The 3D free surface inverse scattering series (ISS) multiple removal
code was written by Sam Kaplan in 2006.  Before the code could be tested
or documented, Sam Kaplan began his Ph.D. studies at the University of
Alberta.The code was subsequently tested and debugged by Haiyan Zhang
and Simon Shaw (ConocoPhillips), Sam Kaplan (University of Alberta), and
Zhiqiang Wang (M-OSRP) and with  Kris Innanen, the M-OSRPcontact/connection.  

The linked-to packages represent a current (summer,2009) snap-shot of the code-base.  The  
code is undocumented, but is similar to the 2D free surface ISS  
multiple removal code, and whose 
documentation can be found on this web-page.  Hence, an understanding of
the 3D code should follow from an understanding of the 2D code.  One
notable exception is the slac library which now uses the GNU auto-tools
(http://www.gnu.org/software/autoconf/) for installation.

 

Forward Modeling code:

For the M-OSRP internal multiple attenuation project, we test the code using synthetic data sets. To that end, we have finite difference code which produces data for an acoustic, isotropic and non-viscous 2D model, and a line source.

Older Version:

download code: (fd_acoustic.tar.gz , fd_demos.tar.gz , slac.tar.gz )
access documentation

The documentation (linked to above) describes how to get the code from CVS. This is something that we are planning for the future. For now, please disregard this section of the documentation, and retrieve the code by simply clicking on the above links. You will need to download all three of the codes (fd_acoustic.tar.gz, slac.tar.gz and fd_demos.tar.gz).

This version of the IMA code is written for and tested with the IBM Blue Gene architecture. However, it likely also applicable to any large scale distributed computing system, and we encourage its use, as such.

The documentation (linked to above) describes how to get the code from CVS. This is something that we are planning for the future. For now, please disregard this section of the documentation, and retrieve the code by simply clicking on the above links. You will need to download both codes ("impred_blade.tar.gz" and "slac.tar.gz").
