Dr. Lange joined ORNL in 2021 as a Senior HPC Systems Scientist, and will be working on evaluating and planning the system software architectures for current and future Oak Ridge Leadership Computing Facility systems.
Before coming to ORNL, Jack was an Associate Professor of Computer Science in the School of Computing and Information at the University of Pittsburgh. Prior to joining the faculty at Pitt, Jack received his Ph.D. from Northwestern University. During his career in academia, Jack’s research has focused on systems software for high performance computing environments, including high performance virtual machine managers (VMMs) and hypervisors, novel operating systems (OS) architectures, shared memory frameworks, and overlay networks. This work has served as the foundation for several Department of Energy research projects including the Hobbes Exascale operating system and runtime (OS/R.)
