Dong H. Ahn

Dong H. Ahn received the master’s degree in computer science from the University of Illinois at Urbana Champaign in 2001. He has been working for the Development Environment Group at Lawrence Livermore National Laboratory since 2001. During this period, he has worked on several code-development-tools projects with a common goal to provide highly capable and scalable tools ecosystems for large computing systems. Toward this goal, he has negotiated and managed key software development contracts to improve the capabilities and scalability of the TotalView parallel debugger, architected LLNL’s extreme-scale debugging strategy that conceived the Stack Trace Analysis Tool (STAT). He is a 2011 R&D 100 Award winner, and has invented novel software infrastructure technologies as well as led interactions with vendors to enable this strategy. His current interest includes scalable approaches to massively scalable dynamic loading, to managing the adverse impacts of nondeterminism in concurrent execution, and to next-generation resource management. Prior to joining LLNL, he worked for the National Center for Supercomputing Applications (NCSA). He is a member of the IEEE Computer Society and the ACM.
