PENNANT Description:

PENNANT is an unstructured mesh physics mini-app designed for advanced
architecture research.  It contains mesh data structures and a few
physics algorithms adapted from the LANL rad-hydro code FLAG, and gives
a sample of the typical memory access patterns of FLAG.

Further documentation can be found in the 'doc' directory of the
PENNANT distribution.


Version Log:

0.6, February 2014:
     Replaced GMV mesh reader with internal mesh generators.
     Added QCS velocity difference routine to reflect a recent
     bugfix in FLAG.  Increased size of big test problems.
     [ Master branch contained this change but CUDA branch does not:
     First MPI version.  MPI capability is working and mostly
     optimized; MPI+OpenMP is working but needs optimization. ]

0.5, May 2013:
     Further optimizations.

0.4, January 2013:
     First open-source release.  Fixed a bug in QCS and added some
     optimizations.  Added Sedov and Leblanc test problems, and some
     new input keywords to support them.

0.3, July 2012:
     Added OpenMP pragmas and point chunk processing.  Modified physics
     state arrays to be flat arrays instead of STL vectors.

0.2, June 2012:
     Added side chunk processing.  Miscellaneous minor cleanup.

0.1, March 2012:
     Initial release, internal LANL only.
