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

	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 with emphasis on modern imaging conditions which enable migration velocity analysis and amplitude-versus-angle analysis. The applied part demonstrates this technique on a complex geologic model using Madagascar codes in a fully reproducible setup.<br><br>		The theoretical part of this module provides an overview of reverse-time imaging methodology applied to wavefield seismic data.

	Why Madagascar was easy for me? The art of the Madagascar template! In a year, I managed to write 7-8 papers using Madagascar, and the papers are still coming. Considering that I have used SU (Seismic Unix) all my life and taking into account my not-so-young age, I think Madagascar was good to me. In the presentation, I will share my experience (no Python background knowledge is needed!) and share some insights on how to use Madagascar efficiently.		Why Madagascar was easy for me?

	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 and Python 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.

	Back in the 1980's we had a lot of different hardware graphics devices to support. Now we are back to the future... the challenge today is to support a multitude of different software graphics devices. The same structures that were useful then are useful now. I will talk about the philosophy of vplot and how it is as useful today as it was when it was devised. I will also show some vplot tricks you can use to astound your friends.

Major available styles of plots will be explained as long as the mechanism of creating figures in reproducible fashion for papers and presentations. The second part will be a tutorial for using Madagascar in a high-performance environment. Different types of such environments will be described and principal approaches to handling parallel problems with Madagascar will be unfolded. This module will specifically address how to run data-parallel tasks and how to create Madagascar programs with MPI and GPU(CUDA) routines.
