New scheduling problems coming from GRID computing

International audienceIn this article, we expose how the availability of an increasing computational power affects scheduling problems that uses grid computing to utilize this power. We first present how scheduling problems are currently handled, and the so-called "next-generation" clusters that will have different needs. Starting from those, we discuss "real-life" issues that will affect the scheduling and its resolutions and we expose how it affects scheduling and assignment problems. Then, we conclude with discussing some emerging methods to increase scheduling performances
