| Abstract |
Parallel Virtual Machine (PVM) is a software tool to allow concurrent computing on heterogeneous networked computers via Unix sockets using UPD datagrams. Applications programmers exploit multiprocessing by explicit high-level C or FORTRAN calls to interprocessor communication routines, as in a Portable Instrumented Communication Library (PICL) or the compilers of MIMD vendors. These capabilities allow unused cycles in a network to be utilized and parallel implementations of applications to be developed and tested. The paper reports an implementation of a PVM-FORTRAN code for two-phase flow in porous media using PVM on both homogeneous and heterogeneous processor networks. Each processor runs the same source code asynchronously using the single-program-multiple-data (SPMD) approach and synchronizes at convergence tests. |
