Gary Grider, HPC Division Leader, ALDSC/HPC-DO, is the leader of the High Performance Computing (HPC) Division at Los Alamos National Laboratory (LANL). As division leader, Gary is responsible for all aspects of HPC technologies and deployment at the Lab. Additionally, Gary is responsible for managing the research and development (R&D) portfolio for keeping the new technology pipeline full to provide solutions to problems in the Lab’s HPC environment, through funding of university and industry partners. Gary is also the US Department of Energy data storage, IO, and data management national co-coordinator. In this role, Gary helps manage the US government investments in data management, mass storage, and IO. Gary has 24 granted patents and over 30 patent applications in the data storage area and has been working in HPC and HPC-related storage since 1984.

Steve Poole, Chief Architect, ALDSC/HPC-DO, is the chief architect for all future systems.

Howard Pritchard is a research scientist at LANL. He is the team lead for LANL’s HPC application readiness team. His areas of research include investigation of the performance of mission-critical applications on future systems, with a focus on architectures promising efficient computing at scale. Another area of his research is development of extensions to the MPI Standard as part of the Exascale Computing Project, as well as development and support of the Open MPI implementation of MPI. He is also active in the support and development of networking middleware software, including OpenUCX, OFI libfabric, and OpenSHMEM.

Reid Priedhorsky is a staff scientist at LANL. Before working at the Lab, he was a research staff member at IBM Research. He holds a Ph.D. in computer science from the University of Minnesota and a B.A., also in computer science, from Macalester College. Reid’s focus is on large-scale data analysis from both a system and an application perspective. Recent lines of research include using social media and web traffic to monitor and forecast the spread of disease as well as developing technology to bring data-intensive computing and user-defined software stacks to existing HPC systems. 

David Bonnie is a storage architect with a background in scalable storage systems and software development. He contributed to the development of OrangeFS/PVFS2 and holds a deep interest in understanding current and future storage hardware and software. David is currently the campaign storage, future archive, and enterprise backup technical lead for the HPC Division at LANL, positions that include leading integration, development, and production support efforts for LANL’s pre-archive, archive, and backup tiers. He is integral in the development and deployment of these solutions, which are designed to serve the needs of ever-growing datasets paired with spiraling bandwidth and reliability challenges.

Dominic Manno is a scientist with a background in storage systems and software development with an emphasis in HPC. He is currently the file systems technical lead for the HPC Division at LANL. This work includes leading design, development, integration, and support efforts for HPC file systems deployed to support simulation science at LANL. Mr. Manno also co-leads a subset of storage research efforts at LANL’s Ultrascale Systems Research Center, where his work is focused on next-generation storage systems.

Tim Randles has been working in scientific, research, and HPC for many years, first in the Department of Physics at the Ohio State University, then at the Maui High Performance Computing Center, and most recently as a member of the HPC Division at LANL. His current work is focused on the convergence of the high performance and cloud computing worlds, Linux containers, and next-generation HPC system integration. 

Samuel Gutierrez is a computer scientist in the HPC Division at LANL. Gutierrez is from the northern New Mexico village of El Pueblo. He attended New Mexico Highlands University in nearby Las Vegas, New Mexico, where he received his bachelor of science degree in computer science. He received his master’s degree and Ph.D. in computer science from the University of New Mexico in 2009 and 2018, respectively. Gutierrez’s research is focused primarily on the design and construction of low-level software systems that allow parallel and distributed programs to run more efficiently on supercomputers.

Brad Settlemyer is currently a senior scientist in LANL's HPC Design group. He received his Ph.D. in computer engineering from Clemson University in 2009 and works as a researcher in the field of HPC storage systems. He currently leads the storage systems research efforts within the Lab's Ultrascale Research Center, and his team is responsible for designing and deploying state-of-the-art storage systems for enabling scientific discovery. He is the primary investigator on projects ranging from ephemeral file system design to long-term molecular information storage. He has published papers on emerging storage systems, long-distance data movement, network and storage modeling, and storage system algorithms.

Mike Mason is the team leader for the Monitoring, Data Analytics and Security Development Team in the HPC Division at LANL. He is responsible for monitoring the full HPC Data Center, from facilities to clusters and infrastructure. Mike and his team work on many varied development projects, including web frontends, security tools for compliance scanning, and customized Splunk applications for HPC. Mike received bachelor degrees in computer science, mathematics, and physics from The University of New Hampshire and a Masters in Physics from Texas A&M University. He has been working as a scientist at LANL since 2011.

Nathan DeBardeleben joined LANL in 2004 after finishing his Ph.D. in computer engineering from Clemson University with a focus on parallel computing. He is a senior research scientist and the co-executive director of the Ultrascale Systems Research Center (USRC) at LANL. Nathan's research focuses on resilience and reliability of supercomputers, which often includes large-scale data analytics and machine learning. He leads a team that irradiates semiconductors in neutron beams, builds software fault injectors, and develops methods and models for evaluating current and future HPC systems. Nathan works extensively with universities and industrial partners and mentors several students concurrently.

Wendy Poole is a scientist in the HPC Division at LANL. Wendy is currently working on projects with external customers in the following areas: OpenSHMEM, computing in the network, and OpenUCX and high performance network algorithms. Her interests are in quantum information sciences and mathematics.
