The matrix is sparsed, highly non symetric, and the number of non zero elements is bigger than 500000. We have thought of an iterative system to find the solution, but most of the methods work well for symetric matrices. Does anyone know any efficient iterative method for this kind of problems. Thanks in advance for any answer.

The first edition of this book, published in 1988 by Prentice-Hall, became unavailable in 1993. The current edition contains many small corrections but no major ones. Also, it's in a softcover volume and is significantly cheaper than the original edition. Those of you who are interested in this field may find the book very helpful. Please feel free to contact SIAM for further information: siam@siam.org ISBN 0-89871-354-4 Uri Ascher, Bob Mattheij and Bob Russell ------------------------------ From: Niels Houbak Date: Fri, 6 Oct 95 16:42:58 MET Subject: Simulation Language, SIL, Available via FTP Dear NA-friends, The SIL system (SIL stands for SImulation Language) might be of interest for some of you. It has now passed several years of testing by students at DTU and I therefore invites you to try it out. It runs only (unfortunately) under DOS (on IBM compatible PCs) and can be used for solving - Algebraic Equations - ODEs (y'=f(t,y) or 0=f(t,y,y'); stiff or non-stiff) - DAEs (only index 1) - Discontinuous ODEs, and - Non-linear datafitting problems. The ODEs are integrated using STRIDE (version 1.x) and they are displayed graphically (and interactively). A special (PASCAL-like) input language is used for stating the equations. Range checking on selected variables can be imposed. A version of the code is available via anonymous FTP from the site lfe.mnet.dtu.dk . (IP 130.225.89.137) REMEMBER to use Binary transfer mode! Copy all files from the SIL directory and the two subdirectories SIL/DEMO and SIL/EXAMP . The users guide can be found in N. Houbak: SIL - a Simulation Language, Users Guide. Lecture Notes in Computer Science, Springer Verlag, Vol. 426, 1990. Please send comments and questions to: Niels.Houbak@lfe.dtu.dk Happy simulations Niels Houbak. ------------------------------ From: George Miminis Date: Fri, 6 Oct 95 15:51 EET Subject: Zetta Tsaltas Dear colleagues, I need to share the following with you, especially with those that know me. On the 8th of August while me and my family (my wife Zetta and our kids Simon and Leto) were on vacation at the Greek island of Lemnos, my wife Zetta lost her life on a car accident. Zetta had successfully defended her Ph.D. on Cancer Research last December. Zetta completed her Ph.D. while at the same time she was working full time and raising two children (Simon 7 years old and Leto 4.5). She was intelligent, loving and caring. I had found the life time partner we all dream of. I was proud of my wife and those that know me also know that I would not miss a chance to talk about her achievements. The last academic year 1994-95, we started working together on an interdisciplinary project entitled "Mathematical Modeling in Cancer Research: Simulation and Control". Although this was a rather general title, we started by attempting to determine an optimal schedule (including the dosage) of delivering a specific drug to specific cancer cells. The project had been partially funded by NSERC and Memorial University. We had been seeking though complete funding, actually the results of a grant application for this project are still pending. The project had also created enough interest in the local community so that an article was published in the local newspaper entitled "Cancer Research combines Computer Science and Biology". We were to spend the current academic year in Toronto. Zetta had got a postdoctoral position at the Toronto general hospital working on Gene Therapy for Cancer and I had arranged to spend my sabbatical year at the Toronto university, department of Computer Science. Due to the unfortunate circumstances though me and my kids will spend the current academic year at 57 Panioniou str. Kesariani, Athens, 161 21, Greece. My e-mail address "miminis@cs.mun.ca" still works. I met Zetta in Montreal in February 1983, although we spent together 12.5 happy years, I feel she went by my life like a comet. She combined the glory and the excitement of her arrival, the happy and productive activities of her stay and the disappointment of her departure. Too bad it was a once in a life time event. The following statement comes from the bottom of my heart: Dear Zetta, for our two beautiful kids you brought in life, for the good and the difficult times, for the happy and the sad times, for 12.5 fulfilling years I thank you. Wherever you are, rest in pease, have fun and please know that I will love you eternally.

Preliminary Programme "Can Static Load Balancing Algorithms Be Appropriate in a Dynamic Setting?" Bruce Hendrickson (Sandia National Laboratory) "Variants of the Spectral Bisection Technique Suited for Dynamic Load Balancing" Dirk Roose (KU Leuven, Belgium) "Parallel Mesh Partitioning" Chris Walshaw (University of Greenwich) ``Towards Parallel Dynamic Load Balancing for Adaptive PDE solvers", Peter Jimack (University of Leeds) "Some Algorithms for Dynamic Load Balancing" Yifan Hu (Daresbury Laboratory) It is also hoped to have speakers from industries. Additional contributions, particularly in the form of posters, are welcome. The workshop will seek to identify the current status of dynamic load balancing on parallel systems. It will focus on MPP systems such as the Cray T3D, Intel Paragon and IBM SP2, although the issues addressed would be equally applicable to workstation clusters. It will establish current practice and illustrate the challenges facing both academic and industrial researchers. The workshop will also seek to identify the issues involved in achieving efficient dynamic load balancing strategies on existing or future machines.
