Dakota

Information and discussion on using Dakota in CSDMS.

Dakota is a software toolkit developed at Sandia National Laboratories that provides an interface between models and a library of analysis methods, including support for sensitivity analysis, uncertainty quantification, optimization, and calibration techniques.

Todo:

• More intro to Dakota. Include verbiage about the need for UQ?
• An overview of how Dakota works. Do I really want to write this up?
• A simple example of using Dakota. Another transcluded page.

Setting up Dakota on beach

Dakota 6.1 is installed on the CSDMS HPCC, beach.colorado.edu. To use Dakota on beach, you'll need to modify your user environment. (This only needs to be done once.)

In your favorite text editor, open your .bashrc file (located in your home directory) and add the following lines to the bottom of the file:

PATH=$PATH:/usr/local/dakota/bin:/usr/local/dakota/test
export LD_LIBRARY_PATH=/usr/local/dakota/bin:/usr/local/dakota/lib

Save the file, logoff from beach, then login again. Dakota will now be available for use. Check with:

$ dakota --version
Dakota version 6.1 released Nov 15 2014.
