Reproducing research with the Marchenko method and inversion with the SEISCOPE toolbox

Workshop 15: Friday, 7 June 
Conveners:

Jan Thorbecke (Cray)
Joeri Brackenhoff (TU Delft)
Ludovic Métivier (Univ. Grenoble Alpes)
Romain Brossier (Univ. Grenoble Alpes)

Description:

The workshop is based on two published papers:

-1- Implementation of the Marchenko method.

Jan Thorbecke, Evert Slob, Joost van der Neut, Joeri Brackenhoff, and Kees Wapenaar, 2017, Geophysics, Vol. 82(6), WB29-WB45.



-2- The SEISCOPE optimization toolbox: A large-scale nonlinear optimization library based on reverse communication.

Ludovic Métivier and Romain Brossier, 2016, Geophysics Vol. 81(2), F1-F15.

The aim of the workshop is to reproduce the results in two specific papers with the open-source software bundled with each paper. The attendees will be working in groups to reproduce the research. 

The workshop, split into a morning and afternoon session, will start with defining a common ground to make sure that everybody understands the physics and is familiar with the vocabulary. 

Afterwards, people will work in teams (3-5 people per team) to reproduce the research. For each paper there will be a few tasks/problems defined that can be solved with the provided software. The goals of these problems is that the attendants start to understand the underlying algorithm and can use the software. These tasks must be real challenges: some of the teams should not be able to solve the challenge in the given time.

After a given time (2-3 hours), each team presents their solution of the first problem in about 10 minutes. 

For the afternoon session, the teams are re-organised such that everybody works with all different people. People are not allowed to sit in a team with the same persons as during the first assignment. 

The goal and outcome of the workshop is that attendees will bring home new software tools they understand and can use, have learned new skills, and have met new people they worked together with on solving the problems. 

 

Required skills to attend the workshop:

- Compile, read and write C/Fortran code and run programs in Linux.
- Good understanding of Geophysics.
- Bring a laptop than can run Linux and ssh to a compute resource.
