A thinking note for Parallel Program's Scalability.

	Strong Scalability
	---------------------
	Efficiency = c. (always)
	c : constant.

	* n, p can't affect efficiency in strong scalability.


	Weak Scalablility
	------------------------

CUDA

	CUDA ILP -> by compiler? or by hardware?
	CUDA -> in-order? or out-of-order?

	Occupancy = # of active warps / # of max resident warps
	Occupancy is determined from block size, register usage per a thread, shared memory usage per a thread.
	shared memory usage per a thread = shared memory usage in a block / block size.

	# of blocks >= # of SMs is good.
