Resource performance management on computational grid

The ability to have applications draw computing power from a global resource pool to achieve high performance has become a new challenge for distributed computing and Internet technologies. This challenge not only involves solving technical difficulties in the construction of Grid environments, it also involves resource sharing and performance concerns. This paper presents a resource performance manager that fits in the current Globus implementation of computational Grids, and shows how it can aid in the Grid's expansion, illustrated by some experiments carried out on the UCM-CAB testbed.
