ORNL/Frontier Showcase

This is a website for the Showcase for the Oak Ridge National Laboratory's Leadership Computing Facility and the Frontier supercomputer. This is an opportunity for you to have a site visit and virtual tour of both the ORNL infrastructure and the Frontier system. The showcase will be held over a few days, a few months apart. The first day was a deep focus on the ORNL infrastructure/building, held on July 27th. The second day will be a deeper focus on the Frontier supercomputer at a later date (to be determined). Recordings of the July 27th showcase presentations are included below.

Keynote: Dr. Bronson Messer, Director of Science, National Center for Computational Sciences, Oak Ridge National Laboratory (ORNL) will provide his perspective on the system architecture and the notable scientific outcomes that this type of system can support as a critical Department of Energy (DOE) modeling/simulation instrument.

AGENDA:

Introduction, Torsten Wilde

Keynote, Bronson Messer

Facility Scope overview, David Grant

Electrical deep dive, Rick Griffin

Mechanical deep dive, David Grant

Controls deep dive, Chad Ator

The next program will follow-on with a deeper technical understanding of the power and energy measurement and management capabilities from within the system stack. This will include leveraging community-driven efforts within the HPC software stack (e.g., PowerAPI).

Besides prepared presentation material, there will be a lot of opportunities for questions and discussion.

Bronson Messer is a Distinguished Scientist and Director of Science at the Oak Ridge Leadership Computing Facility (OLCF) at ORNL. He is also a Joint Faculty Associate Professor in the Department of Physics & Astronomy at the University of Tennessee. His primary research interests are related to the explosion mechanisms and phenomenology of supernovae (both thermonuclear and core-collapse), especially neutrino transport and signatures, dense matter physics, and the details of turbulent nuclear combustion.

Dr. Messer is a member of the American Astronomical Society, the American Physical Society, and the American Association for the Advancement of Science.

Rick Griffin was the manager for one of the municipal electric utilities in the TVA system for approximately 5 years, during which time he served on a TVPPA research and development board. The remaining 40 years of his career has been spent as a facility design engineer for electrical power distribution systems. During the first 20 years of this time he has generated designs for large supervisory control and data acquisition (SCADA) systems, supported large scale laser isotope separation plant design and evaluations, supervised multidiscipline engineering group, generated designs and supported operations for a contaminated waste processing plant, and generated designs and supported operations for demolition of two large gaseous diffusion plant. For the last 21 years, he has been employed at ORNL and solely dedicated to the effort to provide facilities for large scale computer systems. In this role, he has generated electrical, networking, fire alarm, access control and other requirements for large computer facilities, interfaced with researcher and computer customers to translate their requirements into contractual requirements for new buildings, rooms, and support facilities, performed designs for tenant improvements, supported operations of computer facilities by investigating off normal events, evaluating effectiveness of installed systems to identify improvements that can be made, generated floor layouts for very large computer systems, generated installation requirements for more than 20 high performance computers ranging in load from 0.5MW to 30MW, generated design concepts for 30MW 13.8kV power supply expansion to support Frontier computer installation, supported electrical systems commissioning activities for large computer systems, performed power quality studies and implemented changes to increase IT equipment availability, and modeled electrical distribution systems for HPCs.

BS EE from Auburn University, PE in State of Tennessee

Chad Ator is a project engineer with Ivey Mechanical. He is responsible for engineering, project controls and commissioning. He has worked on several projects at Oak Ridge National Laboratory. He has a BS in Mechanical Engineering from Tennessee Technological University.

David Grant graduated from the University of Tennessee in 2003 with a B.S. in Mechanical Engineering. He has been at the Oak Ridge National Laboratory (ORNL) since 2009 and is a senior technical staff member. While at ORNL he has been involved with the design, construction, and operation of the mechanical systems supporting ORNL's 80,000SF+ of data centers which house the Summit and Frontier High Performance Computer Systems among others. He is currently a co-chair of the Energy Efficient HPC Working Group Infrastructure sub-team and is a corresponding member of the ASHRAE TC9.9. David is a registered Professional Engineer with the State of Tennessee and is a Certified Energy Manager (CEM - from the Association of Energy Engineers (AEE)) and a Data Center Energy Practitioner – Specialist (DCEP - from the Department of Energy (DOE)).

Torsten Wilde (Ph.D.) is a system architect for HPC system monitoring and system power and energy management at Hewlett Packard Enterprise (HPE). His research activities are related to high volume, high frequency data collection and analytics for improved IT operations as well as dynamic power management. Torsten has published more than two dozen research papers mainly related to power and energy usage and improvement in High Performance Computing. Torsten received his MSc in parallel and scientific computation from the University of Liverpool, UK, and his MSc in Computer Engineering from the University of Applied Sciences in Berlin, Germany. He received his Ph.D. in computer science from the Technical University of Munich, Germany, in 2018.
