DPVM: PVM for Dawning cluster systems

By means of some design algorithms and experimental results, this paper depicts the design, implementation and performance of DPVM (Dawning PVM), which is a port of the PVM (Parallel Virtual Machine) to the Dawning cluster systems. DPVM is derived from the original PVM 3.3.11 source code to retain compatibility with existing PVM applications. However, it uses a low-level direct communication protocol and the resource management software of the Dawning2000 cluster system. Experimental results show that DPVM is a well-implemented PVM implementation on an IBM RS6000 workstation cluster, and that it efficiently utilizes the Dawning cluster system with the efficient support of a low-level communication protocol and resource management service.
