What is QuickCompare?

QuickCompare is an offshoot of QuickView. Instead of presenting a single simulation, QuickCompare contrasts two or more simulations that use the same horizontal mesh (and hence the same connectivity file). Plots can be shown for the user-selected physical quantities themselves as well as differences and/or relative differences with respect to a control simulation. Like QuickView, QuickCompare can present multiple variables simultaneously.

Key Features

• Intuitive, minimalist interface tailored for Earth system modeling.
• Multi-variable visualization.
• Differences and relative differences displayed with colors that can facilitate interpretation.
• Persistent sessions—pick up where you left off.
• Support for EAM v2, v3, and upcoming v4 output formats as well as the E3SM land model ELM's input and output files on ne*pg2 grids.

Project Background

The lead developer of QuickView version 2 is Will Dunklin at Kitware. Other key contributors include Sebastien Joudain, Patrick O'Leary, Berk Geveci, and Dan Lipsa at Kitware as well as Hui Wan and Kai Zhang at Pacific Northwest National Laboratory.

QuickCompare is a product of an interdisciplinary collaboration supported by the U.S. Department of Energy Office of Science’s Advanced Scientific Computing Research (ASCR) and Biological and Environmental Research (BER) via the Scientific Discovery through Advanced Computing (SciDAC) program.

The development of QuickCompare used resources of the National Energy Research Scientific Computing Center (NERSC), a U.S. Department of Energy User Facility.
