Dong H. Ahn is AI and Data Infrastructure Architect (distinguished engineer) at NVIDIA. He strives to extend his 20+ year experiences on extreme-scale HPC and NVIDIA's first Ominverse cloud systems to scale AI/Data infrastructures and training workflows to unprecedented cloud data-center levels. His current focus includes building an automated productivity service that can detect, isolate and remediate anomalies for extreme-scale Generative AI training workflows.

Prior to joining NVIDIA, Dong has worked for the Development Environment Group (DEG) in Livermore Computing (LC) between 2001 - 2022. In his last capacity he led the next-generation computing enablement (NGCE) project within the ASC ATDM program and led the development of flux-framework which now manages the world-largest exascale supercomputer, El Capitan. He also architected an extreme-scale debugging strategy that conceived the Stack Trace Analysis Tool (STAT), a 2011 R&D 100 Award winner, the PRUNERS Toolset, a 2017 R&D 100 Award finalist, and Flux (a next-generation workload manager), a 2021 R&D 100 Award winner. 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), as a research assistant.
