Abstract

We are interested in the parallel complexity of computing a minimum length schedule for executing n tasks of equal length on m identical processors constrained by a tree precedence relation. While this problem can be solved in linear time sequentially, the best known parallel algorithms require O(log n) time using n2 processors or O(log2 n) time on n processors. In this paper we present two new parallel algorithms. The first runs in time O(m log n) using n/log n processors of an EREW PRAM and hence is work and time optimal for any constant m. The other runs in time O(log n log m) using n/log m EREW PRAM processors.
