Description
When doing an HEP analysis, physicists typically repeat the same operations over and over while applying minor
variations. Doing the operations as well as remembering the changes done during each iteration can be a very
tedious process. HEPTrails in an analysis application written in Python and built on top of the University of Utah's
VisTrails system which provides workflow and full provenance tracking for scientific analysis. HEPTrails adds
substantial extension to VisTrails in order to accommodate HEP analysis. These extensions include: a streaming
workflow engine and with very fine grain modules, a lab notebook style presentation window capable of showing
preliminary results, and local area distributed computing. Although HEPTrails is still in early development, it already
shows great promise in aiding HEP physicists.
