Standard Model of Scientific Computing

All users must do these things...

Write an input file in a format reminiscent of a dead language

Define the Problem

Manually launch jobs on impressively terrifying machines

Run the Simulator

Analyze simulation output in its most raw and unlimited form

Analyze Output

Store data... somewhere!

Archive Output

Super-users think these are easy tasks, but most users are overwhelmed!

A ICE Model of Scientific Computing

It would be better to have a computer program handle all of that...

Define the Problem

Run the Simulator

User

Most of the stuff we need to do can be encapsulated for ease of use and/or automated entirely with improvements.

What is VisIt?

“… an open source, interactive, scalable, visualization, animation and analysis tool.” “… a distributed, parallel visualization and graphical analysis tool for data defined on 2D and 3D meshes.” “… originally developed… to visualize and analyze the results of terascale simulations… [but] has also proven to be well suited for visualizing smaller scale data...” “… capabable of visualizing data from over 120 different scientific data formats.”

Future Work

•  Time slider for files with time-varying data

•  Capabilities added to workbench

•  ICE moving to Eclipse 4

•  ICE initial contribution review complete, starting migration next week

•  Increase users and further collaboration with Science IWG

•  Deeper discussion of collaborative analysis at EclipseCon NA 2015
