1. What causes the introduction of caches in parallel architectures?

	Caches can decrease the performance gap between the cors and the memory.
	Caches can be used to accelerate the computation in the cores for parallel programs
	Since higher clock frequencies would cause to much heat on the chip, caches are the only way to accelerate the core.
