Crow Date: Wed, 8 Feb 1995 16:03:42 +0600 Subject: Eigenvalue Problems for Tridiagonal Systems I would like to hear what currently are believed to be ``methods-of-choice'' for dealing with eigenvalue problems for complex, tridiagonal systems. No symmetry is assumed, and in particular, the matrix is *not* Hermitian. The problem I have at hand requires only the eigenvalues, not the associated eigenvectors. I'd be obliged for any helpful ideas or pointers to related work. - John John A.

Candidates should have a Ph.D. in computer science or a related discipline and comprehensive knowledge in at least one of the following areas: compiler design, optimizing compilers, software tools, software design, or performance evaluation. A good knowledge of computer architecture and computer systems is highly desirable. The successful candidate will participate in the development of algorithms and software tools for the automatic differentiation of large-scale computer codes. This project is interdisciplinary in nature and interfaces with efforts in numerical optimization and parallel computing. Information on the Computational Differentiation Project can be found in http://www.mcs.anl.gov/Projects/autodiff/index.html. The Mathematics and Computer Science Division supports an excellent computational environment that includes access to high-performance scientific workstations, a scientific visualization and virtually reality laboratory, and state-of-the-art parallel computers. Argonne is located in the southwestern Chicago suburbs, offering the advantages of affordable housing and good schools, as well as easy access to the cultural attractions of the city. Applicants must have received their Ph.D. not more than three years prior to the beginning of the appointment. The appointment is available immediately and for a one-year term (renewable). Applications should be addressed to Walter McFall, Box mcs-postdoc6, Employment and Placement, Argonne National Laboratory, 9700 S. Cass Avenue, Argonne, IL 60439, and must include a resume and the names and addresses of three references. For additional information, contact Chris Bischof (bischof@mcs.anl.gov). Argonne is an affirmative action/equal opportunity employer. ------------------------------ From: Antonio Messina Date: Mon, 6 Feb 1995 16:30:06 +0100 Subject: Postdoctoral Fellowship in Bologna, Italy Postdoctoral Research Fellowships Numerical Magnetohydrodynamics The EEC ``Human Capital and Mobility'' program has established a numerical MHD grant, which will finance one-year fellowships in the group detailed below. The grant supports collaborations in the following principal areas: MHD Flows and Turbulence Dynamos Thermal Convection Interstellar Medium; Stellar Winds; Solar Wind and Corona Numerical Techniques for MHD The fellowships are intended for citizens of the member states of the European Community (Belgium, Denmark, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, United Kingdom) and associated states (Austria, Iceland, Finland, Norway and Sweden). The salary and associated research costs will be at the standard rate of each state. Candidates may not apply in their own country; they should write directly to the group providing their curriculum vitae, a list of recent publications, two letters of recommendation and a statement of research interests. For the year 1995-6, the deadline for receipt of applications is March 1st 1995.

Gilbert Date: Fri, 10 Feb 1995 11:28:10 PST Subject: Postdoctoral Position at Xerox PARC The Theoretical Computer Science and Computational Methods Area of the Xerox Palo Alto Research Center is recruiting for a postdoctoral position in algorithms for the 1995-1996 academic year. The theory group at PARC is part of the larger Computer Science Laboratory, well known for over twenty years of influential basic research in computer systems. The theory group itself specializes in theory inspired by practical problems arising in graphics, physical simulation and modeling, and information retrieval. Ongoing research includes work in triangulation and mesh generation, approximate searching, graph algorithms, partitioning and layout for parallel computation, sparse matrix algorithms, and approximation algorithms. The unifying theme of our work is its emphasis on algorithms that find provably good solutions to hard problems arising in practice. The postdoc will be expected to interact closely with the regular area members, but will also be free to pursue his or her own research interests. To apply please submit: a resume; a summary of research interests; and reprints of publications based on thesis and other research. Applicants are also responsible for requesting that three or more letters of reference be sent directly to us. To be assured of full consideration, all material including reference letters must arrive by March 17, 1995. Direct all material to: John R. Gilbert Xerox Palo Alto Research Center 3333 Coyote Hill Road Palo Alto, CA 94304 gilbert@parc.xerox.com fax: 415-812-4471 Applications by email will be accepted. Applications will be acknowledged, by email if possible, and each applicant will be notified individually as soon as a decision has been reached on the application. ------------------------------ End of NA Digest ************************** -------
