What is High Capacity Computational Grid

Chapter 2
Handbook of Research on Grid Technologies and Utility Computing: Concepts for Managing Large-Scale Applications
A grid platform dedicated to high performance computing (HPC) applications and generally consisting of an aggregation of multiple HPC clusters. These grids are space-shared, that is processors only execute a single user’s process(es) at a time. The clusters may be located in one organization, or they may be more spread out geographically, which can pose additional problems of high latencies.

Abstract
The problem of load balancing parallel applications is particularly challenging on computational grids, since the characteristics of both the application and the platform must be taken into account. This chapter reviews the wide range of solutions that have been proposed. It considers tightly coupled parallel applications that can be described by an undirected graph representing concurrent execution of tasks and communication of tasks, executing on computational grids with static and dynamic network and processor performance. While a rich set of solution techniques have been proposed, there has not been of yet any performance comparisons between them. Such comparisons will require parallel benchmarks and computational grid emulators and simulators.
