SUMMARY:Missing the Trees for the Branches: Graphical-Scripting Interactio
 n with Large-Scale Calling Context Trees
DESCRIPTION:ACM Student Research Competition: Graduate Poster, ACM Student
  Research Competition: Undergraduate Poster, Posters\n\nMissing the Trees 
 for the Branches: Graphical-Scripting Interaction with Large-Scale Calling
  Context Trees\n\nScully-Allison\n\nIn large scale performance analysis of
  HPC code, there is a tension between the visualizations provided by autom
 ated tools and the flexibility afforded by custom scripting. For calling c
 ontext trees (CCT), node-and-link visualizations give users a view of perf
 ormance data that corresponds to their mental model. Unfortunately, while 
 current scripting workflows support the writing of code, they are not well
  supported by existing visualizations. GUI-based tools often restrict user
 s to rigid modes of interaction. Furthermore, many general purpose visuali
 zation libraries are not well configured to support the complex data colle
 cted by HPC profilers, do not scale well to fit real HPC datasets, and oft
 en require exporting and viewing visualizations in a context divorced from
  where the code is developed. To ease this tension and support modern anal
 ysis workflows, we use human-centric design methodologies to marry scripti
 ng and graphical interaction paradigms into a scalable, interactive CCT vi
 sualization embedded in Jupyter notebooks.\n\nTag: In-Person Only\n\nRegis
