J. Happe, H. Groenda, R.H. Reussner
2009 2009 IEEE International Symposium on Modeling, Analysis & Simulation of Computer and Telecommunication Systems  
In particular, we are interested in the influence of multiprocessor load balancing on software performance.  ...  For example, an optimal scheduling policy for multi-server systems, such as shortest remaining processing time (SRPT) for single-server systems, is not yet known in queueing theory.  ...  One of the major influences for software performance in SMP systems is the multiprocessor load-balancing policy implemented in general purpose operating system (GPOS) schedulers.  ...

Dynamic load balancing for distributed memory multiprocessors

George Cybenko
1989 Journal of Parallel and Distributed Computing  
In this paper we study diffusion schemes for dynamic load balancing on message passing multiprocessor networks.  ...  Using a realistic model of interprocessor communications, we show that a diffusion approach to load balancing on a hypercube multiprocessor is inferior to another approach which we call the dimension exchange  ...  The goal of load balancing is for each processor to perform an equitable share of the total work load.  ...
