This Institute will provide a forum for scientists to meet and learn from leading researchers about the latest advances in computational methods and algorithmic developments in a number of important disciplines in engineering and science. In addition, participants will benefit from hands-on sessions using the parallel supercomputer resources of the Center's Cornell National Supercomputer Facility (CNSF) and from opportunities for informal interaction among themselves and with the invited speakers. 1989 Summer Institute The Summer Institute runs for two weeks and is held on the Cornell University campus. The program consists of four distinct components: lectures by leading experts in computational science; training in use of the CNSF facilities, hands-on lab sessions for individual appli- cations; and informal interaction among participants and speakers. Lectures: Lectures will be given by industrial researchers with outstanding reputations and experience on the IBM 3090, Cornell faculty who are experts in computational science, and current CNSF researchers. To date, the list of committed speakers from IBM includes Enrico Clementi, Augustin Dubrulle, Jeno Gazdag, Fred Gustavson, William Henshaw, Steven Laux and Don Weingarten. Additional speakers have been invited, and we are awaiting final commitments. A partial list of topics includes: Computational Physics: o Algorithms for Lattice Quantum Chromo Dynamics (QCD) Calculations o Implementation of QCD Algorithms on the GF11 Parallel Computer o Monte Carlo Methods for Sub-micron Device Simulation Computational Fluid Dynamics: o On the Smallest Scale of Turbulence o Solution of Navier-Stokes Equations on Composite Overlapping Meshes Computational Mathematics: o Concurrent Computing by Sequential Staging of Tasks o The Key Algorithms in the Parallel ESSL Library o Future Directions in Sparse Matrix Computations o Unite-and-Conquer Algorithms for the Solution of Systems of Equations Computational Chemistry: o Molecular Dynamics and Monte Carlo Programs for Proteins and Nucleic Acids in Solution o Chemical Application in Fluid Dynamics o Micro-dynamics The theme of computational methods will provide the common thread running through all of these lectures. Training: Training in the use of the CNSF will cover the VM/CMS architecture and operating system, concepts and techniques in parallel processing and vectorization, methods of converting serial code to parallel, and tools for analyzing code performance. Lab Sessions: Lab sessions are planned to allow participants to apply the concepts discussed in lectures to their own projects. Participants will each be allocated 10 service units (20 CPU hours on the IBM 3090) to be used during the workshop and later in continuing work at their home sites. Lecture materials will be given to each participant, and CNSF staff will be available for consultation throughout the program. Informal Interaction: Ample time is planned to allow for informal interaction among the participants and invited speakers throughout the program. Speakers will also be invited to attend lab sessions to learn about participant codes and to provide guidance. Institute Facilities The CNSF configuration consists of two IBM 3090-600E supercomputers, each with six vector facilities, and a peak performance rate of 696 megaflops. (The IBM system has 256 MBytes of memory, 512 MBytes of expanded storage, and 115 GBytes of disk storage. Each application may use up to 1 GByte of virtual memory.) The current operating system is VM/XA SP (CMS) and the primary language is FORTRAN. The CNSF system provides unique production parallel processing capabilities. An appli- cation can simultaneously run on six processors using parallelism at both the loop and task levels while taking full advantage of the large virtual memory and vector facilities of the 3090. The Cornell Theory Center The Center for Theory and Simulation in Science and Engineering -the Cornell Theory Center - was established in 1984. One of five National Science Foundation-sponsored National Advanced Scientific Centers, the Theory Center was created to advance science and technology by making the most highly advanced computers more accessible to researchers. As part of this effort, the Theory Center is committed to educating students, scientists and engineers in the use of supercomputers. The facility supports about 1,800 users working on more than 460 research projects in the fields of quantum chemistry, theoretical and applied physics, ecological studies, econometric modeling, biomedicine, and the social sciences, as well as all areas of engineering. Application Requirements Enrollment is limited to 30 participants. Selected applicants will be graduate students, post-doctoral researchers or university faculty members who are actively engaged in projects which rely heavily on the efficiency of computational methods and algorithms as well as vector, parallel, and memory capabilities. Participants should bring working versions of their codes which include only the most critical algorithms in their applications. These working codes should be written in ANSI FORTRAN 77, and contain minimal machine dependencies. CNSF staff will provide assistance in migrating code and data to the IBM 3090 prior to the start of the Institute. Provisions and Accommodations Under the NSF grant for the Institute, participants will be reimbursed for travel expenses; housing and meals will be provided. Details will be supplied upon acceptance.

