Bio
Dr. William F Godoy joined ORNL in 2016, and is currently a Senior Computer Scientist in the Computational Science and Mathematics Division, CSMD. A native of Peru, his background is in Mechanical Engineering with research interests on high-performance computing (HPC), programming models, scientific software, workflows, and AI for HPC.
Dr. Godoy obtained his PhD (2009) and MS (2006) degrees from the State University of New York at Buffalo, working under the supervision of Dr. Paul E. DesJardin on 3D radiative transfer parallel computational models. Before ORNL, he worked as a Senior Software Engineer at Intel Corporation (2012-2016) and a postdoctoral fellow at NASA Langley (2009-2012) on Jacobian-Free Newton Krylov methods and GPU solutions for radiative transfer.
At ORNL, Dr. Godoy contributed to the US Department of Energy (DOE) Exascale Computing Project (ECP) as (i) the architect and core developer of ADIOS 2, the Adaptable Input Output System version 2, (ii) contributor to the QMCPACK software, and (iii) researching the LLVM-based Julia language for HPC under PROTEAS-TUNE - which led to a best paper at WORKS SC23 and a first paper on applying large language models (LLMs) to HPC. He also worked on improving the file loading times and performance of data reduction workflows impacting users at ORNL neutron science facilities: SNS and HFIR.
Dr. Godoy is currently funded by the US DOE Advanced Scientific Computing Research (ASCR) serving as co-PI of S4PST and member of PESO, funded by the ASCR Next Generation of Scientific Software Technologies project, as co-PI of a EXPRESS project on power models for novel hardware, and as co-PI of the Ellora AI4Science project leveraging LLMs for HPC software. He also serves as a mentor on several internship programs and technical committees. He is a senior member of IEEE, and a member of ACM.
