In this paper, we study and compare grid and global computing systems and outline the
benefits of having a hybrid system called DIRAC. To evaluate the DIRAC scheduling for high …

Processing of data in many data analysis applications can be represented as an acyclic,
coarse grain data flow, from data sources to the client. This paper is concerned with …

This paper addresses the problem of scheduling parallel program tasks onto computational
grid to minimize the execution time of the parallel program and the number of required …

Due to the high complexity of Grid computing systems, experimentation on a real Grid
system is challenging and time consuming. Moreover, deploying a Grid system demands a …

Contemporary land information systems allow the generation of models of numerical
surfaces by applying a number of interpolation algorithms. The appropriate selection of …

In 2006 the Route load balancing algorithm was proposed and compared to other
techniques aiming at optimizing the process allocation in grid environments. This algorithm …

In this paper we present a model and simulator for many clusters of heterogeneous PCs
belonging to a local network. These clusters are assumed to be connected to each other …

In this paper we investigate the effects of IP channels on speech recognition systems and
methods to recover the associated performance degradation. There are three major VoIP …

In this paper we present a model and simulator for many clusters of heterogeneous PCs
belonging to a local network. These clusters are assumed to be connected to each other …

Large-scale grids and other federations of distributed resources that aggregate and share
resources over wide-area networks present major new challenges because they couple the …
