A3: Scheduling and Load Balancing

Principal Investigators:

Prof. P. Sanders

Scientific Researchers:

Dr. D. Luxen, J. Speck

Abstract

A key innovation of invasive computing is added flexibility. Subproject A3 investigates algorithms that use this flexibility to actually improve performance. In particular, these load balancing algorithms have to decide how much parallelism to use, where to assign parallel jobs, and how to dynamically change these decisions. In these decisions, processor resources, communication costs, and competing requirements of the jobs have to be taken into account and the load balancing algorithms themselves have to scale to large, possibly heterogeneous systems with stringent latency requirements.
Project A3 terminated after the first funding phase.
