Ferenbaugh\nLos Alamos National Laboratory\ncferenba@lanl.gov\n\nVersion 0.9 -- February 2016\nLA-CC-12-021\nhttps://github.com/lanl/PENNANT\n\n\nDescription:\n\nPENNANT is an unstructured mesh physics mini-app designed for advanced\narchitecture research.  It contains mesh data structures and a few\nphysics algorithms adapted from the LANL rad-hydro code FLAG, and gives\na sample of the typical memory access patterns of FLAG.\n\nFurther documentation can be found in the 'doc' directory of the\nPENNANT distribution.\n\n\nVersion Log:\n\n0.9, February 2016:\n     Added leblancx64 problem.  Added energy check diagnostic\n     for verifying large problems.\n\n0.8, November 2015:\n     Added multi-node test problems.  Added information for\n     APEX benchmark testing.\n\n0.7, February 2015:\n     Further optimizations for MPI+OpenMP.\n\n0.6, February 2014:\n     First MPI version.  MPI capability is working and mostly\n     optimized; MPI+OpenMP is working but needs optimization.\n     Replaced GMV mesh reader with internal mesh generators.\n     Added QCS velocity difference routine to reflect a recent\n     bugfix in FLAG.  Increased size of big test problems.\n\n0.5, May 2013:\n     Further optimizations.\n\n0.4, January 2013:\n     First open-source release.  Fixed a bug in QCS and added some\n     optimizations.  Added Sedov and Leblanc test problems, and some\n     new input keywords to support them.\n\n0.3, July 2012:\n     Added OpenMP pragmas and point chunk processing.  Modified physics\n     state arrays to be flat arrays instead of STL vectors.\n\n0.2, June 2012:\n     Added side chunk processing.  Miscellaneous minor cleanup.\n\n0.1, March 2012:\n     Initial release, internal LANL only.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flanl%2Fpennant","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Flanl%2Fpennant","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Flanl%2Fpennant/lists"}
