What role does SUSY play in gauge/gravity duality?

Question

This question arises in my project of finding the conformal field theory dual to the bosonic part of the Yang-Mills theory, i.e. non-supersymmetric large $N$ YM theory. Supersymmetry is a constant setup in most of AdS/CFT solutions, but I wonder if SUSY is absolutely necessary for the duality? By focusing on the bosonic spectrum in the correspondence and neglecting the fermions, can gauge/gravity duality be established without SUSY? (I'm not against SUSY, but calculations will be much easier without it.)

Hmm, your project is to find the gravity dual of pure YM? And after that, you collect the million dollar prize?

"calculations will be much easier without it" .. What sort of calculations? Sometimes susy is all that makes a calculation possible.
