Abstract
{qlzheng, glchen, lshuang} @ ustc. edu. cn Record and Replay technique has been proved an effective solution to cyclic debugging of nondeterministic parallel program. Because of nondeterminism, a parallel program given the same inputs on successive runs can sometimes produces different results. In this paper; an optimal record and replay technique is presented, which produces less overhead in time and space by using the non-overtaking rule provided by MPI and PVM. 1.
