This paper address the problem of static task clustering and scheduling of a parallel program given as a Directed Acyclic Graph(DAG) with duplication. Scheduling of task graphs onto multiprocessors is known to be an NP-complete in most cases leading to solutions based on heuristics. In this paper, a novel task-duplication scheduling heuristic is presented. Our approach differs from other heuristics...
Distributed Object Oriented (DOO) applications have been developed for solving complex problems in various scientific fields. One of the most important aspects of the DOO systems is the efficient distribution of software classes among different nodes in order to solve the mismatch problem that may appear when the software structure does not match up the available hardware organization. We have proposed...
There have been a large number of projects based on the Distributed Object Oriented (DOO) approach for solving complex problems in various scientific fields. The Mismatch problem is one of the most important problems facing the DOO system, where the initial design of the DOO application does not give the best class distribution. In such a case, the DOO software may need to be restructured. In this...
Over the last few years, designers and engineers utilized the Object-Oriented (OO) approach in developing distributed software systems. One of the most important aspects of the Distributed Object Oriented (DOO) systems is the efficient distribution of software classes among different nodes. The initial design of the DOO application does not necessarily have the best class distribution and may need...
