Abstract
Scientists in many fields are developing large-scale workflow applications consisting of hundreds of thousands of tasks and requiring thousands of hours of aggregate computation time. Acquiring the computational resources to execute these workflows poses many challenges for application developers. Although the grid provides ready access to large pools of computational resources, the traditional approach to accessing these resources suffers from many overheads that lead to poor performance when used for workflow execution. We describe how resource provisioning techniques such as advance reservations, multi-level scheduling, and cloud computing can be used to reduce scheduling overheads and improve application performance. We explain the advantages and disadvantages of these techniques in terms of cost, performance and usability.
