Kathryn Mohror is a computer scientist at the Center for Applied Scientific Computing ( CASC) at Lawrence Livermore National Laboratory ( LLNL). Kathryn’s research on high-end computing systems is currently focused on scalable fault tolerant computing and performance measurement and analysis. Her other research interests include scalable automated performance analysis and tuning, parallel file systems, and parallel programming paradigms. Kathryn has been working at LLNL since 2010. Kathryn is a member of the Exascale Computing Technologies (ExaCT) LDRD project and works closely with the Development Environment Group ( DEG) in Livermore Computing ( LC). Her current research focuses primarily on the Scalable Checkpoint/Restart Library ( SCR), a multi-level checkpointing library that has been shown to significantly reduce checkpointing overhead. Kathryn received her Ph.D. in Computer Science in 2010, an M.S. in Computer Science in 2004, and a B.S. in Chemistry in 1999 from Portland State University ( PSU) in Portland, OR.
