Scott joined ORNL in 2011. He is a Distinguished R&D Staff Member and he currently serves as the Chief Technology Officer for the National Center for Computational Science and the Oak Ridge Leadership Computing Facility. Scott focuses on compute, memory, and interconnect technology trends to understand how to optimize existing systems such as Frontier, how to prepare for next generation systems. Scott and the OLCF team are defining the requirements for OLCF-6, the system that will follow Frontier. His interests include resource heterogeneity within processors, within nodes, and across the system; processor architectures (e.g., CPU, GPU, FPGA, coarse-grained reconfigurable arrays); memory architectures and hierarchies; persistent memory; interconnects (e.g., PCIe, CXL, UCIe, InfiniBand, Ethernet); system scheduling; resilience; and system monitoring.
For Oak Ridge Leadership Computing Facility’s (OLCF) Frontier project, Scott is the Technical Project Officer (TPO). Scott reprises this role for the OLCF-6 project.
Scott was very involved in DOE’s Exascale Compute Project. He served as DOE’s Technical Representative for AMD’s FastForward-2 Node Architecture project and for AMD’s PathForward project. He also served as the lead for ECP’s HPCM and Slingshot Test and Evaluation effort.
