Data Management for Exascale Scientific ApplicationsMy current research focuses on optimizing coupled scientific workflow applications on high-end computing platforms. My work enables in-situ/in-transit execution of user-defined data analysis operations as part of the coupled simulation-analysis workflow, and employs the data-aware task mapping and scheduling approach to reduce the amount of network data movement.
