Hermes Utility Libraries and Tools

This software is a set of utility libraries and tools developed in support of multiple scientific simulation projects. These libraries provide many general-purpose capabilities, such as a compact, extensible, machine-independent binary file format for various forms of scientific data, a Fortran-callable command parser that supports symbolic variables, looping, and conditional constructs, a Fortran-callable interface to ITT Corporation's callable IDL graphics and data analysis, a multi-block, 2D electrostatic solver, a machine-independent Fortran interface to standard system services, and various Fortran-callable dynamic memory services. In some cases, C interfaces are also provided. In addition, some tools that use these various libraries are available. A brief description of each library/tool follows: PFF library - PFF is a compact, extensible, machine-independent binary file format for various forms of scientific data. Two libraries are provided: one designed to be called from Fortran 77, and the other designed to be called from C or C++. Dataset types for several varieties of scientific data are built into the library, and new dataset types can be added. The libraries provide support for reading/writing these datasets from/to PFF files, as well as functionality for interactive processing of PFF files and the data they contain. Tools for manipulating, converting, and comparing PFF data are also available.
