An adaptive scheduling method for grid computing

Abstract

This paper presents an adaptive scheduling method, which can be used for parallel applications whose total workload is unknown a priori. This method can deal with the unpredictable execution conditions commonly encountered on grids. To address this scheduling problem, parameters which quantify the dynamic nature of the execution conditions had to be denned. The proposed scheduling method is based on an online algorithm so as to be adaptable to the varying execution conditions, but avoids the idle periods inherent to this on-line algorithm. © Springer-Verlag Berlin Heidelberg 2006.
