I really think that's a recipe for disaster. Even on a regular machine you
need to treat tuning as an on-going feedback process. There's no such thing as
a fail-proof configuration since every application is different.
On an exotic machine like this you're going to run into unique problems that
nobody here can anticipate with certainty.
