CHANGES: Underworld2

Release 2.9.4 [2020-03-26]

Changes:

  • Updating Dockerfile to include UWGeodynamics-2.9.4.

Release 2.9.3 [2020-03-09]

Changes:

  • Update citation information in README.md.

Release 2.9.2 [2020-02-26]

Changes:

  • Update Zenodo title.

Release 2.9.1 [2020-02-18]

Enhancements:

  • Update base docker image & implement permission fixes.
  • Other docker tweaks and corrections.
  • Fixes for image tests

Release 2.9.0 [2020-01-20]

New:

  • Experimental pip install functionality.
  • Installation instructions for NCI Gadi.
  • Singularity usage instruction Pawsey Magnus.
  • UW_VIS_PORT environment variable flag added to set vis port.

Docker:

  • Images now use Python 3.7 (previously Python 3.5).
  • Multi-stage builds used improved image creation.
  • Images minimised with unnecessary items removed.
  • XVFB no longer required for image generation within container.

API changes:

  • glucifer module moved inside underworld and renamed visualisation. Access as import underworld.visualisation
  • GLUCIFER_USE_XVFB -> UW_USE_XVFB.
  • --prefix=/SOME/DIR now installs to /SOME/DIR/underworld
  • test_basic.py no longer sets PYTHONPATH
  • underworld.matplotlib_inline() -> underworld.utils.matplotlib_inline().

Enhancements:

  • By default, UW was creating significant filesystem chatter in generating debug messages for functions. This has been significantly reduced through judicious usage of Python inspection tool. Also, as default, only root proc now generates messages. Users can set the UW_WORLD_FUNC_MESSAGES (export UW_WORLD_FUNC_MESSAGES=1) environment variable to have all procs report, or can set UW_NO_FUNC_MESSAGES (export UW_NO_FUNC_MESSAGES=1) to disable these messages altogether for minimal filesystem noise.
  • Complete long type SwarmVariable implementation. Specifically, evaluate() methods now work for this data type.

Deprecations:

  • Raijin install instructions removed.
