Seismic Toolbox Release Notes

v4.1.0

Added:

  • Added BSTimer package.
  • Do a full BSTimer library integration with the Seismic Toolbox, updating the timing utilities to be fully dependent on BSTimer and remove old library dependency.
  • Added new random boundary approach.
  • Added support to staggered first order computation kernel for DPC++.
  • Added support to staggered first order CPML boundary manager for DPC++.
  • Added support to staggered first order computation kernel for OpenMP Offload.
  • Added support to second order and staggered first order CPML boundary manager for OpenMP Offload.
  • Added backend unification module for easing development process for different backend.
  • Updated BS IO submodule's HEAD, and change codebase accordingly.
  • Added BSBase package.
  • Completely deprecated Helpers submodule.
  • Added new Random Boundaries approach to all three technologies (OpenMP, OpenMP Offload and OneAPI).

v4.0.0

Added:

  • Added Two propagation features to OneAPI.
  • Added CFL condition to OpenMP Offload.
  • Added Two propagation features to OpenMP Offload.
  • Added support to none, sponge, and second order CPML boundary manager for OpenMP Offload.
  • Added ZFP compression feature to OpenMP Offload and OneAPI.

v3.0.2

Added:

  • Do a full I/O (Thoth) library integration with the Seismic Toolbox, updating the read/write utilities to be fully dependent on Thoth and remove old library dependency.
  • Update modelling to depend on the I/O (Thoth) library as well.
  • Added source maximum frequency resampling and user specified maximum frequency amplitude percentage.
  • Added dip angle applying before stacking in correlation kernel.
  • Added boundary managers tests:
    • None boundary manager
    • Random boundary manager
    • Sponge boundary manager
    • CPML boundary manager

v3.0.1

Fixed:
