Background
The mission of the Mathematical
and Computational Sciences Division (MCSD) is
To provide analytical and computational methods for solving scientific,
engineering, and information technology problems critical to American industry.
Our customers are quite broadly based, including other ITL Divisions, other
NIST Laboratories, the information technology industry in general, and
the computational science research community in particular. Within the
scope of our charter, we have set the following general goals.
-
Insure that sound mathematical methods are applied to NIST problems.
-
Improve the environment for computational science and engineering within
NIST as well as within the external community.
Since our charter is so broad, in order to succeed we must (a) take advantage
of leverage provided via close collaborations with other NIST groups, other
government agencies, and industrial organizations, (b) develop tools with
the highest potential impact, (c) provide resources, education and training,
and (d) select areas for direct external participation in domains that
are fundamental and broadly based, especially those where measurement and
standards can play a key role in the development of new products.
With these goals in mind, we have developed a technical program in three
general areas.
-
Mathematical modeling in the physical sciences and engineering, as well
as problems in information technology.
-
Development of techniques and tools for high-performance computing.
-
Development and dissemination of mathematical reference information, especially
for measurement and testing.
Most projects undertaken by the Division impact more than one of these
areas.
Division staff maintain expertise in a wide variety of mathematical
domains, including linear algebra, special functions, partial differential
equations, computational geometry, Monte Carlo methods, optimization, and
nonlinear dynamics. Application areas in which we are currently actively
involved include materials science, fluid mechanics, electromagnetics,
manufacturing engineering, wireless communications, optics, image analysis
and computer graphics.
Output of Division work includes publications in refereed journals and
conference proceedings, technical reports, lectures, short courses, software
packages, and Web services. In addition, MCSD staff members participate
in a variety of professional activities, such as refereeing manuscripts
and proposals, service on editorial boards, conference committees, and
offices in professional societies. Staff members are also active in educational
and outreach programs for mathematics students at all levels.
Overview of Technical Program
A list of activities in each of the division focus areas follow. Note
that individual projects may have complementary activities in each of these
areas. For example, the micromagnetic modeling work has led to the OOMMF
software package, as well as to a collection of standard problems used
as benchmarks by the micromagnetics community.

Technical Highlights
In this section, we highlight some of the significant accomplishments
of MCSD this past year.
Java Numerics. Java has already made a huge impact on the computing
industry. Recently there has been increased interest in the application
of Java to high performance scientific computing. This has manifested itself
in a major new activity for MCSD. At a well-attended Birds-of-a-Feather
session on Java at the SC'97 conference in San Diego it was agreed that
a formal community activity to evaluate Java for such applications should
be undertaken. The Java Grande Forum
(JGF) was the result. R. Boisvert and R. Pozo of MCSD became co-chairs
of the JGF's Numerics Working Group at the Forum's first meeting in February
1998, where they presented a paper on the design of numerical libraries
in Java. (A second working group on Concurrency and Applications, co-chaired
by D. Gannon of Indiana University and D. Caromel of INRIA, was also created.)
At that meeting, and during subsequent meetings in May and August hosted
by Sun Microsystems, the working group developed a set of requirements
for improvements to Java necessary to support high performance numerical
computing. A preliminary report
from the working group was issued in the fall and R. Boisvert presented
the results at a Java Grande Forum Panel session at SC'98 in November.
Some 20 individuals participated in the Numerics Working Group, representing
companies such as Sun, IBM, Visual Numerics, the MathWorks, and NAG, as
well as academic institutions such as the University of California at Berkeley,
Syracuse University, Loyola University of Chicago, the University of North
Carolina, and the University of Houston.
The Working Group's web
page, developed and maintained by MCSD staff, has become the premier
site for obtaining information about numerical computing in Java.
Another activity of the Numerics Working Group is the development of
proposed standard Application Programmer Interfaces (APIs) for numerical
computation in Java. To initiate this process, a team from NIST (R. Boisvert,
B. Miller, R. Pozo and K. Remington) and the MathWorks (J. Hicklin, C.
Moler and P. Webb) developed a class library for elementary numerical linear
algebra called JAMA.
A public-domain reference implementation for JAMA was released in
August. It contains facilities for elementary matrix operations, as well
as LU, Cholesky, QR, singular value and eigenvalue decompositions. More
than 750 copies of the package have been downloaded from the MCSD Web site.
Working Group participants from Visual Numerics and IBM also have proposed
APIs with reference implementations for complex arithmetic, special functions
and multidimensional arrays. APIs for interval arithmetic and multidimensional
arithmetic are currently under development by other participants.
