Biographical Sketch

Tina Declerck leads the NERSC System’s Department that is composed of the Computational Systems, Security and Networking, Operations Technology, and Building Infrastructure groups. Her accomplishments include managing the configuration, installation, and acceptance of the NERSC-9 (Perlmutter) system - expected to arrive in early 2021, and project lead on NERSC-8 (Cori). Tina has experience with almost all of the systems installed at NERSC since 1996 as a system analyst since its move to Lawrence Berkeley National Lab from Livermore. During a short hiatus from NERSC (2001-2006) she focused on storage startups.  Prior to joining NERSC in 1997, she worked at The Liposome Company and was an officer in the USAF.

As the DOE Office of Science's mission computing facility, NERSC will follow this roadmap and deploy these new storage technologies to continue delivering storage resources that meet the needs of its broad user community. NERSC's diversity of workflows encompass significant portions of open science workloads as well, and the findings presented in this report are also intended to be a blueprint for how the evolving storage landscape can be best utilized by the greater HPC community. Executing the strategy presented here will ensure that emerging I/O technologies will be both applicable to and effective in enabling scientific discovery through extreme-scale simulation and data analysis in the coming decade.
