Programming Guidelines for PARAMESH Software Development (NOTE: This document is heavily based upon the Introduction This document describes the programming guidelines to be used by software developers wishing to contribute software to the PARAMESH, parallel, adaptive mesh refinement software.?? We welcome people to contribute software and/or bug fixes to the PARAMESH AMR software.?? Software to be added to PARAMESH can come in 2 forms: Improvements to the basic PARAMESH kernal software found in the mpi_source, source and hearders directories. Software the addes additional functionality to PARAMESH.? This type of software should be added as separate entities within the utilities directory. Complete applications should not be added as part of PARAMESH.?? PARAMESH is only meant to be a tool which supports parallel adaptive mesh applications and any software which supports this goal will be considered for acceptance into PARAMESH.? For instance, a solver for the poisson equation that works with PARAMESH would be acceptable, but an application that solves the equation of gas dynamics would not.The PARAMESH software is slowly being evolved to be consistent with this document.? Any new software which is contributed should follow these guidlines.? If not, it will be rejected.? This document deals mainly with Fortran 90, since most new PARAMESH software will probably be written in that language. [Throughout this document, the term Fortran should be understood to mean Fortran 90.]? Since we expect C and C++ also to be used, a separate document dealing with them will be developed in the future. ? In the meantime, this document can serve as a general guideline for developing code to be used with PARAMESH in those programming languages.The guidlines in this document should be adhered to by ANY software which will be released as part of the PARAMESH package ofsource code.? This includes software utilities (stored in the paramesh/utilities directory) which add functionali
