Madagascar School and Workshop on Reproducible Computational Geophysics



Day 1: Friday, July 20, 2012
8:00-9:00 Coffee/pastries/installation

Bring your laptop and get help getting Madagascar installed.

9:00-10:15 Introduction (Sergey Fomel)

The Madagascar open-source project has been in public existence for six years. Madagascar provides a complete environment for organizing one's research, from new software development to running computational experiments to publishing the computational results in papers and reports, archiving them for future usage, and sharing them with colleagues or sponsors. The introductory presentation will describe the history of the project, the Madagascar components and design principles, and plans for future development.

10:15-10:30 break

9:00-12:00 Seismic wavefield imaging and Writing Research Papers (Paul Sava)

The theoretical part of this module provides an overview of reverse-time imaging methodology applied to wavefield seismic data. The main technique discussed is reverse-time migration developed under the single-scattering assumption. The applied part demonstrates this technique on a complex geologic model using Madagascar codes in a fully reproducible setup. We will conclude by generating reproducible documents constructed using LaTeX.

12:00-1:00 Lunch
1:00-1:45 Developing your own programs in Madagascar (Jingwei Hu)

There are many programs already built into the Madagascar project, but if you use Madagascar long enough you will eventually run into a problem that you cannot solve using only provided codes. Fortunately, Madagascar has a variety of programming language APIs already built, that allow you to: design, code, and integrate your programs into the Madagascar framework. This session will discuss an overview of the Madagascar APIs, and then focus in particular on the C++ APIs. By the end of the session, you should have a good starting point for developing your own codes, and adding them to the growing library of open-source software available in Madagascar.

1:45-2:30 Python and Graphical User Interfaces (Sergey Fomel)
2:30-2:45 break
2:45-3:30 Parallel processing with Madagascar (Esteban Díaz)
3:30-4:15 Contributing your code to Madagascar (Sergey Fomel)
4:15-5:00 Discussion

Open Q&A session and discussions on the future development of Madagascar