In a related effort, R. Pozo and B. Miller developed SciMark,
a benchmark for numerical computing in Java. The benchmark, a Java applet,
is a composite of an FFT, a Monte Carlo integration, a sparse matrix multiplication,
a Gauss-Seidel iteration and a dense LU decomposition. Users can run the
benchmark on their own system and submit the results for posting on the
NIST SciMark web site.
New Competence Projects. MCSD staff members were included on
two new 5-year competence projects awarded by the NIST Director's Office
this year. A. Kearsley is one of the principal investigators for the NIST
Competence Project on Wireless Communications led by the ITL Advanced Networking
Technologies Division. His initial efforts have concentrated on applying
optimization techniques to the selection of signal sets for wireless communications.
C. Witzgall is one of the principal investigators for the NIST Competence
Project on Bayesian Statistics led by the ITL Statistical Engineering Division.
The project will develop new expertise in the application of Bayesian techniques
to statistical questions in metrology.
OpenGL Adopts NIST Bindings. The Fortran 90 bindings for the
OpenGL graphics library developed by W. Mitchell of MCSD were approved
by the OpenGL Architecture Review Board (ARB) as the official OpenGL Fortran
90 interface. The bindings were also favorably reviewed by X3J3, the U.S.
Fortran Standards Committee. OpenGL is a software interface for applications
to generate interactive 2D and 3D computer graphics. OpenGL is designed
to be independent of operating system, window system, and hardware operations,
and is supported by many vendors, with products for computing platforms
from PCs to supercomputers. The ARB is the governing board of OpenGL, and
consists of members from a variety of companies with OpenGL products including
Compaq, Evans & Sutherland, Hewlett-Packard, IBM, Intel, Intergraph,
Microsoft and Silicon Graphics.
Adoption of the OpenGL Fortran 90 bindings represents a significant
development for scientific visualization in the Fortran community. Until
now there has never been an industry standard for generating graphics from
Fortran programs; instead, only proprietary libraries that support a limited
number of systems have been available. With the new bindings, a Fortran
programmer can write standard-conforming graphics applications that will
be portable over most computing platforms.
In conjunction with this work, Mitchell has developed f90gl,
a public domain reference implementation of the Fortran 90 bindings. Since
its initial release two years ago, it has been downloaded approximately
2500 times. With the standardization of the bindings, it is anticipated
that the rate will increase, and that vendors will use f90gl as the basis
for their products. Several vendors have already expressed such interest,
including Absoft, Avid Technology, Imagine1, Lahey Computer Systems, NASoftware,
and Salford Software.
Release of New Modeling Packages. This year saw the initial release
of two major object-oriented software packages for the study of material
properties. The first, the Object-Oriented Micromagnetic Modeling Framework
(OOMMF), permits the simulation
of two-dimensional magnetic domains. Such codes are useful, for example,
for characterizing the behavior of read-write heads for magnetic storage
devices. Authored by M. Donahue and D. Porter of MCSD, OOMMF is being developed
in association with the Micromagnetic Modeling Activity Group, a working
group of industry, government and academic researchers interested in improving
the state-of-the-art in micromagnetic modeling. OOMMF is designed as a
public, highly modular, and portable code that can be used (a) to study
micromagnetic systems, (b) to benchmark other codes, and (c) to collect
community expertise via contributions of others. This work is being done
in collaboration with the NIST Materials Science and Engineering Laboratory
and the NIST Electronics and Electrical Engineering Laboratory.
This year MCSD also released the initial version of OOF,
the Object-Oriented Finite-element system for the modeling of real material
microstructures. In contrast to the large-scale regular structures that
existing commercial finite-element analysis systems address, materials
scientists need to study small-scale and highly irregular microstructures.
The interaction of pores, cracks and secondary material phases at the microscopic
level can have a profound effect on macroscopic material properties, and
materials scientists are in need of tools to study these effects. OOF,
a system developed by S. Langer of MCSD, in collaboration with colleagues
in the NIST Materials Science and Engineering Laboratory, is just such
a tool. Using OOF, a materials scientist can input a digitized micrograph
of a real material, identify the various phases, assign material properties,
and simulate material response to the application of external forces and
temperatures, all with a highly interactive graphical user interface.
