Title: An Introduction to Research Issues in Heterogeneous Parallel and Distributed Computing
Hosted by MERCS (Monash eResearch Centre) and Message Lab/DSSE (Monash eScience Grids Lab)
Date and Time: Wednesday 11 June 2008 at 2pm
Seminar Venue: Seminar Room H7.84, 7th Floor, Building H, Caulfield
Abstract: In heterogeneous parallel and distributed computing environments, a suite of different machines is interconnected to provide a variety of computational capabilities. These capabilities are used to execute a collection of tasks with diverse computational requirements. The execution times of a task may vary from one machine to the next, and tasks must share the computing and communication resources of the system. An important research problem for heterogeneous computing is how assign tasks to machines and schedule the order of their execution to maximize some given performance criterion. An overview of a conceptual model of what this involves will be given. An example of resource allocation research will be presented. The example involves an ad hoc grid environment, with energy constrained mobile computing devices that could be used in a disaster management scenario. Open problems in the field of heterogeneous parallel and distributed computing will be discussed. “Alligators” that make heterogeneous computing challenging will be shown.
