Changes that are not backward compatible

$CLAW/amrclaw/src/2d/amr_module.f90 has changed, so do a make new in any AMRClaw or GeoClaw application directories.

General changes

A gpu branch has been added to many git repositories, and checking this out gives a GPU version of two-dimensional AmrClaw and GeoClaw, as described at Using the GPU version of Clawpack. This version does not have equivalent capabilities to v5.6.1, however, and is not included as part of the tar file for this release.

Changes to classic

None.

Changes to visclaw

See visclaw diffs

Changes to riemann

  • 1D MHD solver added.

See riemann diffs

Changes to amrclaw

  • Improvements in how timing of code is done, in particular using integer(kind=8) variables for better computation of wall time.

  • Improve handling of AdjointData file references.

See amrclaw diffs

Changes to geoclaw

  • Some fixes to checkpoint and restart files

  • Several changes to storm surge codes, including handling more forms of storm input data.

  • Improvements in how timing of code is done, in particular using integer(kind=8) variables for better computation of wall time.

  • Faster version of filpatch improves regridding performance substantially for some applications by re-using topo values rather than recomputing them.

  • If some topo values are missing replace by value that makes this clearer by default, or allow the user to set an appropriate topo_missing value.

  • New geoclaw/examples/tsunami/bowl-slosh-netcdf added to illustrate using netCDF topofiles.
