In this paper, a method for estimating task execution times is presented, in order to facilitate dynamic scheduling in a heterogeneous metacomputing environment. Execution time is treated as a random variable and is statistically estimated from past observations. This method predicts the execution time as a function of several parameters of the input data, and does not require any direct information about the algorithms used by the tasks or the architecture of the machines. Techniques based
