Kristy Kallback-Rose joined the NERSC Storage Systems Group in early 2017. In recent years, Kristy has worked with geographically distributed filesystems and archival storage, including GPFS and HPSS, primarily at Indiana University. Prior to that she worked in a variety of roles including grid computing in support of the ATLAS project, databases, development and instruction. Kristy has undergraduate degrees in Japanese and Physics and an masters in Physics and is pleased to be working at NERSC in support of scientific research.

Wrangling data at a scientific computing center can be a major challenge for users, particularly when quotas may impact their ability to utilize resources. In such an environment, a task as simple as listing space usage for one's files can take hours. The National Energy Research Scientific Computing Center (NERSC) has roughly 50 PBs of shared storage utilizing more than 4.6B inodes, and a 146 PB high-performance tape archive, all accessible from two supercomputers. As data volumes increase exponentially, managing data is becoming a larger burden on scientists. To ease the pain, we have designed and built a “Data Dashboard”. Here, in a web-enabled visual application, our 7,000 users can easily review their usage against quotas, discover patterns, and identify candidate files for archiving or deletion. We describe this system, the framework supporting it, and the challenges for such a framework moving into the exascale age.
