Massive Parallelism with Workstation Clusters {

Workstation cluster computing recently has become an important and successful technique. The communication bottleneck limits this approach to small and medium sized conngurations of up to 30 workstations for most applications. This paper demonstrates that for certain algorithms massively parallel cluster computing using thousands of workstations in the Internet is feasible. It describes structures for the coordination of a large number of geographically dispersed processes. The paper introduces Lola, a library supporting massively parallel computing in wide area networks, and provides an application example.
