High Performance Computing 1
Little’s Law of High Performance Computing
•Assume:
•Single processor-memory system.
•Computation deals with data in local main memory.
•Pipeline between main memory and processor is fully utilized.  •Then by Little’s Law, the number of words in transit between CPU and memory (i.e. length of vector pipe, size of cache lines, etc.)
• =  memory latency  x  bandwidth.
