This seems like a good idea and so here is the first NA Digest Calendar. We'll include the Calendar in the NA Digest about once a month, and we'll list all the meetings, conferences and workshops that have been announced in recent issues. I've compiled this from issues 1-14 of the 1994 Digest, but I may have missed some announcements, and there are probably other relvant meetings. So, if I missed one, or you have one that should be included, please drop me a note. -- Cleve] NA Digest Vol 94, # Apr. 13-15 NAG Users Association Oxford, UK 4 Apr. 15 Southern Ontario NA Day Toronto, Canada 15 Apr. 18-22 Multigrid Canberra, Australia 10 Apr. 24-24 Object-Oriented Numerics Sunriver, OR 6 Apr. 24-28 Computational Medicine & Public Health Austin, TX 15 Apr. 24-28 Wave Propagation Juan-les-Pins, France 8 Apr. 25-26 Domain-Based Parallelism Minneapolis, MN 7 May 1-5 Applied Computational Fluid Dynamics Basel, Switzerland 15 May 16-20 Mathematic Problems in Industry Boulder, CO 6 May 19-20 Annual PVM Users' Group Meeting Oak Ridge, TN 15 May 16-18 Spectral Multi-Domain Workshop Raleigh, NC 14 May 23-25 Parallel Numerical Algorithms Hampton, VA 4 June 2-3 Computational Fluid Dynamics Toronto, Canada 2 June 6-10 Applied and Industrial Mathematics Linkoping, Sweden 14 June 6-14 Mathematics Modeling Workshop Claremont, CA 9 June 6-8 Supercomputing Symposium '94 Toronto, Canada 2 June 11-15 Continuous Algorithms and Complexity Mount Holyoke, MA 13 June 15-18 SIAM Applied Linear Algebra Park City, UT ..

Is it a department, a special program within a department, an interdisciplinary program? Is it located in the College of Engineering, a College of Liberal Arts, or where? Is it just a graduate program, or are undergraduate programs being developed? What kind of faculty are associated with formal institutional programs in Scientific Computing? What kinds of curriculum are being developed? Is Scientific Computing being combined with other areas, e.g. general applied mathematics, CFD, etc? I would welcome any information you have. Because of local interests, I will try to develop a summary of what I receive, to give some kind of overview. Thanks, Ken Atkinson Dept of Mathematics University of Iowa Iowa City, Iowa 52242 ------------------------------ From: Jonathan Shewchuk Date: Mon, 04 Apr 94 13:07:32 -0400 Subject: Conjugate Gradients Made (Almost) Easy Now available by FTP: An Introduction to the Conjugate Gradient Method Without the Agonizing Pain Jonathan Richard Shewchuk jrs@cs.cmu.edu 55 pages, >> 62 illustrations << This technical report is the most intuitive, figure-filled introduction to the Conjugate Gradient Method I am capable of writing. I've designed it both for interested people who want a good basis for understanding iterative methods and their convergence analysis, and for teachers who want to include CG in their courses. This report is being used in graduate courses in the Computer Science and Civil Engineering departments here at Carnegie Mellon. A separate file is available that contains full-page copies of the figures, suitable for transparencies. The idea of quadratic forms is introduced and used to derive the methods of Steepest Descent, Conjugate Directions, and Conjugate Gradients. Eigenvectors are explained and used to examine the convergence of the Jacobi Method, Steepest Descent, and Conjugate Gradients. Other topics include preconditioning and the nonlinear Conjugate Gradient Method. I have taken pains to make this article easy to read. Sixty-two illustrations are provided. Dense prose is avoided. Concepts are explained in several different ways. Most equations are coupled with an intuitive interpretation. The report is available by anonymous FTP to REPORTS.ADM.CS.CMU.EDU (IP address 128.2.222.79) under the filename 1994/CMU-CS-94-125.ps . Comments and corrections are welcome. ------------------------------ From: Cleve Moler Date: Sun, 3 Apr 1994 13:55:51 -0400 Subject: Bessel Function Suite for MATLAB A new suite of routines for