Re: [Gems-users] What's the meaning of "MR" state?

[Mike Marty <mikem@xxxxxxxxxxx>]

I don't believe this state is ever used unless a replication policy is 
implemented. The idea is to implement some policy that will selectively 
allocate L1 replacements into the local L2 bank rather than the 
statically selected Home L2 bank.
