well, IC.
the performance is rather poor than GTX590..... 32ns/day vs 4 ns/day
probably that's also something related to the warnings?

We have just committed the new CPU detection code in this branch,

means that currently only the NxN kernels are accelerated!
In the mean time, you might want to avoid production runs in 4.6.
I can't address the first warning, but the second is fairly obvious.
You're not using an official release, you're using the development
version - let the user beware. The code is not yet production-ready.
