These sites all relate to High Performance Computing, parallel computing, Fortran 95, or numerical computing. This list is in no way intended to be exhaustive, but merely to provide further sites you may find useful.

Fortran Standards Organizations, Etc.

The Official Home of the ISO Fortran Standard, here is a good source of information: corrigendum, status of future standards, and how to obtain official documents. ISO/IECTJTC1/SC22/WG5 (Fortran)
NAG, Ltd. hosts the home of WG5, the ISO Working Group responsible for Fortran sc22wg5
J3 is the technical committee who write the Fortran Standard. Their current effort is directed towards Fortran 2008, due to be published in 2010. To see the meeting schedule and working papers, including the current draft of the new Fortran standard, go to the J3 Fortran Standards Committee.
Coarray Fortran is a minimalist's extension to Fortran 95 to produce a parallel programming language capable of producing efficient code on SMP and DMP platforms using an SPMD execution model. The definitive paper by Robert W. Numrich and John Reid may be found at Rutherford Appleton Labs. Co-array Fortran now has a home on the Web. Find out more (including links to a subset Co-array Fortran to OpenMP converter) by visiting Co-array Fortran.
The High Performance Fortran Forum is the force behind the HPF standard of Data Parallel computing using directives imbedded in the source code. Some HPF constructs, such as the FORALL construct, appeared in standard Fortran 95. High Performance Fortran Forum Home Page
The OpenMP Consortium define a set of directives for parallelizing Fortran programs which is supported by several vendors. For more information, visit OpenMP.

Fortran Source Code

Netlib has available for free download a wide variety of software for use in numerical programs. There is also a wide variety of parallel processing software. Visitors may search or browse the site. Netlib
This site is the High Performance section of Netlib. National HPCC Software Exchange
NIST maintains the Guide to Available Mathematical Software here. Guide to Available Mathematical Software
This site has information on the Numerical Recipes textbooks and source code on floppy disk and CD. Numerical Recipes Home Page Not everyone is happy with the treatments provided by Numerical Recipes, for an alternative view, see this site by Van Snyder
Michel Olagnon has some useful Fortran utilities here. Moware
Michael Metcalf has a useful utility for converting fixed format source code to free format source code. Convert
Alan Miller has a fixed format to free format converter, called to_f90. It does a little more than simply convert formats. Alan Miller has much other software besides.
Herman D. (Skip) Knoble has some interesting pages, located here.
To add Roman Numerals to your Fortran application, try Jeanne T. Martin's Roman Numeral Module, this link via the Fortran Company.

Fortran (& HPF) Tutorials

Bo Einarsson has a Fortran 90 tutorial for the Fortran 77 Programmer here. Fortran 90 for the Fortran 77 Programmer
A good tutorial for those wishing to learn about Fortran 90 array syntax and HPF data distribution may be found here. EPCC: HPF Course Slides
Chuck Koelbel of CRPC at Rice University has a good HPF tutorial, including HPF 2.0. HPF Tutorial

Fortran Resources

The Fortran Company should be your starting point for Commercial Fortran inquiries. It features links to vendors, and has lists of books on Fortran (in many languages). Go to the Fortran Company.
The Fortran Library has a collection of Fortran-related information. Go to the Fortran Library.
Phillip Helbig has some pages with many useful links here, including links to source code for a Fortran 90 module implementing ISO Varying Strings. Go to Phillip Helbig's Fortran Information pages.
The Fortran Company has information about a free subset Fortran compiler, F. F also has textbooks available for it. Go to the Fortran Company
Polyhedron has a comparison of Fortran compilers for the personal computer, including benchmarks. See Polyhedron.
While it's not written in Fortran, but C, Robert Moniot's famous ftnchek program is a valuable addition to the Fortran 77 programmer's toolkit.
