The PENNANT Mini-App Charles R. Ferenbaugh Los Alamos National Laboratory email@example.com Version 0.9 -- February 2016 LA-CC-12-021 https://github.com/losalamos/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.
