Abstract:

A malleable parallel task is one whose execution time is a function of the number of (identical) processors allotted to it. We study the problem of scheduling a set of n independent malleable tasks on a fixed number of parallel processors, and propose an approximation scheme that for any fixed ε > 0, computes in 0(n) time a non-preemptive schedule of length at most (1 + ε) times the optimum.