computing Bessel functions is now available for MATLAB. The core of the suite is a Fortran MEX file based on a Bessel function library written by D. E. Amos at Sandia National Laboratory several years ago. Several M-file functions provide access to the Fortran core. Bessel functions of complex argument are fully supported. Both the index and the argument can be arrays, so entire tables or basis sets can be generated with one statement. The primary functions in the suite are: BESSELJ(NU,Z) Bessel functions of the first kind, BESSELY(NU,Z) Bessel functions of the second kind, BESSELI(NU,Z) Modified Bessel functions of the first kind, BESSELK(NU,Z) Modified Bessel functions of the second kind, BESSELH(NU,K,Z) Hankel functions, AIRY(K,Z) Airy functions. BESSELMX(...) The Fortran MEX file core library. The Bessel suite is distributed via anonymous FTP from ftp.mathworks.com (144.212.100.10) in directory pub/mathworks/toolbox/matlab/specfun -- Cleve Moler moler@mathworks.com ------------------------------ From: Cleve Moler Date: Sun, 3 Apr 1994 13:56:14 -0400 Subject: Harwell-Boeing Connection to MATLAB New software is available which facilitates MATLAB access to sparse matrices in the Harwell-Boeing Sparse Matrix collection. The Harwell Boeing collection is available via anonymous FTP from the CERFACS research laboratory in France: orion.cerfacs.fr (130.63.200.33) The collection is in directory pub/harwell_boeing A compressed, postscript file contained a detailed user's guide is pub/harwell_boeing/userguide.ps.Z The new conversion software is available via anonymous FTP from the MathWorks: ftp.mathworks.com (144.212.100.10) There are two files in directory pub/mathworks/toolbox/matlab/sparse The first file is hbo2mat.f, Fortran source code for a stand alone program which reads Harwell-Boeing data files and uses the MATLAB External Interface Library to convert them to .mat files. The second file is hbo.m, a MATLAB function which loads one of the .mat files and completes the conversion. -- Cleve Moler moler@mathworks.com ------------------------------ From: Joke Blom Date: Tue, 5 Apr 1994 13:17:06 GMT Subject: Adaptive Grid Solvers Available ADAPTIVE GRID SOLVERS FOR PDES IN 2D AND 3D To solve time-dependent partial differential equations often a straightforward Method of Lines approach is used. The PDE is discretized in space and the resulting system of ODEs is solved in time with a robust `off-the-shelf' solver. The spatial grid used can be either uniform or nonuniform but is invariable for the time interval. For problems with steep and moving fronts this can be an inefficient approach since too much grid points are needed at areas where the solution (no longer) has large spatial gradients. For this class of problems we have developed at CWI the software package VLUGR, a (vectorizable) adaptive-grid finite-difference solver for time-dependent PDEs in 2 or 3 space dimensions. The PDEs should be defined on an arbitrary domain bounded by right-angled polygons (2D) or polyhedrons (3D). The spatial operator may contain at most second-order derivatives (including mixed derivatives). To resolve the steep gradients in the solution Local Uniform Grid Refinement has been employed. At each time level the domain is covered by a, uniform, coarse base grid and nested finer uniform subgrids are recursively created in regions with high spatial activity. The corresponding initial boundary value problem for each grid level is solved with an implicit time integrator (BDF2). The packages VLUGR2 (for PDEs in 2D) and VLUGR3 (3D) are written in ANSI Fortran 77. HOW TO GET IT 1) Via World-Wide Web. Open the URL http://www.cwi.nl/ftp/gollum and then select the package you desire. 2) Via anonymous ftp at ftp.cwi.nl (192.16.184.180) Change directory to pub/gollum/VLUGR2 or pub/gollum/VLUGR3 The directories contain a README file, the compressed shar file of the source, and the compressed postscript files with the papers describing the algorithms, the code, and how to use it.
