A R Mitchell Fund The 1991 Dundee Numerical Analysis Conference celebrated the 70th birthday of A R Mitchell. In addition to his distinguished contributions to numerical analysis extending over many years, Ron has been known for the outstanding encouragement he has given to young numerical analysts and the Organizing Committee therefore felt it appropriate to mark his birthday by instituting a special fund to provide assistance to young numerical analysts to attend Dundee meetings. There are no formal means of applying for support from the fund but the organisers welcome enquiries from anyone who feels that they may be eligible. Allocation of funds will be made on the basis of need, and also on the basis of abstracts of papers intended for presentation at the conference. We would like to thank those who have contributed generously to this fund and we again appeal to colleagues for contributions. Cheques should be made payable to "The University of Dundee: A R Mitchell Fund". ------------------------------ From: Simon Chandler-Wilde Date: Wed, 23 Dec 92 21:11:50 GMT Subject: Northern Universities' Numerical Analysis Day NORTHERN UNIVERSITIES' NUMERICAL ANALYSIS DAY Thursday 7th January University of Bradford Outline of the Programme Meeting begins at 10 a.m. "An Optimal Positive Definite Update for Sparse Hessian Matrices" Roger Fletcher, University of Dundee "Acceleration of Convergence of a Sequence of Vectors" Peter Graves-Morris, University of Bradford "A Pseudospectral 3D Boundary Integral Method Applied to a Nonlinear Model Problem From Finite Elasticity", Ivan Graham, University of Bath "Singularities of Solutions of Abel-Volterra and Abel-Fredholm Integral Equations", Donald Kershaw, University of Lancaster "Boundary Integral Methods for the Helmholtz Equation in Exterior Domains", Sia Amini, University of Salford "An Iterative Variant of a Chebyshev Collocation Method for Symm's Integral Equation on an Open Arc" Jeremy Levesley, University of Leicester For further details contact Simon Chandler-Wilde, Department of Civil Engineering, University of Bradford (Email: S.N.Chandler-Wilde@uk.ac.bradford) ------------------------------ From: George Cybenko Date: Tue, 22 Dec 1992 21:11:16 -0500 Subject: Symposium on Parallel I/O and Databases Dartmouth Institute for Advanced Graduate Studies, 1993 Issues and Obstacles in the Practical Implementation of Parallel Algorithms and the Use of Parallel Machines Symposium: Parallel I/O and Databases School in Parallel Programming June 21-June 30, 1993 Hanover, New Hampshire This summer, Dartmouth will hold its second DAGS institute to promote the use of high performance computing.

The Parallel Circus is an informal meeting, with the program planned on the morning of the first day. Many long-time attendees of the Circus commented that this was the ``best Circus ever'' in terms of organization and quality of the presentations. A most enjoyable time was had by all. Many thanks to the organizers, Tim Kelley, Bruce Loftis, Bob Plemmons and Gene Golub, with special thanks to moderator Gene Golub and to local host Bruce Loftis at the supercomputing center. The talks were primarily concerned with ``parallel numerical algorithms'' and ``parallel software and hardware performance.'' Some speakers have provided abstracts of their presentations and these are given in an appendix. Many thanks to Chuck Baldwin, whose preliminary report appears (with some minor editing) in the section below. Summary of Presentations ------------------------ Friday started out with a number of talks related to eigenvalues. The first, entitled ``Parallel Eigensolvers Based on Homotopy Continuation'' was given by Zhonggang Zeng from Northern Illinois. This talk focused on using ODE methods to compute eigenvalues of an unknown matrix from those of a closely related matrix whose eigenvalues are either known or easily computed. The second talk of the day was by Charles Fulton of the Florida Institute of Technology and was titled ``Parallel Computation of Spectral Density Functions for Sturm-Liouville Problems.'' This talk described a package called SLEDGE - Sturm-Liouville Estimates Determined by Global Errors -- and it's implementation on an Intel iPSC/860. Gary Howell, also of the FIT, next discussed ``An Adapted Bandwidth Algorithm for Stable* Reduction to (Near) Tridiagonal Form.'' His talk focused on using Gaussian Transforms to obtain solutions to Sylvesters Equation, AX + XB = C. Fourth up was a talk by Kevin Gates from ETH on ``A Rank-Two Divide and Conquer Algorithm for the Symmetric Tridiagonal Eigenvalue Problem.'' He presented the basics of an algorithm similar to Cuppen's algorithm, but is based on rank two updates. Numerical comparisons of several algorithms were given and show the new algorithm to be competitive. ``A Homotopy Method for Solving Riccati Equations on a Shared Memory Parallel Computer'' by Dragan Zlgic of Virginia Tech was next up. This work was also concerned with using Homotopy methods for finding eigenvalues of a matrix by using a related matrix and solving the Riccati equations, AX + XA^T - XX + R = 0. Christopher Sprenger presented a two part talk entitled ``Parallel QR/Sciddle: A System for Asynchronous Remote Procedure Call''. Gong Chen was next with a talk titled ``A Highly Parallel Algorithm for Hessenberg Reduction.'' This talk described work done on an Intel iPSC/860 to find methods for reducing matrices to Hessenburg form by partitioning schemes suited to distributed memory type machines and follows work done by Dongarra and van de Geijn. George Pitts next gave a talk titled ``Strategies for Parallelizing PDE software.'' This work investigated using Explicit Parallelization, Automatic Parallelization, and a mixture of the two. Performance-critical ``kernel'' routines are