Subject: Re: [gem5-users] error about Ruby with Mesh topology
The mesh topology, as in the file Mesh.py, assumes that the number of
directory controllers is same as the number of number of cpus. Since the
number of directory controllers has not been specified on the command
line, it defaults to 1. If you mention number of directory controllers as
8, that should remove this error.
