You can create a protocol in Ruby that does not have coherent L2 caches,
however Ruby is only a timing simulator. The function of the system is
modeled by Simics which assumes your multiprocessor is cache-coherent. If
you can figure out a way to use Simics with a non-coherent target machine,
then you can use Ruby to add timing fidelity.
