2011 PyLith and GALE Tutorials at Earthscope

Gale Tutorial - Long-Term Tectonics

• Instructor: Walter Landry (CIG)

Gale is a 2D/3D parallel code that solves problems in orogenesis, rifting, and subduction with a variety of boundary conditions, including free surfaces and coupling to surface erosion models. Gale is bundled with a number of rheologies and extensive documentation, and is extensively benchmarked. Precompiled binaries make it easy to start using Gale on Windows, Mac, or Linux laptops and desktops. Thorough installation notes allow users to then install Gale on the largest supercomputers and run the same input files.

During the session, participants will be given background theory, an overview of the code including its strengths and weaknesses for solving geodynamic problems, and instruction on downloading and running these codes (including running them on the NSF TeraGrid), and post-processing (visualizing) the results. As time permits, the workshop will also cover how to implement new rheologies and custom surface processes in Gale.

Gale code

We request all participants to download and build the Gale code on your laptops before the workshop, in order to maximize time spent on using the code in classroom examples. Link to the code, binaries and associated manual can be found Here.

Walter Landry has put together a "Troubleshooting" PDF that covers some of the common flags users may find when building the code, and suggestions for clearing them. Gale Installation
