This video introduces GPU computing and the SAXPY.

1. For which kind of program can we expect improvements with GPUs?

2. What does GPU stands for?

3. Why do we expect an overhead in the GPU timings?

	The data must be copied to an extra device first and has to be transferred back later
	A GPU core is "weaker" than a CPU core
	For "small" problems like the SAXPY, the whole power of a GPU is rarely used
	All of the above
