Weikuan Yu, Professor in the FSU Department of Computer Science, has been awarded a grant of $95K for research on scientific workflow characterization and optimization from Lawrence Livermore National Lab (LLNL). The project, titled as “Enabling Efficient Checkpoint/Restart for Scientific Workflows“, aims to characterize the performance critical stages of big scientific workflows and propose efficient checkpoint/restart techniques to preserve the execution progresses that have been achieved in a long-running scientific workflows. This project continues Dr. Yu’s decade-long productive collaboration with Dr. Kathryn Mohror at LLNL and builds on top of the prior project of I/O characterization for the specialized VAST file system that supports I/O disaggregation. Dr. Yu and his team plan to develop a checkpoint/restart library to support efficient and fault-tolerant scientific workflows.
