Detailed Description

Version of refinement: for multi-gpu simulations, without communication hiding ("streams"), only exchange the interpolated cells.

recommended for multi-gpu simulations if the chosen collision kernel does NOT support the use of cuda streams

operator()()

void vf::gpu::RefinementAndExchange_noStreams_exchangeInterface::operator()	(	UpdateGrid27 *	updateGrid,
		Parameter *	para,
		int	level
	)

steps:

1. interpolation fine to coarse

1. exchange information between GPUs (only nodes which are part of the interpolation)

1. interpolation coarse to fine
