Subject: Has Moved

The machine running netlib has been moved from Argonne to Oak Ridge.
We hope the move didn't cause any problems, hopefully you were unaware
of the relocation. During the move, mail to the old Argonne address was automatically forwarded to Bell Labs.

You can still send mail to Bell Labs by sending requests directly to
The contents of the collection at Oak Ridge and Bell Labs are
nearly identical. Interesting exceptions are the approximation catalog
and Fortran-to-C converter at, some software tools and
reports see the index from tools (mail to,

The address for netlib at Oak Ridge National Laboratory is Mail to the old address,, will
continue to work for a month or so by automatically forwarding mail
to Oak Ridge.

Subject: LINPACK Benchmark Report

I have just made a major revision to the ``LINPACK Benchmark Report''.
If anyone would like a hardcopy of the report send me your address
and it will be mailed out. The report is also available from netlib in
post-script form. To get a copy via email, send mail to
The mail message should say:

send performance from benchmark


[Editor's warning: The postscript file for Dongarra's report is HUGE.
If you asked for a copy of an earlier version from netlib, you would get
almost 2 megabytes of mail, split into 19 mail messages. I don't
know how big today's version is, but unless you really want the postscript,
you are probably better off sending Jack your postal address and
waiting for the paper copy. --Cleve ]

Subject: Kahan Named Winner of Turing Award

Prof. W. Kahan of the University of California at Berkeley is the winner
of the 1989 Turing Award. It is being awarded for his contributions in
computer architecture and numerical analysis, in particular for his work
on the IEEE floating point arithmetic standards 754 and 854. These
standards have been very widely adopted by the computer industry.
Prof. Kahan is cited as uniquely having used numerical analysis to
influence computer architecture. Indeed, anyone who uses a workstation,
PC, or HP calculator to do floating point computation has likely benefited
(perhaps unknowingly) from his ideas.

His work on computer arithmetic grew out of many battles to get the right
answer despite inaccurate computer arithmetic, inconsistent compilers, and
unresponsive operating systems. For example, on some early calculators the
expression "arcsin(sin(x))" would yield an "argument out of range" message
for some arguments x near 90 degrees. The reason was that for these
arguments the computed value of the sine was greater than 1. This seems merely
amusing until one has taught freshmen who write sines exceeding 1 as test
answers. To see that the problem extends beyond cheap calculators, the absence
of a guard digit on Cray systems has delayed production of a portable divide
and conquer algorithm for the symmetric tridiagonal eigenproblem for many
months, whereas it is clear how to write such a code for machines with more
careful rounding.

Many of these problems are easily fixed, or could have been easily avoided had
the designers known what arithmetic properties were important. Indeed, it is
the fact that so many numerical analysts have had to waste mental energy trying
to write reliable code despite these problems that has motivated Prof. Kahan
to work on well designed arithmetic systems.

Prof. Kahan's contributions also include numerical linear algebra and error
analysis. For example, the kernel of the standard algorithm for the singular
value decomposition is based on a joint paper with Gene Golub. He has also
been a vocal critic of various schemes which purport to automatically protect
users from roundoff and over/underflow errors.

Many of Prof. Kahan's ideas have been reported by his colleagues (with
appropriate credit of course) rather than in his own formal publications.
A notable collection appears in "The Symmetric Eigenproblem" by Beresford
Parlett. Of course, one can consider him a principal coauthor for every
Intel 8087, Motorola 68881, or other similar floating point chip produced.
Prof. Kahan's point of view has long been that most numerical analysis
papers are destined to be read by a few colleagues at most, and with
correspondingly narrow influence. To truly improve the way people compute,
the ideas must be incorporated in easily available hardware or software
packages which can be used without needing to read the corresponding papers.
Two examples of such packaging are the "solve f(x)=0" and "integrate f(x)"
keys on HP calculators which he designed. Prof. Kahan has pursued this
approach consistently and successfully for a long time.

The Turing Award ceremony is February 20, 1990, during the ACM Computer
Science Conference in Washington, D. C.

Subject: CRAYFISHPAK Available


CRAYFISHPAK(TM) is a package of FORTRAN 77 subroutines for solving second-
order finite difference approximations to two- and three-dimensional
Helmholtz equations in cartesian, cylindrical, and spherical coordinates
with any combination of periodic or specifications of the solution or its
normal derivative on the boundaries of a regular domain. More general
separable elliptic partial differential equations may be solved by directly
interfacing to one of a suite of seven special block tridiagonal linear
system solvers. Highly vectorized Fast Fourier Transform and cyclic
reduction algorithms are used to solve the linear systems of equations.

Following the style and spirit of the well-known and heavily-used FISHPAK
package, the sixteen CRAYFISHPAK drivers use finite difference approx-
imations on standard or staggered grids to convert a straight-forward
description of the equation, domain, and boundary conditions into a linear
system of equations and call an appropriate solver routine that computes the
solution. All singular problems and coordinate singularities are treated
automatically. Extensive error checking of input parameters is performed to
detect improperly specified problems. Useful de-bugging facilities decrease
the time required to successfully interface to any routine.

Designed for time-dependent (e.g., fluid-dynamics) applications, all
routines have separate initialization subroutines that completely define the
linear operator and perform significant pre-processing which speeds the
solution of a given problem. In this way repeated solutions corresponding
to different data are obtained much faster. Timing studies demonstrate that
CRAYFISHPAK routines are well over an order of magnitude faster than compar-
able FISHPAK routines. For example, on a single-processor Cray X-MP the
solution of Poisson's equation in cartesian coordinates on a 64x64x64 grid
executes in 108 milliseconds (18 times faster than FISHPAK routine HW3CRT)
at an average speed of 100 megaflops. For time-dependent applications this
new package has the potential to significantly reduce computer costs.

CRAYFISHPAK is available in Fortran source form and is licensed for use on a
single machine. It consists of 18,500 lines of source code. On-line
documentation, consisting of 6,500 lines, is contained in 23 ASCII files.
Each file describes the input/output parameters and other pertinent
information for one user-accessible routine. There is a 100-page User's
Guide that provides general information about the entire package and
descriptions of the finite difference approximations used in each driver.
