CPSeis is an open source seismic processing system from ConocoPhillips. It contains a GUI, job builder, and workstation run-time engine for non-parallel jobs, and we're close to re-testing the parallel cluster version.
See http://sourceforge.net/projects/cpseis for more details.Successfully built on 32 and 64 bit linux. You must build fftw 2.1.5 and mpich/mpich2 with shared libraries for everything to work. (see the installation script in .../cpseis/scripts/build_cpseis).
