The performance of adaptive protocols using either aggressiveness control, risk control or both are compared to each other and an optimistic protocol. Empirical results are presented from execution on a CM-5 using up to 256 nodes. The results demonstrate that between the aggressiveness and risk control protocols, the aggressiveness control protocol performs better overall; however, risk control performs best in some situations. A protocol combining aggressiveness and risk control is more consistent at performing better than an optimistic protocol. Also, the use of straggler information is seen to enhance the risk control protocol.
