Analysis and Visulizaiton tools for Lattice QCD

We developed a toolkit for analysis and visualization of QCD data.The analysis tools include a web based application for extracting data in real time from log files, computing autocorrelation, moving averages, bootstrap samples and bootstrap errors from user provided functions, non-linear Bayesian correlated fits, make the relative plots, and facilitate collaborative work.The visualization tools include standard QCD algorithms with the additional ability to save intermediate steps of the computation in parallel in the VTK file format for real time visualization of on-going computations.To demonstrate, we made visualizations showing the convergence of the MinRes inverter for different sources, evolution of the topological charge under different algorithms for dynamical fermions, energy density in space in the presence of static quark-antiquark, and heavylight wave functions.Our toolkit is self contained and works in cooperation with many existing QCD code.
