Re: [Gems-users] Accurate timing and performance simulation of x86 machines

[Mike Marty <mikem@xxxxxxxxxxx>]

GEMS is best suited towards modeling a shared-memory hierarchy.  It does
not handle I/O devices like Myrinet and Infiniband.

If you are not committed to Simics, I believe the Michigan M5 simulator
might be better suited to simulating a cluster with custom networks.
