The Math-Net Links belong to the first steps of the "Konrad-Zuse-Zentrum fuer Informationstechnik Berlin" (ZIB) towards a "Distributed Information System for Mathematics", a project planned by the "Deutsche Mathematiker-Vereinigung" (DMV) for the years from 1996 to 1998. We will integrate the Math-Net Links into the server of the International Mathematical Union (IMU) which is being build up at present by ZIB. You may find the related URLs in the homepage of the Math-Net Links. Naturally, we hope for suggestions, comments, and also critizism from you in order to maintain this service in the long run, and to keep it up-to-date. An activity of this kind lives from world wide contributions. We hope that you have an idea how to improve this service. Best regards, Joachim Luegger ------------------------------ From: Alexander Puhov Date: Mon, 18 Sep 1995 11:18:10 +0200 (MET DST) Subject: Seeking Simple Graphics Library for X-windows Dear Collegues, I am making scientific simulations and need some simple graphics library for display of the results in X-windows system. The subroutines should be higher-level in comparison with Xlib and Motif and be able to: 1. Open a window for graphics (probably using Motif). 2. Plot in the window a pixel, line, and filled polygon in an arbitrary color. 3. (Optional) Plot an axis. I shall be grateful, if somebody knows any place where to find such a shareware. Yours, Alexander Puhov, E-mail: jxm1@ipp-garching.mpg.de ------------------------------ From: Fred Hickernell Date: Tue, 19 Sep 1995 16:23:38 +0800 (EAT) Subject: Front-ends for Numerical Simulation Packages My MSc student is developing a graphical front-end for numerical simulations that is intended to be general in nature (that is, not application specific). This front-end will track the simulation so that the user can take corrective actions (modify parameters or terminate) as necessary. The simulation might be the solution of a large system of ODEs or PDEs, a large optimization problem, etc. The intended platform is UNIX. Is anyone aware of similar work that has been done and can point us to some references? Thanks, Fred Fred J.

The position is open in the framework of an ESPRIT contract in connection with European reseach centres and industrial partners. For this project we want someone with experience both in parallel computing and optimization techniques. Basically, we have to identify the most appropriate methods for solving optimization problems (arising in Multi Body Simulation) suitable for a implementation on a parallel platform. The type of target computer has to be selected according to the parallel features of the selected numerical techniques, it may be either shared memory multi-CPU workstation or network of computers. Once a technique and a platform have been selected, the implementation will have to be performed. Some issues related to parallel computing on a network of computers will also be addressed (fault-tolerance, load balancing, ...). The research to be developed in the framework of this contract is clearly industrially oriented. The position is in the Parallel Algorithm Project at CERFACS, where the main research activities are : - Large sparse matrix calculations: - direct linear solvers - iterative linear solvers, preconditioning - eigensolvers - Domain decomposition - Large scale nonlinear systems and optimization - Reliability of numerical software - Heterogeneous computing For detailed information about CERFACS URL address : http://www.cerfacs.fr/algor For more information about Toulouse, the city where CERFACS is located URL address : http://www.cict.fr/toulouse/EBienvenue.html Please send email to giraud@cerfacs.fr ------------------------------ From: Dwight Duffus Date: Mon, 18 Sep 1995 10:26:58 -0400 Subject: Position at Emory University NA POSITION MATHEMATICS AND COMPUTER SCIENCE DEPARTMENT EMORY UNIVERSITY, ATLANTA, GEORGIA, 30322 The Department of Mathematics and Computer Science, Emory University, invites applications for an anticipated tenure track Assistant Professorship or a tenured appointment, at the rank of Associate Professor or Professor, effective 1996-97.
