THE  EASYGRID  PROJECT



DESCRIPTION

In the near future, the Computational Grid will become an important and powerful computing platform in both the scientific and commercial distributed computing communities for the execution of large-scale, resource-intensive applications. The goal of the grid is to aggregate collections of shared, heterogeneous, and distributed resources to provide computational ``power'' to a parallel application. Nevertheless, it remains a challenge for applications (and users) to exploit the performance potential of these resources. Designing efficient applications for traditional parallel machine is not easy, for computational grids, the task is even more challenging. This project proposes the EasyGrid methodology and framework for the efficient and robust execution of MPI programs across clusters of distributed computing clusters. The principal objective of this work is to identify the application-oriented middleware necessary for, as well as develop a framework to automatically generate, system-aware (grid-enabled) applications capable of executing in the dynamic, unstable, and distributed environment offered by computational grids.

  Description
Post-Graduate Opportunities

Admissions to MSc and DSc (equivalent to Ph.D) post-graduate courses here at IC-UFF are open until the 16th of January, 2004. (Note that DSc candidates are required to present, together with their prospective supervisor, a research project proposal.) If you are considering postgraduates studies and are interested in working the area of Grid Computing, let me (Prof. Vinod) know.
Employment Opportunities

We also have a job vacancy for a someone to manage the GridRio Computational Grid. If you have experience with Linux, Globus ToolKit and Web development (e.g. HTML, PHP), or atleast interested in learning as you go along, please enter in contact with Prof. Vinod.
