Abstract

Grids are dynamic systems in which an important factor is played by the scheduling policies. Moreover scheduling mathematical problems on grids is not a trivial task as it is difficult to estimate their runtimes. This issue is even harder if these problems are part of a workflow. This paper tries to solve this aspect by offering a unified view related to scheduling independent and dependent task batches and a solution in the form of a Scheduling Algorithm and Platform adapted for this particular scenario. Experimental results show that the envisioned heuristic is efficient with regard to other classic approaches.
