Biographical Sketch

Tina Declerck recently returned to the NERSC’s Computational Systems Group after working there from 1997 through 2001. In her previous tenure at NERSC she managed the PDSF and Cray J90 SV1 clusters. During her hiatus, she worked at Sistina Software, the company that developed the Global File System (GFS) and was later bought by Red Hat. At Sistina, Tina was in charge of growing and managing the customer support team. At 3Ware, which manufactures SATA RAID controllers, she defined new product features, acted as the primary interface between the field support and engineering teams, provided technical training to resellers, and worked on I/O performance and tuning. Now back at NERSC, Tina is the system lead for the SGI Altix named DaVinci, and she provides secondary support on Franklin, the Cray XT4.

"Storage 2020: A Vision for the Future of HPC Storage", October 20, 2017, LBNL LBNL-2001072,

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.
