The matrices with which I am working are very large and the current method which I employ involves the Eispack routine COMLR. Storage of the matrix is computationally expensive and scales roughly as n_s to the power 6 where n_s is of the order of 10. The matrices concerned are not sparse. I would be interested to hear of any recent developments in Lancos algorithms for complex, non-hermitian matrices which are known to be reliable for large matrices. All suggestions will be carefully considered and greatly appreciated. Susan E.

I want to find the PSD matrix that optimizes a certain function, so I need to parameterize the space of all NxN PSD matrices. If I map my parameter vector directly to the N*(N+1)/2 elements of a lower triangular matrix G then GG' is PSD, but this parameterization is not unique: G is a matrix square root, and is not unique. Therefore, I suspect that fewer than N*(N+1)/2 parameters are needed to span the space of all NxN PSD matrices. I seem to need a sort of inverse Cholesky factorization. Any comments or pointers would be greatly appreciated. Walter Prahl Phone: 212-756-1912 Sanford C. Bernstein & Co.

Dynamic load balancing is extremely important for efficient adaptive grid-based computations on distributed-memory multiprocessors. Numerical solutions to problems in computational fluid dynamics, computational chemistry, and semiconductor simulation involve the use of structured and/or unstructured grids. Parallel computation of such problems on distributed-memory machines typically entails two steps. First, as a preprocessing step, the computational mesh is partitioned into smaller submeshes. Second, the partitioned submeshes are assigned to processors based on a mapping strategy. While this static partitioning and mapping approach is appropriate for steady state calculations that do not change in computational intensity over time and space, it is grossly inefficient for unsteady, adaptive calculations. As the computational behavior changes non-uniformly, some processors may have a lot more work to perform than others. The imbalance in the computational load implies that the initial partitioning of the mesh is no longer efficient. It is therefore indispensable that the amount of work each processor performs be balanced at runtime in order to increase processor utilization and improve performance. Balancing the runtime computational load, however, is often very difficult due to many practical issues. These include a reliable measurement of the computational load, the amount of runtime data movement, and the minimization of inter-processor communication. The main purpose of this special issue is to report on state-of-the-art dynamic load balancing methods for real-world computational science and engineering problems. Topics of interest include, but not limited to, frameworks for global and/or local load balancing, comparative studies of load balancing methods, fast and high quality mesh partitioners, comparative studies of mesh partitioners, metrics for accurate load measurement, models to predict communication behaviors relevant to load balancing, discussions on the effects of load balancing on real-world problems, runtime data/workload distribution and migration methods to achieve load balancing, and parallel mesh adaption procedures. Authors should follow the JPDC manuscript format as described in the "Information for Authors" at the end of each issue of JPDC. The manuscript review process will be done electronically. A PostScript version of the manuscript should be sent to one of the co-guest editors by February 28, 1997. Authors will be notified of the review decision by July 31, 1997. Only original, unpublished work will be considered; manuscript resembling any previously published work in a journal are unacceptable.

Computational approaches for drug discovery and optimization have proven successful in many recent research programs. These methods have grown in their effectiveness not only because of improved understanding of the basic science --- the biological events and molecular interactions that define a target for therapeutic intervention --- but also because of advances in algorithms, representations, and mathematical procedures for studying such processes. This workshop will bring together top researchers in computer-aided drug discovery, computational chemistry, mathematics, and computer science to present state-of-the-art research in both the science and the underlying mathematics, and to identify new problems for possible collaborations. General subject areas of the workshop will include receptor-based applications such as binding energy approximations, molecular docking, and de novo design; non-receptor-based applications such as molecular similarity, conformational analysis, and structural diversity; molecular dynamics simulations and protein folding simulations; plus related issues such as drug-delivery modelling and scientific visualization. The workshop will also focus on the mathematical procedures and algorithms upon which the scientific applications are based. These include graph theory and topology, non-linear multidimensional optimization, the processing and representation of information obtained from simulation studies, global optimization and search strategies, plus performance enhancement through parallel computing architectures. In addition to the oral presentations, the workshop will also include two panel discussions, one examining the most important current problems in drug design that may be computationally tractable, and the second on emerging areas of study in which improvements in scientific knowledge over the next few years may enable the fruitful application of computational methods. The overall goal of this workshop is to bring together scientists and mathematicians to examine the current state of this very broad and interdisciplinary field of research, and to identify the areas where cross-fertilization of ideas and collaborative research might most effectively advance the field.

