HPC geophysical simulation test suite

HPC geophysical simulation test suite

The HPC geophysical simulation test suite (HPC4E Seismic Test Suite) provides both developers and users of HPC geophysical imaging tools with a set of tests that is scalable in size, easy to set up and equally usable with any kind of 3D seismic modelling algorithm. This includes elastic and acoustic models, with and without topography. The Test Suite features:

  • 4 models and a series of tests of different size and physical simplifications (labeled AF, AT, EF and ET);
  • 2 wavelets: with cutoff frequency at 20 Hz and 50 Hz respectively;
  • 2 shot layouts: unit (1 single shot) or survey (1681 shots).

These features combine to allow up to 16 different tests of various sizes and complexities. A script is provided that generates 3D gridded volumes and 2D gridded layer surfaces for any desired spacing, so that the resolution requirements of any modelling code can be met. The output makes it very easy to run the tests with grid-based methods (e.g. finite differences), unstructured mesh-based methods (discontinuous Galerkin or (spectral) finite elements) or even boundary element methods.

In the zip file below you will find a description document and a README file, the scripts and data that generate any of the models of the Test Suite, as well as wavelets and a description of each model’s physical properties.
