask can only support 64 connections and hence cannot be used to model more than 32 cores or more with separate L1 I- and D-Cache. This forced me to change the data type from uint64_t to uint128_t and modify some ostream related functions. This change works fine for the tested benchmark, However, I would like to know if this safe. Thanks a lot in advance!.
