In this paper, we present the defini-tion of maximum loop speedup, which is the metricof parallelism hidden in loop body. We also studythe classes of Do-loop and their dependence as wellas the parallelism they contain. How to exploit suchparallelism under heterogeneous computing environ-ment? The paper proposes several approaches, whichare eliminating serial bottleneck by means of heteroge-neous computing, heterogeneous Do-all-loop schedul-ing, heterogeneous Do-a-cross scheduling. We findthat, not only on theoretical analysis but also on ex-perimental results, these schemes acquire better per-formance than in homogeneous computing.
