Re: [Gems-users] regarding cmp configuration

[Bradford Beckmann <beckmann@xxxxxxxxxxx>]

...just a quick addendum

Any of the automatically generated non-ordered networks should work with
the CMP directory protocols.  Both PT_TO_PT and TORUS_2D topologies will
create the associated inter-chip network with the intra-chip network
being a single switch connecting all on chip components.
