Both improving the execution efficiency and reducing the execution cost are essential for scientific workflows in cloud environments. As many scientific workflow tasks become more data-intensive and computation-intensive, storing their outputs in cloud for reuse is a feasible way to achieve such objectives. Because data storage in cloud would increase the storage cost, though it might mean less computation time due to data reuse, it is important to determine the proportion of the output data… CONTINUE READING
