SC20 Is Everywhere We Are

SC20 Virtual Platform
Dong H. Ahn is a computer scientist. He has worked for Livermore Computing at LLNL since 2001 and currently leads the next-generation computing enabling (NGCE) project within the ASC Program. During this period, Dong has worked on several code-development-tools resource management and scheduling software projects with a common goal to provide highly capable and scalable ecosystems for large computing systems. Towards this goal, he has architected an extreme-scale debugging strategy that conceived the Stack Trace Analysis Tool (STAT), a 2011 R&D 100 Award winner, and the PRUNERS Toolset, a 2017 R&D 100 Award Finalist. His current interest includes scalable approaches to managing the adverse impacts of non-determinism in concurrent execution, and to HPC resource and job management. Before he joined LLNL, Dong earned a Master’s degree in Computer Science in 2001 from the University of Illinois at Urbana-Champaign and had worked for National Center for Supercomputing Applications (NCSA).
