Stephen McNally is the Operations Manager for the National Center for Computational Sciences. In this role, he oversees the day-to-day activities of the multi-programmatic computing center. Stephen began working in high-performance computing (HPC) in 2009 as a Linux systems administrator supporting the Kraken supercomputer. Prior to HPC, Stephen served as an IT professional in the automotive and healthcare industries. He received business degrees, including an MBA from Tennessee Technological University in 2013. Stephen’s educational background in business coupled with his highly technical experience in HPC provide unique insight that is well-suited for managing the operations of a leadership computing facility.
Stephen serves as a guest lecturer for various classes in and around the greater Knoxville area. His primary speaking role is associated with the University of Tennessee, Knoxville course titled, “Introduction to Data Centers”. This course is taught primarily by data center experts from ORNL in partnership with the University of Tennessee, Knoxville. He teaches the first classes of the semester surrounding the strategy required in building, maintaining, and operating a data center.
Stephen enjoys serving in the local community and does so through various non-profit organizations, his church, and local government groups. In 2016, he began working with various economic development firms and organizations to ensure that Tennessee continues to stand tall as a national leader in economic development. With his civic duties, Stephen also participates in the IEEE and iMasons professional societies.