Digital Library of Mathematical Functions Prototype Released. This
year MCSD staff, in collaboration with colleagues in the NIST Physics Lab,
made significant progress in getting the Digital
Library of Mathematical Functions (DLMF) project off the ground. The
DLMF is designed to be a modern online successor to the classic Handbook
of Mathematical Functions (M. Abramowitz and I. Stegun, eds., National
Bureau of Standards, AMS 55, 1964). The DLMF will include formulas suitable
for downloading into word processors and symbolic computing systems, 2D
and 3D interactive graphics, and tables, some computed on demand, supported
by extensive metadata and sophisticated search tools. The DLMF, incorporating
the many developments of the past 35 years in the understanding of functions
originally included in AMS 55, as well as information on a host of new
functions that have emerged in importance in applications. Some 60 domain
experts will be recruited to develop and verify the technical material
under the direction of NIST editors D. Lozier, F. Olver, C. Clark (PL)
and R. Boisvert, supported by 10 distinguished external associate editors.
The DLMF Web site, along with a suite of physics application modules, will
be developed by NIST staff. Significant resources and time will be required
to complete this ambitious project. We expect the DLMF to be completed
in the year 2003.
Among the significant accomplishments for this year was the development
and release of a sample Web site for the project. The site contains a chapter
on Airy functions developed by F.W.J. Olver, as well as a chapter on applications
of Airy functions developed by C.W. Clark. Interactive 3D visualizations
of the Airy functions based on VRML are also included. The associate editors
for the project were selected and a first meeting of this group has been
scheduled for early spring 1999. A proposal for the funding of external
researchers to develop material for the DLMF was submitted jointly to the
NSF Knowledge and Distributed Intelligence and Digital Libraries initiatives;
other sources for external funding are being explored. Additional internal
funding has been obtained from the MEL Systems Integration for Manufacturing
Applications (SIMA) program, the ATP Adaptive Learning Systems program,
and the TS Standard Reference Data Program.
Solution of Outstanding Dimer Covering Problem. Since 1938, physicists
and mathematicians around the world have been trying to calculate a fundamental
quantity known as the dimer constant. This year, the three-dimensional
constant was obtained using a unique computational approach by I. Beichl
of MCSD in collaboration with F. Sullivan at the IDA Center for Computing
Sciences.
In two dimensions, computing the dimer constant is equivalent to calculating
the growth rate for the number of ways to place dominoes on a checkerboard
so that each domino covers two squares, there is no overlap, and the whole
board is filled up. One wishes to find the limiting rate as the size of
the checkerboard grows large. In three dimensions, the problem changes
to the number of ways to fill a cube-checkerboard with bricks, where one
brick covers exactly two sub-cubes, one red sub-cube and one black sub-cube.
As in two dimensions, one wants the limiting rate as the cube-checkerboard
grows. Enumerating such combinations is extremely difficult: there are
more than 12 million for just the 8x8 checkerboard, for example.
Dimer constants provide essential information related to fundamental
models of materials (where the dimer represents a pair of atoms). Dimer
constants are factors in computing the partition function for the monomer-dimer
system. From the partition function, all thermodynamic properties such
as specific heat of a material can be computed from first principles. Thus,
this work fulfills a NIST goal of measuring fundamental physical quantities
of use to science and industry.
The two-dimensional constant was obtained analytically in 1961, while
the three-dimensional problem has defied exact solution. The approximate
solution by Beichl and Sullivan is based on the use of importance sampling
techniques to estimate the permanent of a related matrix. The computed
value, which comes with rigorous error bars, far exceeds the accuracy of
any previously obtained result. This work was just recently accepted for
publication in the Journal of Computational Physics. The techniques used
for approximating the permanent are expected to have wide application.
Nonlinear Dynamics of High-Speed Metal Cutting. High-speed machining
processes are increasingly important in modern manufacturing. However,
such processes can lead to discontinuous chip formation that is strongly
correlated with increased tool wear, degradation of the workpiece surface
finish, and less accuracy in the machined part. T. Burns of MCSD is collaborating
with M. Davies and C. Evans of the MEL Automated Production Technology
Division to develop a new approach to modeling some high-speed machining
processes that has the potential to predict the onset of discontinuities.
They have treated some basic metal cutting operations as nonlinear dynamical
systems that include a mechanism for thermomechanical feedback in the region
where the tool tip and workpiece material are in contact. The resulting
mathematical models share many similarities with models of open chemical
reactors. In a paper published in the Annals of the CIRP, Burns, Evans
and Davies showed that, as the cutting speed is increased, a bifurcation
from steady-state to oscillatory behavior occurs in computer simulations,
which is consistent with the change from continuous to segmented chip formation.
