Fortran 90 is, with very few exceptions, a superset of Fortran 77. The FAQ of the Usenet group Comp.lang.fortran deals with both standards, and may be obtained, like any FAQ, via anonymous ftp from rtfm.mit.edu, directory /pub/usenet/comp.lang.fortran.

A specific Fortran 90 FAQ by Mike Metcalf may be reached at the Fortran Market.

The present document is an attempt to supplement these FAQs with some more links to Fortran 90/95 information.

Anyone interested is also invited to join the mailbase list comp-fortran-90, by sending an e-mail message to mailbase@mailbase.ac.uk, containing the only line:

The main extensions of Fortran 90 over Fortran 77 are:

• array notation (for instance, X(1:N)=R(1:N)*COS(A(1:N)))
• dynamic memory allocation (ALLOCATE, DEALLOCATE, ...)
• derived types and operator overloading
• better declarations, and prototyping possible
• MODULES, allowing users to create ``storage pools'', or to define environment
• more of modern control structures (SELECT CASE, EXIT, ...)
• more of useful intrinsics (date, precision, arrays, ...)
• free format source code form

``Pure'' Fortran 77 is F90 compatible. Yet, it is better to convert it to a ``mixed'' format, acceptable both as free and fixed source form Fortran 90, which only requires replacing C by ! as the comment character, to use & as the continuation line character, and to append it to the continued line, to remove blanks embedded inside constants or identifiers, and to check some intrinsics usage. Most of this can be done automatically.

Fortran 90 allows the Fortran 77 programmer to write code faster, to make it more legible, and to avoid many bugs. For a newcomer to programming, it is an opportunity to learn a modern language, with most recommended features, and yet to be in line with scientific and industrial engineering communities where Fortran is and is going to remain for a good while THE favourite language.

Fortran 95 is a minor revision of Fortran 90. The 3 main extensions with respect to that previous version are:

• FORALL statement and construct
• PURE and ELEMENTAL procedures
• Structure and pointer default initialization

Standards

ISO/IEC 1539:1997

International Standard

Information technology - Programming langages - Fortran Somewhat expensive (CHF 210 ~ US$ 140 !) for instance, at ISO. Surprisingly enough, the identical, save for foreword and acknowledgements, ANSI standard X3.198-1992 is even more expensive. Walter S. Brainerd, Unicomp., offers:

- for 125 US$, an electronic ascii monouser version,

- for 125 + 10n US$, an electronic PostScript version, and the right to make n paper copies,

- or for 1000 US$, an electronic ditroff monouser version.

An interesting article by John K. Prentice appeared in the May/June 93 issue of Fortran Journal. He also gave a new one in the Nov/Dec 94 issue.

I made some tests myself with LAPACK, and got a ratio of 10 between Sun f77 and Nag f90 2.0 when no source change was performed. With an aggressive rewriting, especially using array instructions and intrinsics, the ratio gets down to 2, which is also that of a f77 [sd]axpy to a C one.

On actual applications, this ratio seems to be much closer to 1, and even sometimes in favor of Fortran 90. On Sept. 7th, 1993, John wrote "I think there is in fact beginning to be a quite large body of evidence to suggest that most of the efficiency fears about F90 are unfounded."

For Nag f90 on workstations, the effect of the underlying C compiler (gcc, vendor, etc...) seems very limited (less than 4%).

With more recent F90 compilers, performance seems at least as good and often better than with the corresponding F77 compiler, for old F77 code. For instance, Lahey reports improvement from 8.5 to 14.1 Mflops with linpack on a pentium between EM/32 and their F90 compiler.

Fortner (LS Fortran) has exited the Fortran business on Mac (to concentrate on visualization tools). Per agreement with Fortner, Absoft is offering migration path from LS Fortran -> Absoft Pro Fortran. See: http://www.absoft.com/fortner.letter.html or contact dave@fortner.com for details

Absoft and Intel have signed deal to evolve Absoft Fortran toolsets for IA/NT.

Work did not stop with the publication of the Fortran 90 standard. A new release is scheduled for 1996 (called 95), mainly devoted to clarifications, corrections and interpretations. It is currently being circulated as a draft for comments. A more important revision is scheduled for 2000 (or 2001 ? called F2k though C.Burley's F00 is a pleasant alternative). Some interim features are to be processed as "technical reports" and incorporated in the next major upgrade, now known as "Fortran 2000" and planned for release around the year 2000. The features for which interim technical reports have been proposed are the following: Floating-point exception handling Interoperability with C Parammeterized derived types and allocatable components However, the last of these lacks support in some quarters.

The ISO working group devoted to the evolution of Fortran is WG5. Inputs are received from the National bodies (X3J3 in the USA). Documents related to the work of X3J3 can be found via anonymous ftp on ftp.ncsa.uiuc.edu, directory x3j3.

High Performance Fortran (HPF) is a language for programming massively parallel architectures. It lets the user insert directives for code and data distribution among the processors in the (Fortran 90) code. It is now available in version 2.0.

Parallel Virtual Machine consists of a library and a run-time environment which allow the distribution of a program over a network of (even heterogeneous) computers. It works with Fortran 77, C and to some extent Fortran 90. One can refer to the article by Y-H de Roeck and R-E Plessix, and a set of example wrapper routines for the PVM calls is available as:

There is a usenet comp.parallel.pvm group, and the FAQ for it can be found via anonymous ftp on:

MPI (Message Passing Interface) is the standard for multicomputer and cluster message passing introduced by the Message Passing Interface Forum in April 1994.

Co-array Fortran is a simple way of parallel programming in Fortran, that is getting very popular.
