Extract from the NetSolve/GridSolve Description Document The emergence of Grid computing as the prototype of a next generation cyberinfrastructure for science has excited high expectations for its potential as an accelerator of discovery, but it has also raised questions about whether and how the broad population of research professionals, who must be the foundation of such productivity, can be motivated to adopt this new and more complex way of working. The rise of the new era of scientific modeling and simulation has, after all, been precipitous, and many science and engineering professionals have only recently become comfortable with the relatively simple world of the uniprocessor workstations and desktop scientific computing tools. In that world, software packages such as Matlab and Mathematica represent general-purpose scientific computing environments (SCEs) that enable users — totaling more than a million worldwide — to solve a wide variety of problems through flexible user interfaces that can model in a natural way the mathematical aspects of many different problem domains. Moreover, the ongoing, exponential increase in the computing resources supplied by the typical workstation makes these SCEs more and more powerful, and thereby tends to reduce the need for the kind of resource sharing that represents a major strength of Grid computing . Certainly there are various forces now urging collaboration across disciplines and distances, and the burgeoning Grid community, which aims to facilitate such collaboration, has made significant progress in mitigating the well-known complexities of building, operating, and using distributed computing environments. But it is unrealistic to expect the transition of research professionals to the Grid to be anything but halting and slow if it means abandoning the SCEs that they rightfully view as a major source of their productivity. We therefore believe that Grid computing’s prospects for success will tend to rise and fall according to its ability to interface smoothly with the general purpose SCEs that are likely to continue to dominate the toolbox of its targeted user base.

Public Clouds Private Cloud Elastic-R portal: single facade to public and private clouds
Elastic-R is a collaborative Virtual Research Environment. Users can share their machine instances, stateful remote engines, data,..
Reproducible research: A scientist can snapshot her computational environment and her data. She can archive the snapshot or share it with others.
