Procesamiento Distribuido en una Red de Microprocesadores: Un Sistema de Comunicaciones

Abstract

A software system to communicate microprocessors, in order to use them as nodes of a virtual parallel machine, have been developed. A network of personal computers is
required. The present development was carried out under DOS as operating system, but its scope is more general. The system consists in a package of FORTRAN routines which may be called from any application program. A message-passing programming model is suitable for this architecture, i.e. each node run its own code with its own data. These data may belong to a part of the problem, as in the case of a subdomain decomposition, for instance. The general algorithm should take care of the necessary communications. The communication system is presented, as well as an example of its use.