To obtain an analytical criterion for the material and cutting conditions
at which this bifurcation occurs, the researchers developed a related but
simpler lumped-parameter model. In a paper in Physical Review Letters,
Burns and Davies demonstrated that a Hopf bifurcation provides a dimensionless
group of parameters directly proportional to the cutting speed that predicts
the onset of discontinuous chip formation, and is consistent with experimental
observations on hardened steel and copper. Improvements in the models are
in progress.
This research is providing improved mathematical models for computer
simulation of manufacturing processes that involve high-speed cutting of
materials. Industry can use this information to control and improve the
machining processes. Burns and Davies were cited for this work in a joint
NIST Bronze Medal awarded in December 1998.
Industry Workshops Hosted. MCSD hosted three industry workshops
related to its technical work this year. The first was hosted by MCSD hosted
on August 11-12 in Boulder, CO with government, academic and industrial
participants to consider the formation of a consortium for the modeling
of electromagnetic scattering. Spearheaded by the Defense Advanced Research
Projects Agency (DARPA), the effort follows recognition that recent advances
in simulation methods for electromagnetics, centering primarily on the
fast multipole method, now have the potential to achieve a dramatic impact
on applied problems. These methods, developed in part by B. Alpert at NIST,
can reduce the computational complexity and improve the potential accuracy
of software for the solution of Maxwell's equations in quite general settings.
Existing codes, developed primarily as research tools, must be extended
and commercialized to achieve this potential. Industrial companies having
a substantial stake in low-observable (stealth) technologies, namely Boeing,
Lockheed-Martin, Northrup-Grumman, and Raytheon, sent representatives to
the workshop to discuss how such a consortium could be structured. Applications
beyond aircraft and missiles, including antennas, microelectronics, and
optoelectronics, were also discussed. MCSD anticipates a continuing role
in the formation of this consortium and helping to bring the benefits of
these algorithmic advances into broad commercial use.
The second workshop was the regional meeting of the Micromagnetic Modeling
Activity Group (muMAG) held at the NIST-Boulder Laboratories on August
27, 1998. MKE-Quantum co-sponsored the event, which drew about twenty-five
participants including representatives from Maxtor Corporation, Roscamp
Engineering and the University of Colorado, as well as from the NIST MSEL
and EEEL. MuMAG is an organization of industrial, government and academic
researchers investigating fundamental issues in micromagnetic modeling.
Among their activities are the establishment of standard problems for testing
micromagnetic simulation software, and the development of a public domain
reference implementation of micromagnetic simulation software. The latter
of these is the OOMMF package (described above), which MCSD's M. Donahue
and D. Porter demonstrated at the workshop. The workshop included talks
by industry representatives on the future micromagnetic modeling needs
of the computer hard drive industry.
Finally, MCSD hosted a meeting of the BLAS Technical Forum in Gaithersburg
on October 8-9, 1998. The forum is a consortium of industrial, academic
and government partners who are developing interface standards for Basic
Linear Algebra Subprograms (BLAS). The major aim of these standards is
to enable linear algebra libraries to interoperate efficiently and easily.
Obtaining high performance for core linear algebra operations is important
since these form the performance-critical portion of many numeric applications.
The BLAS for dense matrix operations in Fortran, which were developed by
researchers in the 1980s, have been widely adopted by commercial software
and hardware manufacturers. Subgroups within the forum are addressing extensions
into new areas such as sparse matrices and extended precision arithmetic,
as well as alternate language bindings for the legacy BLAS. The forum is
chaired by Professor Jack Dongarrra of the University of Tennessee at Knoxville.
Roldan Pozo of MCSD chairs the subcommittee on sparse BLAS, and MCSD is
developing a reference implementation of this portion of the standard.
The October meeting was attended by about 20 individuals, including representatives
from Intel, Hewlett-Packard, Tera, NAG, Inc., Bell Labs, NIST, the University
of Tennessee at Knoxville, the University of California at Berkeley, and
Florida Tech.
Support of the NIST Computing Environment. Division staff continues
to contribute to the high quality scientific computing environment for
NIST scientists and engineers via short-term consulting related to mathematics,
algorithms and software, and by the support of software libraries on central
systems. Division staff maintains a variety of research-grade public-domain
math software libraries on the NIST Central Computers (Cray, SGI Origin,
IBM SP2, etc.), as well as for NFS mounting by individual workstations.
Among the libraries supported are the NIST Core Math Library (CMLIB), the
SLATEC library, the NIST Standards Time Series and Regression Package (STARPAC),
and LAPACK. These libraries, as well as many others, are cross-indexed
for ease of discovery in the Guide
to Available Mathematical Software (GAMS), along with many other such
resources, by MCSD. This year, a major effort was undertaken in implementing
these libraries on the new NIST SGI Origin 2000 systems (in most cases
many versions of the libraries are maintained to support a variety of compilation
modes). This work is supported by the ITL High Performance Systems and
Services Division.
