VisIt

Description

VisIt is a free, open source, platform-independent, distributed, parallel visualization tool for visualizing data defined on two- and three-dimensional structured and unstructured meshes. VisIt’s distributed architecture allows it to leverage both the compute power of a large parallel computer and the graphics acceleration hardware of a local workstation. VisIt’s user interface is often run locally on a Windows, Linux, or macOS desktop computer while its compute engine component runs in parallel on a remote computer. VisIt’s distributed architecture allows VisIt to visualize simulation data where it was generated, eliminating the need to move the data to a visualization server. VisIt can be controlled by its Graphical User Interface (GUI), through the Python and Java programming languages, or from a custom user interface you develop yourself. More information about VisIt can be found online at https://visit.llnl.gov/.

VisIt is a scalable production visualization and analysis tool widely used throughout DOE. It is designed to support visualization at scale.

Impact, Sustainability, and Quality

Property	State
Impact	VisIt is widely used throughout DOE for scalable production visualization and analysis. It is deployed at all major DOE computing facilities and is used daily for analysis and visualization.
Sustainability	The fundamental capabilities that VisIt provides are widely used and have a fairly sustainable funding stream. The support for ASCR compute facilities and applications is dependent on DOE funding.
Quality	VisIt has well-established quality metrics, software, and testing processes.
