SuperPi on GPU, were going CUDA

[Lestat]

will we still be able to do single core only runs on a multi core cpu?

its not the cpu here its the GPU. gpu's are always multi threaded never single threaded (correct charles?)

and why would you want to do a single core run ?
if its for stability testing you can use orthos (SP2004) and set the affinity to the core you want.
