文摘In this paper,we present an approximate formula for calculating th speedup of a concurrent non-DO loop.The execution pattern of a concurrent non-Do loop is analyzed.As a result,the optimal concurrent step for a non-DO loop is presened and proved.With the analysis of the speedup of a concurrent non-DO loop,a simple and useful approximate formula is deduced,which is just the mathematical limit of speedup when the number of iterations is approaching infinity.
