This is the first in a quarterly series of columns about netlib.

Never heard of it? Then read: Jack J. Dongarra and Eric Grosse,

``Distribution of mathematical software via electronic mail'',

Communications of the ACM (1987) 30, 403-407.

Or, if that's too much trouble, just send e-mail containing the line

``help'' to the Internet address netlib@research.att.com or uucp

address uunet!research!netlib. A few minutes later, assuming you

have speedy mail connections, you will receive information on how to

use netlib and an overview of the many mathematical software libraries

and databases in the collection.

Each column in this series will start with a background discussion of

how netlib is run, applications in other fields, security horror

stories, and so on. The second half of column will briefly describe

recent additions to the collection and important updates of old codes.

If there are specific topics you would like to see addressed in future

issues, let me know.

Strictly speaking, this column only applies to the netlib running at

Bell Labs in New Jersey. If you're accessing the copy at Oak Ridge, or

Oslo, or Wollongong, or perhaps elsewhere, then the files should either

be there already or will show up shortly when our semi-automatic

procedures resynchronize the collections.

This first column provides a nice opportunity to publicly thank our

sponsors. The U.S. National Science Foundation provided an early grant

to help get us started, and implicitly helps by funding the national

network. AT&T has donated machine resources, communication

facilities, and my time. Sequent generously loaned a machine, operated

by Oak Ridge National Laboratory, to support netlib. The Norwegian

government, through a grant to Petter Bjorstad, purchased a machine

to provide service to Europe. The ACM agreed to redistribution of its

Collected Algorithms, and Algorithms Editor R. J. Renka arranged for

prompt updates. SIAM contributed its membership database. To all

these groups and the many others who contribute, the community owes

thanks.

Naturally, this thanks should not be expressed in the form of a lawsuit

if you're unhappy with some piece of software. None of the

organizations had anything to do with the content, and even the editors

make no claims about the suitability of the software for any purpose.

That's the meaning of the disclaimer ``Anything free comes with no

guarantee.''

On the other hand, don't be completely frightened off by this warning.

The mathematical algorithms in netlib include some of the most

sophisticated and robust methods to be found anywhere. Just remember

that a healthy skepticism is appropriate when you get software from any

source.

*** Recent additions ***

PLTMG edition 6.0 is a package written by Randy Bank, UCSD, for

solving elliptic partial differential equations in general regions of

the plane. It features adaptive local mesh refinement, multigrid

iteration, and a pseudo-arclength continuation option for parameter

dependencies. The package includes an initial mesh generator and

several graphics packages. Full documentation can be obtained in the

PLTMG User's Guide, newly published in the SIAM Frontiers in Applied

Mathematics series.

This library consists of a number of Fortran files and a few C files,

most of which (aside from the graphics) are machine independent. Since

the package is rather large, it has been made available via ftp

research.att.com, for those who have Internet access. Log in as

anonymous and cd dist/pltmg. You must uncompress the .Z files

once you have a copy of them. Someday we plan to make all of netlib

available by ftp.

Version 2.1 of the dhrystone benchmarks in Ada, C, and Pascal is

a new release from Reinhold Weicker, replacing the earlier (1984)

version.

Source code and runtime libraries for the Fortran-to-C converter

are now available, courtesy of Stu Feldman of Bellcore, David Gay and

Norm Schryer of AT&T Bell Labs, and Mark Maimone of CMU. Since last

fall, you have been able to exercise f2c by sending netlib a message

whose first line is execute f2c and whose remaining lines are the

Fortran 77 source that you wish to have converted. Return mail brings

you the resulting C, with f2c's error messages. During the initial

experimental period, incoming Fortran is being saved in a file. Don't

send any secrets!

The na-digest directory is an archive of the NA-NET Digest, an

electronic mailing moderated by Gene Golub and Cleve Moler. File names

are of the form v87n1. (Starting with 1990, names are of the form

v90n01, to simplify sorting.)

VFFTPK Version 2.1, May 1990 is a vectorized package of Fortran

subprograms for the fast Fourier transform of real sequences, by Roland

Sweet and Linda Lindgren, NIST Boulder, and Ronald Boisvert, NIST

Maryland. It is a vectorization (for transforming multiple sequences)

of the package FFTPACK (Version 3, June 1979) written by Paul N.

Swarztrauber of NCAR.

This was written 27 July 1990 and is intended to be co-published

in the electronic NA-NET Digest, the SIAM News, and the SIGNUM

Newsletter. The author is in the Computing Science Research Center at

AT&T Bell Laboratories, Murray Hill NJ 07974, USA. He can be reached

by email at ehg@research.att.com.
