Re: [Gems-users] MOESI_SMP_directory number of directories

[Greg Byrd <gbyrd@xxxxxxxx>]

How about just redefining the mapping of addresses to 
directories, and leaving everything else the same?  You'd 
still create one directory per processors, but the 
directories that don't get mapped will go unused.  That 
would be easier than trying to redo all the configuration stuff.
