Application Development [Top]
ALICE - The ALICE (Advanced Large-Scale Integrated Computational Environment) MEMORY "SNOOPER" (AMS) is an application programming interface (API) designed to help in writing computational steering, monitoring and debugging tools. The AMS API is a client/server, multithreaded API. It also supports parallel applications using MPI.
FCAT - FCAT (FORTRAN Coverage Analysis Tool) is used for the Coverage Analysis of FORTRAN codes. 
  • finding out "cold-spot" in Fortran codes (the part of the codes that are never executed), and flags these parts line-by-line.
  • finding out "hot-spot" in Fortran codes (the part of the codes that are most frequently executed), and gives a line by line profile. 
FiWizard - The Fortran interface wizard automatically generates code for creating a Fortran DLL and interface code for using the DLL from Borland Delphi. A sample delphi project can also be generated. 
F2KCLI - an implementation of the proposed Fortran 200x command line interface from Interactive Software Services.  It is intended to provide an immediate and near-universal solution to the Fortran command line access problem.  At the same time it provides upwards compatibility with future standards. 
FMKMF - A macro (UNIX "shell script") to construct a make file for a Fortran 90 program that uses modules. 
FORTRAN 78 (?) Test Suite - Software Diagnostics and Conformance Testing Division, National Institute of Standards and Technology (WARNING:  1.5MB GZIP compressed, 9MB uncompressed)
FPX3 - Fortran Preprocessor with embedded Perl which can be used to simplify Fortran source code development with an integrated set of macros, directives and embedded Perl.  Most common tasks can be done without Perl background using the documented examples.  For sophisticated source code transformations Perls broad functionality can be used.  There is support for Fortran context sensitive macros and local name spaces.  Structural and dependency information for subsequent tools can be generated.
FRUIT - FRUIT  is a unit testing utility written for Fortran.  The project started in 2004 when I did development in Fortran.  Westinghouse donated this project to open source community. 

The main goals of FRUIT are: 1) have Fortran code unit tested, 2) make TDD possible in Fortran. 

Features of FRUIT include: 

  • Pure FORTRAN, so all modules and subroutines can be tested.  Core modules are just 2 FORTRAN files.
  • Follows XUnit guidelines, it handles setup/teardown, test_xxx .
  • Enables you to do Test Driven Development, and Behavior Driven Development in FORTRAN.
The significant improvements in FRUIT 2.1 (as of 1/27/08): 
  • The user only has to maintain module_test.f90.  It is one module.  The drivers are generated automatically by ruby script.
  • Created one complete sample of how to use the code.
  • Enhanced the report, and usability.
  • Switched from make to rake.  Now I can handle a lot of automatically generated code stuff.  This project has a complete build system.
  • Added features such as rSpec. So that you can really do TDD, and BDD, to have one executable requirement.  This is pretty powerful, if you put that into your process.  Then your requirement document, test plan, test report can be automatically generated.
Pure Fortran Example:  "Add Fruit to Your Diet in 3 Minutes - TDD in Fortran" (http://fortranxunit.wiki.sourceforge.net/FruitExample)

After downloading, the sample directory shows major features.  Additional samples are in work at: http://fortranxunit.wiki.sourceforge.net/ .  Contributors to this project are welcome. 

Enjoy your fruit!, Regards, Andrew Chen

The resulting trace data are replayed pictorially to provide a dynamic depiction of the behavior of the parallel program, as well as graphical summaries of its overall performance.  The same performance data can be viewed from many different visual perspectives to gain insights that might be missed by any single view. The necessary execution trace data are produced by MPICL, developed by Pat Worley of Oak Ridge National Laboratory, which uses the profiling interface of MPI to provide timestamped records of MPI events.

PHYSUNITS - This software is an outgrowth of a paper that we recently published in the journal  Software - Practice and Experience.  The subject is automated computation and consistency checking of physical dimensions and units in scientific programs.  A  ready-to-use prototype Fortran-90 module that fully implements the proposed system is available below.  Legacy Fortran-77 code can be easily converted to utilize the system with only minor recoding.  The module is most likely to be useful in scientific programs, such as geophysical models and satellite retrieval algorithms, that are forced to deal with heterogeneous systems of units and/or complex formulas involving physically dimensioned constants and variables. For example, some old canned cloud physics subroutines in our own software library expect water densities in g/cm3; others expect kg/m3 . Many similar examples exist for drop sizes, fall speeds, scattering cross-sections, extinction coefficients, and the like.
