A PVM Extension to Exploit Cluster Grids

摘要

Workstations belonging to networked clusters cannot often be exploited since they are not provided with valid IP addresses and are hidden from the Internet by IP addressable front-end machines. The paper presents a PVM extension that enables such clustered machines hidden from the Internet to take part in a PVM computation as hosts. This way, programmers can exploit low-cost, networked computing resources widely available within departmental organizations in a well-known programming environment, such as PVM, without having to adapt their large-scale applications to new grid programming environments.
