Abstract

Distributed systems (e.g. a LAN of computers) can be used for concurrent processing for some applications. However, a serious difficulty in concurrent programming of a distributed system is how to deal with scheduling and load balancing of such a system which may consist of heterogeneous computers. Distributed scheduling schemes suitable for parallel loops with independent iterations on heterogeneous computer clusters have been proposed and analyzed in the past. Here, we implement the previous schemes in the CORBA (Orbix). We also present an extension of these schemes implemented in a hierarchical master-slave architecture. We present experimental results and comparisons.
