2022 SPECFEM virtual workshop for users

(go here for information on the developers workshop in Toronto)

A virtual workshop for learning to use SPECFEM, open-source software for seismic wave propagation and seismic imaging in 2D and 3D. Codes featured include SPECFEM2D, SPECFEM3D, Seisflows, and Pyatoa.

DAY 0 [Tues] October 4, 12:00–13:00 US Eastern time [verifying software installs only]

DAY 1 [Wed] October 5, 12:00–16:00 US Eastern time

DAY 2 [Thu] October 6, 12:00–16:00 US Eastern time

DAY 3 [Fri] October 7, 12:00–16:00 US Eastern time

Where: zoom

Agenda: here (includes background reading)

Registration: If interested, please fill out this survey to provide your basic information.

Format: Participants will install and run software on their own machines, then interact with hosts and other participants via zoom.

Requirements: Participants will need access to a computer and have permission to install docker and also the software container for the workshop.

Costs: none

Organizer: Carl Tape

Host: Bryant Chow

Starting point: docker install, download software container

Invited talks: Jeroen Tromp, Daniel Peter, Qinya Liu, Bryant Chow (speaker slides here)

Recordings: Day 1, Day 2, Day 3

Participants, please help us by doing the short post-workshop surveys for Day 1, Day 2, and Day 3.

What will users experience in the workshop?

lectures (Jeroen Tromp, Daniel Peter, Qinya Liu, Bryant Chow) on the basics of seismic wave propagation, seismic imaging, and the software we will use
running open-source software from inside a user-downloaded software container (via docker)
small-scale computer simulations on the multiple cores of a user's machine (MPI)
iterative seismic imaging examples in 2D ("full waveform inversion" or "adjoint tomography")
demonstration of extension to 3D seismic imaging
introduction to SPECFEM3D, including running the mesher and solver (MPI)
research-ready environment for small-scale 2D jobs

What will users NOT experience in the workshop?

installation and compilation of different codes
large-scale computer simulations (2D or 3D) on high-performance computing clusters (or in the cloud)
interfacing SPECFEM3D with source estimation codes (like MTUQ)
meshing their own complex 2D and 3D seismic velocity models
configuring and installing SPECFEM3D on their own HPC cluster
3D seismic imaging examples
SPECFEM3D_GLOBE
research-ready environment for large-scale 2D and 3D jobs