R. Pozo has continued his work in the development and use of PC clusters
for scientific computing. His JazzNet,
a "personal supercomputer" built from inexpensive, but high-performance,
Intel-based PCs running Linux and interconnected with fast ethernet and
PVM and MPI for message passing, pioneered the use of such systems at NIST.
JazzNet II containing18 processors, a fast ethernet switch and repeater,
was built in late 1997 for a cost of about $50K. A variety of division
applications have been ported to JazzNet, and the system has been
used extensively for program development. Several companies have recently
begun marketing rack-mounted PC clusters. JazzNet III will be one
of these systems, with eight 400 MHz Pentium processors (for 3.2 Gflops
peak performance), along with a combined 1 Gbyte of memory and 50 Gbytes
of disk, all for about $14K. Three such clusters have been purchased for
use in division projects. Because of the excellent price-performance of
these systems, we expect to see many more such systems in the NIST Labs
in the future.
Administrative Highlights
MCSD Division Chief Paul Boggs retired from NIST at the close of 1997.
During the succeeding eight months ITL Director Shukri Wakid, and MCSD
Group Leaders Ronald Boisvert and James Blue each served as Acting Division
Chief for periods of time. In late August 1998 Ronald Boisvert was named
the permanent Division Chief. Karin Remington was named the new leader
of the Mathematical Software Group. Unfortunately, Remington decided
to leave NIST in January 1999 to take a position with Celera Genomics.
The MCSD Compression Algorithms Group (CAG) is being merged with the
Multimedia and Digital Video Technologies Group (MDVTG) of ITL's Advanced
Networking Technologies Division (ANTD); the new group will reside in ANTD.
The move was seen as beneficial to both divisions. The CAG was a very small
group that was unlikely to grow significantly in MCSD. The CAG's work complements
the program of MDVTG, as well as other interests of the ANTD, and merging
the two groups is expected to provide increased synergy. Collaborative
efforts underway with other MCSD staff are expected to continue.
In September 1998 NRC Postdoctoral Appointee Donald Porter was converted
to a full-time permanent position in the MCSD Math Modeling Group. Finally,
John Gary of MCSD in Boulder retired in December 1998 after 15 years of
service at NBS/NIST.
External Recognition
Several staff members received significant awards this year. Anthony
Kearsley was one of two NIST staff members selected to receive the Presidential
Early Career Award for Scientists and Engineers from the National Science
and Technology Council. The award is given to those who, while early in
their careers, show exceptional potential for leadership at the frontiers
of scientific knowledge during the twenty-first century. He was cited for
his work in the application of optimization methods in a wide variety of
areas. (Roldan Pozo of MCSD won this award in 1996.) Timothy Burns received
the Department of Commerce's Bronze Medal for his joint work with Matt
Davies of the NIST Manufacturing Engineering Laboratory on the modeling
of high-speed metal cutting processes. Finally, G.W. (Pete) Stewart, a
faculty appointee from the University of Maryland, received the Bauer Prize
from the Technical University of Munich for his contributions to the field
of numerical linear algebra.

MCSD staff members continue to be active in publishing the results of their
research. This year 58 publications appeared which were (co-)authored by
Division staff, 30 of which appeared in refereed journals. In addition,
30 papers have been accepted, 21 of which will appear in refereed journals.
Another 28 manuscripts have been submitted for publication and 32 are being
developed.
MCSD staff members were also invited to give 33 lectures in a variety
of venues and contributed an additional 23 talks at conferences and workshops.
Web resources developed by MCSD continue to be among the most popular
at NIST. The MCSD Web server at math.nist.gov has serviced nearly 13 million
Web hits since 1994. The NIST Guide to Available Mathematical Software
(GAMS), a cross-index and virtual repository of mathematical software,
is used more than 10,000 times each month. During a recent 36-month period,
34 prominent research-oriented companies in the .com domain registered
more than 100 visits apiece to GAMS. The Matrix Market, a visual repository
of matrix data used in the comparative study of algorithms and software
for numerical linear algebra, sees more than 100 users each day. It has
distributed more than 10 Gbytes of matrix data since its inception in 1996.
Each of these Web services received Key Resource Awards from Links2Go this
year. (Links2Go makes awards based solely upon analysis of the number of
links to a given Web page in a given topic area.)
