ScrubJay: A Bird's-Eye View of Computing Performance December 10, 2018

ScrubJay, an open-source performance data analysis tool, helps ensure that the Laboratory’s HPC center lives up to its name. Check out this new writeup in LLNL’s magazine, Science & Technology Review. Fork the repo on GitHub.

ScrubJay is an intuitive, scalable framework for automatic analysis of disparate HPC data. ScrubJay decouples the task of specifying data relationships from the task of analyzing data. Domain experts can store reusable transformations that describe the projection of one domain onto another. The program also automates performance analysis. Analysts provide a query over logical domains of interest, and ScrubJay automatically derives the needed steps to transform raw measurements. This process makes large-scale analysis tractable and reproducible, thus providing crucial insights into HPC facilities.
