| NANYANG CAMPUS GRID Accounting System | | The "Grid" concept is motivated by the need for coordinating resource sharing and problem solving in dynamic environments. Collaboration lies at the heart of Grid computing. This collaboration and sharing is, necessarily, highly controlled, with resource providers and consumers' levels of authority and accessibility clearly defined. | | | | | | DESIGN OF A GRID-ENABLED LOW-COST SUPERCOMPUTER WITH MASSIVELY PARALLEL ACCELERATORS | | Hybrid computing describes the combination of fine-grained and coarse-grained parallelism within an architecture, e.g. within the processors of a loosely coupled computational grid, tightly coupled massively parallel processor arrays are embedded in order to accelerate compute-intensive tasks. The driving force and motivation behind hybrid computing is the price/performance ratio. Using a computational grid consisting of several geographically distributed Beowulf PC-clusters is currently one of the most efficient and simple ways to gain supercomputer power for a reasonable price. | | | MCCF: A Distributed Grid Job Workflow Execution Framework | | With the explosion of scientific data, distributed scientific applications present great challenges to the existing job workflow execution models over the Grid. Based on the idea of having executable codes as part of Grid resources, a Mobile Code Collaboration Framework (MCCF) utilizing light-weight mobile agents and dynamic services for distributed job workflow execution is investigated in this project. The Light-weight Mobile Agent (LMA) technique is used to adapt job workflow execution to the dynamic characteristics of the Grid and to reduce the security risks. | |
