Version 0.9 -- February 2016

LA-CC-12-021

https://github.com/lanl/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:

0.9, February 2016:

     Added leblancx64 problem.  Added energy check diagnostic

     for verifying large problems.

0.8, November 2015:

     Added multi-node test problems.  Added information for

     APEX benchmark testing.

0.7, February 2015:

     Further optimizations for MPI+OpenMP.

0.6, February 2014:

     First MPI version.  MPI capability is working and mostly

     optimized; MPI+OpenMP is working but needs optimization.

     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.

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.
