     If you want to model a shared L2 cache like our CMP protocols you
have to use different cache mapping functions and different virtual
network connections.  It might be easier to try to split up the file into 2
different files, one controlling the L1 and one controlling the L2 (like
for our CMP protocols).

    Otherwise if you want to model private L1 and L2 caches I believe you
just use the standard-CMP file instead of standard-SMP file in the .slicc
file for the protocol to get rid of the assertion error.

     Alot of our profiling functions take in machineID numbers, so make
sure the right number is passed in for the right processor.  You can also
look at the generated SLICC code to help see this.
