Not that I'm aware of.

There are two options here from what I know:
1. Turn off the embedded SM temporarily and run OpenSM (in one of it's
various routing modes)
2. Get your topology into a simulator and run OpenSM on it

BTW, there are scripts which will work with any SM to dump the routing
tables (dump_lfts/mgfts.sh) if that is how you are doing the comparison.
