Integration of Load Distribution into ParMod-C

The major part of environments for parallel programming in distributed systems either neglects load distribution support or realizes load distribution by the trivial task farming paradigm. This paper presents new language concepts for the support of application integrated load distribution. In addition to the task farming approach, the system can also dynamically migrate objects. Active objects and passive objects are combined to a very flexible and elegant programming model. Specific tasks for initialization and migration are used to realize efficient and portable load distribution mechanisms. The paper describes the new programming model and presents language constructs realizing this model. The language constructs are an extension of the parallel and distributed programming language ParMod-C. A program example shows the usage of the new language constructs and demonstrates easy implementation of load distribution using the new concept.     «
