I always leave hardware to others! 

Fluent should pick up the HPC/parallel licence automatically, so assuming it's all set up properly you just put in the core count & it'll launch. If it doesn't please check the errors on here: nearly all install problems have been asked before. 

The gpu acceleration should work on RSM but the benefit may be marginal. It's more noticeable on the some of the radiation equations. The new gpu solver will give a significant speed up, but you need the right sort of gpu.
