Optimizing and Load Balancing Metacomputing Applications

While the theoretical possibilities of metacomputing, in the sense of “heterogeneous supercomputing using WANs”, are obvious, it is difficult to utilize this potential in practice. In this paper, a programming model and communication library are presented which enable an efficient distribution of applications on a metacomputer. This is achieved by communication optimizations and a good load balance even for linked computers with considerably different computational speeds. First practical results show the benefits of the optimizations.