hand coded and applied to various routines from ELLPACK. ``Parallel Direct Solution of Indefinite Systems of PDEs Discretized with Finite Element/Spectral Methods'' by Reza Mehrabi of MIT was next up. Here a crystal growth program was ported to the iPSC/860 which used direct methods along with nested bisection in 2D to obtain Finite Element solutions. ``A New Family of Preconditioners for Domain Decomposition'' by Mo Mu of Purdue was next up. This work involved using rational functions as preconditioners for elliptic problems with two different regions in 2D. Victor Eijkhout of Tennessee was next with ``Observations about Distributed Iterative Methods.'' This work described work done on parallelizing iterative solvers on distributed memory machines and gives a new variant of CG which reduces synchronization effects. ``Parallel Evaluation of Rational Matrix Functions'' was presented by Lothar Reichel of Kent State. This presentation was on joint work with Stratis and D. Calvetti. The work utilizes Partial Fraction Representations to solve problems derived from elliptic operators and considers some problems and possible solutions which involve poles which are close in the partial fraction representation. The last talk of the day was ``PYRROS: Static Scheduling and Code Generation for Parallel Programs'' by the ETH group in Switzerland. This was an overview of the PYRROS project and included discussions of how PYRROS maps tasks to processors and schedules those tasks. During the day (Friday) we had a tour of the North Carolina Supercomputer Center in which we were introduced to the new 32 processor Kendall Square machine at NCSC. The new machine utilizes a ring topology and, with multiple rings scales to 1088 processors. The machine is up and running, but some refinement to the software environment is in progress. Saturday was a short day and involved several software related topics. The morning started out with ``Prototyping Parallel Algorithms'' by Lars Nylend of UNC Chapel Hill. This talk detailed a system called Proteus which is a language for parallel programming with specific attention paid to data parallelism, and loosely synchronous parallel execution - an example program of the N body problem was given. ``Scheduling Regular and Irregular Computations on the CM-5'' by Rajeev Thakur was up next. This describes an algorithms for global communications on the CM-5 with superior performance. Next on the schedule was ``A Proximal Based Decomposition Method for Convex Minimization'' by Gong Chen of Maryland. This involved using the fact that convex minimization was equivalent to solving a mini-max problem via a new method that the authors are developing. ``Component Analysis Based on Serial Results for Analyzing Parallel Iterative Performances'' by Shu-Mei Richman of the University of Virginia was next. This was an investigation of GMRES and BiCG based on parameters usually involved in iterative methods (Preconditioning methods, residual tolerance, problem size, number of processors). ``Distributing Symbolic Computations'' was next given by Todd Torgersen of Wake Forest. An overview of ALTS - a system for distributing symbolic computations was given. ``Improvement of Communications Bandwidth Using the Forced Message Type'' by Xinglai Zhuang of Mississippi State was next. This involved a study of various global communication operations using two different methodologies on the Intel iPSC/860. The program continues with ``Solving Large Systems of Linear Equations using Asynchronous Iterations on Distributed MIMD Computers'' by J. Nieplocha of the University of Alabama. This was a overview of issues which regularly come up in asynchronous communications on MIMD computers such as communication load, convergence of an algorithm, and load balancing. Robert White of NC State next gave a talk on general issues related to parallelizing grand challenge codes, the convection-diffusion type equation was used as an example. ``A Parallel Algorithm to Calculate Smooth Boundary Conditions for a Domain Decomposition Method'' by Kelly Black of NC State was up next. This talk examined using Chebyschev Collocation on parabolic problems with interfaces on the interior of a region. ``Orbit Prediction on Parallel Computers'' by Beny Neta of the Naval Postgraduate School was next on the hit parade. This was a talk of using an Intel iPSC to develop more parallel algorithms for accurately predict orbits. Last was Roldan Pozo of the University of Tennessee with ``Object Oriented Scalable Linear Algebra in C++''. This was a talk of work done in connection with the LAPACK project to have an object oriented version available soon and how it could be of use to people. ============================================================================= || The Thirteenth Parallel Circus is planned for April at the University || || of Illinois CSRD in Champaign-Urbana. || ============================================================================= ------------------------------ From: SIAM Date: Wed, 23 Dec 92 09:37:39 EST Subject: Season's Greetings from SIAM ' SSS EEEEE A SSS OOO N N SSS S S E A A S S O O N N N S S SS EEE A A SS O O N N N SS SS E AAAAA SS O O N N N SS S S E A A S S O O N NN S S SSS EEEEE A A SSS OOO N N SSS GGGGGG RRRRR EEEEE EEEEE TTTTTTT IIIII N N GGGGGG SSS G R R E E T I N N N G S S G R RRR EEEE EEEE T I N N N G SS G GG R R E E T I N N N G GG SS G G R R E E T I N NN G G S S GGGGGG R R EEEEE EEEEE T IIIII N N GGGGGG SSS FFFFFF RRRRR OOO MM MM F R R O O M M M M FFFF R RRR O O M M M F R R O O M M F R R O O M M F R R OOO M M SSS IIIII A MM MM S S I A A M M M M SS I A A M M M SS I AAAAA M M S S I A A M M SSS IIIII A A M M [ ... and from all of us at NA Net. -- Cleve] ------------------------------ End of NA Digest ************************** -------
