Scientific computing often requires the availability of a massive number of computers for performing large scale experiments. Traditionally, these needs have been addressed by using high-performance computing solutions and installed facilities such as clusters and super computers, which are difficult to setup, maintain, and operate. Cloud computing provides scientists with a completely new model of...
The Gridbus workflow management system (GWMS) is designed to execute scientific applications, expressed in the form of workflows, onto Grid and Cloud resources. With the help of this system, we demonstrate a computational and data-intensive Image Registration (IR) workflow for functional Magnetic Resonance Imaging (fMRI) applications on Clouds and global Grids. We also present a demonstration of the...
The convergence of telecom and Internet are yet to be matured enough to effectively solve the major challenges, like quality of service, different kinds of charging, and security. IP multimedia subsystems (IMS) techniques are one of the strong contenders to solve the above problems by proposing overlay network architecture. It is imperative to find out an optimum network design to support rapidly...