This brought me a pile of responses: All (except one) were fully in agree- ment with my position; many indicated that they may or will not attend under these circumstances. There were some very well-known numerical analysts amongst those responding. Also, two members of the Organisation Committee (= program committee) told me that they have been fighting with IMA about these excessive fees for some time but without success, and that they would appreciate support. May I therefore suggest the following: Everybody who has considered or planned to go to London and who agrees that these fees are completely out of proposition for a scientific conference held at a university, should write a letter to the Institute of Mathematics and its Applications. Just to stay away or to complain to colleagues will have no effect; IMA must be made aware of the situation. You may also quote registration fees of comparable conferences to point out the discrepancy. E.g., the last Computational ODE Conference at Toronto (1988) which was fully comparable in size and scope with the London Meeting, had a registration fee below 50 US $, viz. 50 CAN $. (Besides, the information received with the application form is quite lacunary. E.g. what quality of accomodation the residential fee will buy is not even indicated. Thus, the organisation of the conference is not even done in a professional manner.) Your action should come very soon in order to be effective, it will be a service to the whole Numerical Analysis community. Sincerely, Hans J. Stetter ------------------------------ From: Gene Golub Date: Fri, 14 Apr 1989 15:56:37 PDT Subject: SIAM Journal on MATRIX ANALYSIS AND APPLICATIONS The SIAM Journal on Matrix Analysis and Applications (SIMAX) is approaching the middle of its second year. I'd like to update you on our progress. SIMAX is still a very new journal and the style of the journal is still developing. We continue to focus on the matrix research that has to do with applications to areas such as signal processing, systems and control theory, statistics, Markov chains, mathematical programming, economic and biological modeling. We encourage you to submit your articles to us, especially in those areas of unusual application. In general, our editorial board members have been successful in receiving prompt reviews of journal submissions. We are taking steps to remedy the delicate problem of delayed reviews. Our waiting time from acceptance to publication is six to nine months and it is our intention to maintain this processing time. We want you to know that every issue will contain articles of interest to each of our subscribers. Thus, as a matter of policy, we do not plan to devote more than a partial issue to any special topic. You may now submit your accepted manuscripts in Tex, LATex, and AMS-Tex. SIAM journal macros are available through Net-lib and directly from SIAM via e-mail and floppy disk. Although authors may need to spend some time making editorial changes, there are advantages in submitting your manuscripts to us in Tex. First, the author retains greater control over the final appearance of his manuscript. Second, the introduction of errors from a second keyboarding is avoided. Third, one round of proofreading is eliminated. Fourth, authors who typeset their own articles receive 100 gratis reprints. Circulation for SIMAX has increased nicely during the past year--we now have over 1100 subscriptions and we expect that number to continue to increase at a reasonable rate for the next several years. SIMAX is an affordable journal. The current subscription rate for SIAM individual members is $36 ($39 for individual members outside the United States, Canada, and Mexico). The institutional rate is $95 ($118 for institutions outside the United States, Canada, and Mexico). You can have the issues of your personal subscription to SIMAX delivered to your home or office. Institutions may order several subscriptions delivered to addresses they designate. Our academic members receive a subscription to SIMAX as a part of their membership. Of course, we encourage you to request your local library to subscribe to SIMAX. Remember, for those of you who are SIAM members, SIMAX is your journal. For those of you who are not members, please consider joining SIAM and subscribe to SIMAX at the member rate. We will always welcome your help, advice, and submissions. Sincerely, Gene Golub Managing Editor SIAM Journal on Matrix Analysis and Applications Postscripts: Please submit your manuscripts to: SIAM Publications, P.O. Box 7541, Philadelphia, PA 19101. Requests for journal macros should be sent by e-mail to Corey Gray at SIAM@WHARTON.UPENN.EDU or by mail to Corey Gray at SIAM, 117 South 17th Street, Philadelphia, PA 19103-5052.
