“…The described parallel program execution control has been included into a graphical parallel program design system PS-GRADE system [12], which extends the original P-GRADE system [13] [14]. The crucial feature of the extended PS-GRADE system are synchronizers.…”

Many computational problems have irregular data/control characteristics, which make programs difficult to be efficiently implemented in parallel systems. Due to irregular character of code or data, even division of work between processors at application startup is frequently impossible. Runtime optimization is possible, but it requires a constant exchange of control information and/or data during runtime is required. A novel parallel application control method is proposed in the paper. It is based on application global state monitoring for runtime irregular application control. The method provides a ready-to-use control infrastructure, which can be conveniently applied by a programmer. Both suitability and efficiency of the proposed control method are discussed in the paper based on two selected numerical applications: adaptive integration and branch and bound search. The presented experimental results were obtained with PS-GRADE graphical parallel design system, which embeds the proposed control method. The results confirm the efficiency of control based on global predicates in irregular computations.

The paper concerns adaptation of the graphical parallel programming environment PS-GRADE based on advanced global synchronization and control mechanisms to Grid-level application control. We propose that program execution control by synchronizers known at the process level is extended and used to coordinate parallel applications executed on Grid. We introduce explicit inter-application, or Grid-level, synchronizers. The Grid-level synchronizers generate application execution control decisions based on predicates computed on global application states. They co-operate with application level synchronizers, which are able to send state reports and receive control signals over Grid communication network. In the proposed solution, the application workflow paradigm has been enriched to enable designing more flexible control between otherwise independent applications. We discuss types of Grid applications whose global control can be implemented by the use of synchronizers-based infrastructure. An application example illustrates the proposed control design strategy.

“…For a summary of algorithm animation and software visualization systems, see [18,6]. For instance, p-grade [17] is an environment to support the user development of parallel programs. Compared to these tools, Visidia is kept as simple as possible and has the advantage to be founded on a solid theoretical base.…”

Visidia is a tool for the simulation and the visualization of distributed algorithms. The simulation has been done using one mchine [2,3]. In this paper, we present an approach of such a simulation by using a network of machines. Indeed, we suppose that several machines connected by a network can take part in the simulation. We give both a specification of the set up model and a description of the implementation carried out.
