Scientific Computing Summer Workshop 3: Introduction to Arches and the Uintah Framework.

Wednesday, July 14th, 2010.

Abstract: The Arches large-eddy simulation code is an object-oriented C++ code developed to simulate turbulent combustion as a part of the C-SAFE program at the University of Utah. Arches is a component built within in the Uintah Computational Framework (UCF), a C++ framework enabling parallelization to thousands of processors. The Arches code is complex and multi-faceted, and as such requires the user to have a thorough understanding of both the UCF and the code's algorithm in order to begin developing within Arches. This workshop is intended to give potential Arches users and developers a gentle introduction to the UCF concepts required to understand what Arches is doing, as well as a higher-level algorithmic view of the Arches code.

It is recommended that users check out a copy of Uintah from SVN by running the following command at a command prompt:

$ svn co https://gforge.sci.utah.edu/svn/uintah/trunk ~/uintah

This will create a copy of the Uintah framework in a folder called "uintah" in your home directory. Checking out the code from the SVN repository will take a few minutes. The Arches component, if you are interested in exploring ahead of time, is located at the following location:

$ cd ~/uintah

$ cd src/CCA/Components/Arches
