| 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. |
