Any major research institution has a substantial number of computer systems on its campus, often in the scale of tens of thousands. Given that a large amount of scientific computing is appropriate for execution in an opportunistic environment, a campus grid is an inexpensive way to build a...

The "Grid", an initiative of the distributed computing community, offers unprecedented levels of computing power for organisations to apply to solving their business problems. Uniquely it also offers the communications infrastructure required to overcome the "tyranny of distance" observed by...

This paper reports a UK Economic and Social Research Council project that is exploring the use of Grid technologies to manage distributed data and act as a secure infrastructure for the delivery of computing power to distributed teams. The application focus used to test this infrastructure is...

The INWA Grid project connects grid resources in EPCC (Edinburgh, Scotland), Curtin Business School (Perth, Western Australia) and the Chinese Academy of Sciences (Beijing, China). The project has demonstrated the application of grid computing power to the analysis of distributed data drawn from...

We investigate the gains obtained by using GRID, an innovative web-based technology for parallel computing, in a Risk Management application. We show, by estimating a parametric Value at Risk, how GRID computing offers an opportunity to enhance the solution of computationally demanding problems...

The cloud computing paradigm has been defined from several points of view, the main two directions being either as an evolution of the grid and distributed computing paradigm, or, on the contrary, as a disruptive revolution in the classical paradigms of operating systems, network layers and web...

We implement a dynamic programming algorithm on a computational grid consisting of loosely coupled processors, possibly including clusters and individual workstations. The grid changes dynamically during the computation, as processors enter and leave the pool of workstations. The algorithm is...

This paper develops a sociomaterial perspective on digital coordination. It extends Pickering’s mangle of practice by using a trichordal approach to temporal emergence. We provide new understanding as to how the nonhuman and human agencies involved in coordination are embedded in the past,...

We study the following grid scheduling problem. A set of independent tasks, submitted to a grid external scheduler (ES), has to be assigned to a set of grid computing sites, each one controlled by a local scheduler (LS), for their execution. With each task are associated a release date and a...

The problem description of data models and types of databases has generated and gives rise to extensive controversy generated by their complexity, the many factors involved in the actual process of implementation. Grids encourage and promote the publication, sharing and integration of scientific...
