The importance of parallel programming is increasing year after year since the power wall popularized multi-core processors, and with them, shared memory parallel programming models. In particular, task-based programming models, like the standard OpenMP 4.0, have become more and more important. They allow describing a set of data dependences per task that the runtime uses to order the execution...

This paper presents a user-interactive decision support system (DSS) for the management of the Lake Kariba reservoir. Built in the fourth-generation computer language IFPS, the system takes into account relevant reservoir characteristics and parameters, such as the amount of hydropower generated, reservoir storage throughout the year, and the amount of water released for down-stream usage. The ...

the state agricultural extension system (saes) due to serious limitations of finance, equipment and staff could not meet all the expectation of the farmers. use of unemployed young graduates' services as consultant, farm manager or farm supervisor has been considered as a solution to the problem and as an alternative, in recent years. this research was aimed at an evaluation of the extensi...

Dynamic configuration is a desirable property of a distributed system where dynamic modification and extension to the system and the applications are required. It allows the system configuration to be specified and changed while the system is executing. This paper describes a software platform that facilitates a novel approach to the dynamically configurable programming of parallel and distribu...

In last January’s Manager column, “Fear of Trying: The Plight of the Rookie Project Manager,” Roger Pressman asked a question critical to the future of our profession: “So, how do we grow a good project manager? What do we teach the rookie who has just been appointed to lead her first software project?” Instead of answering this question directly, Pressman focused his article on four key skills...

The extension of object-oriented middleware to component-oriented middleware is now commonplace, with many distributed applications structured as remote clients invoking services constructed from components. An advantage components offer over objects is that only the business logic of an application needs to be addressed by a programmer. An application server hosts components, managing supporti...

This paper presents an extension to the Mobility Object Manager (MOM) for the RWI robots, which is currently being developed at the University of Essex. It presents a new user friendly interface extension to MOM for monitoring and interacting with the robot during the development of control algorithms. A new viewer has been incorporated to enable concurrent state reflection of both sensor and a...

Various proposals have been made for declustering two-dimensionally tiled data on multiple I/O devices. Recently it has been shown that strictly optimal solutions only exist under very restrictive conditions on the tiling of the two-dimensional space or for very few I/O devices. In this paper we explore allocation methods where no strictly optimal solution exists. We propose a general class of ...