OPTI 97 CONFERENCE The practical applications of structural optimisation techniques which are well recognised by industry offer important advantages in the design of aircraft and are used in the analysis of automotive, civil and mechanical engineering components. Computer-aided structural design is enhanced by adding optimisation software and its influence cannot be over emphasised. By linking both techniques, integrated packages for structural optimisation are obtained. The objective of this Conference is to bring together researchers and engineers in order to communicate recent advances in structural optimisation, and also to demonstrate how optimisation can be applied in engineering practice.

These environments will not only make specialized and geographically distributed resources easily accessible at the desk-top for everybody, but will also ameliorate their utilization, thus contributing to improved economics of high-performance computing resources in particular. In the long run, they will also change the way we work in research and business. The 21st SPEEDUP workshop aims at providing a forum for members of academic institutions and business enterprises to meet and to discuss and learn about the latest developments related to all aspects of distributed computing and distributed applications. Topics to be covered include but will not be limited to -- Programming models, tools, and environments -- Development and management of distributed applications -- Performance evaluation, tuning, and benchmarking -- Task distribution and load balancing -- Application responsiveness and scalability -- Enabling technologies -- Distributed information systems -- Very large databases -- Resource management and configuration -- Authentication and security -- Reliability -- Cooperative design and development methods -- Tele-working and collaborative environments The proceedings of the workshop will be published in the first 1997 issue of the SPEEDUP, to appear in April/May 1997. In 1997, the SPEEDUP will become ten years old. Therefore, in conjunction with the 21st SPEEDUP workshop, we will also celebrate the 10th anniversary of the SPEEDUP Initiative. Several key note speakers will address the history, the status, and the future perspectives of high-performance computing in Switzerland.

The aim of the conference is to bring together scientifists with interests in theoretical, applied and computational aspects of hyperbolic partial differential equations. There will be an amphasis on nonlinear problems and applications in different fields. As it has been done in past, a special effort will be made to make it possible for young scientists to attend to promote their interaction with the more senior researchers.

These conferences have traditionally covered the numerical and algorithmic aspects of Scientific Computing, with a strong emphasis on the algorithmic validation of results and on algorithmic and arithmetic tools for this purpose. Validation or verification characterizes those efforts in Scientific Computing which strive to generate - concurrently with numerical results - qualitative and quantitative assertions about the results which are correct in a rigorous mathematical sense. Typical examples of such efforts are the specification of a domain in which a solution of a given problem exists and the computation of close upper and lower bounds for the result of a given problem. Assertions from algorithmic validation have the same correctness quality as assertions obtained by classical mathematical methods of derivation and proof. Because of this quality, Validated Numerics has developed into an important subject within the fast growing area of Scientific Computing. SCAN-97 will provide a forum for the presentation of the latest research and developments in theory, algorithmic and arithmetic design for Validated Numerics, demonstration of new software available for Validated Numerics, reporting of interesting case studies in industrial and scientific applications of Validated Numerics, and for the discussion of new directions in research and development suggested by other advances in Scientific Computing. Potential new directions are the use of parallel architectures for the implementation of validation algorithms and the use of validation ideas in Computer Algebra. Furthermore, the conference should help in the dissemination of the ideas and potentials of Validated Numerics to interested scientists from other areas of Scientific Computing. Within the scope of SCAN-97, there is no restriction regarding the mathematical or applicational background of the problems to be reported: Algebra, analysis, optimization, probability, etc., are equally welcome.
