What is Resource-Aware Load Balancing

Chapter 2
Handbook of Research on Grid Technologies and Utility Computing: Concepts for Managing Large-Scale Applications
Assignment of tasks to a computational platform, taking into account its heterogeneous characteristics, with the objective of balancing the work assigned to processors. The tasks may be independent, or may have interdependencies described in a graph or digraph. In the latter case an additional objective is to minimize communication between processors. The assignment may be static, that is decided before tasks execute, or dynamic, that is tasks are assigned as conditions change.

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.
