Berry Date: Tue, 13 Jul 1993 21:20:06 -0400 Subject: XNetlib and Performance Database Server Announcing the release of XNetlib ver. 3.4 What it is - Xnetlib is a new version of netlib recently developed at the University of Tennessee and Oak Ridge National Laboratory. Unlike netlib, which uses electronic mail to process requests for software, xnetlib uses an X Window graphical user interface and a socket-based connection between the user's machine and the xnetlib server machine to process software requests. Xnetlib is available to anyone who has access to the TCP/IP Internet. Xnetlib provides access to files and a whois style database residing on the Netlib server at the Oak Ridge National Laboratory. Xnetlib also connects to two other xnetlib servers, one at Rice University, and the other at the Army Research Laboratory. Our intention is to release the xnetlib server code in a few months. New to this release is the Performance Database Server (described more fully below) and a conference database. Xnetlib requires the Athena widget set (Xaw), however, precompiled executables are available. How to get it - By anonymous ftp from netlib2.cs.utk.edu in xnetlib/xnetlib3.4.shar.Z By email, send a message to netlib@ornl.gov containing the line: send xnetlib3.4.shar from xnetlib Precompiled executables for various platforms are also available. For information get the index file for the xnetlib library: via anonymous ftp from netlib2.cs.utk.edu get xnetlib/index via email send a message to netlib@ornl.gov containing the line: send index from xnetlib If you have any questions, please send mail to xnetlib@cs.utk.edu PDS: A Performance Database Server The process of gathering, archiving, and distributing computer benchmark data is a cumbersome task usually performed by computer users and vendors with little coordination. Most important, there is no publicly-available central depository of performance data for all ranges of machines from personal computers to supercomputers. This Xnetlib release contains an Internet-accessible performance database server (PDS) which can be used to extract current benchmark data and literature. The current PDS provides an on-line catalog of the following public-domain computer benchmarks: Linpack Benchmark, Parallel Linpack Benchmark, Bonnie Benchmark, FLOPS Benchmark, Peak Performance (part of Linpack Benchmark), Fhourstones and Dhrystones, Hanoi Benchmark, Heapsort Benchmark, Nsieve Benchmark, Math Benchmark, Perfect Benchmarks, and Genesis Benchmarks. Rank-ordered lists of machines per benchmark available as well as relevant papers and bibiliographies. A browse facility allows the user to extract a variety of machine/benchmark combinations, and a search feature permits specific queries into the performance database. PDS does not reformat or present the benchmark data in any way that conflicts with the original methodology of any particular benchmark; it is thereby devoid of any subjective interpretations of machine performance. PDS is invoked by selecting the "Performance" button in the Xnetlib Menu Options. Questions and comments for PDS should be mailed to "utpds@cs.utk.edu." ------------------------------ From: Daniel B. Szyld Date: Fri, 16 Jul 93 15:42:59 EDT Subject: Congress Hearings on the Future of the Internet As many of you may know there is a push to privatize the Internet and charge per connect time and/or per bit transmitted. Congress has scheduled hearings on the subject. If you have an opinion on the subject, the following message might be of interest: From: Ted Baker Subject: on-line congressional hearing on internet This is an abbreviation of a longer message I received. I think all internet users should probably drop our Congress a line. --Ted Baker On July 26 at 9:30AM EDT, the Subcommittee on Telecommunications and Finance of the U.S. House of Representatives will hold the first Congressional Hearing ever held over a computer network.... One of the primary points that we are hoping to demonstrate is the diversity and size of the Internet. We have therefore established an electronic mail address by which people on the Internet can communicate with the Subcommittee before and during the hearing: congress@town.hall.org We encourage you to send your comments on what the role of government should be in the information age to this address. Your comments to this address will be made part of the public record of the hearing. Feel free to carry on a dialogue with others on a mailing list, cc'ing the e-mail address. Your cards and letters to congress@town.hall.org will help demonstrate that there are people who use the Internet as part of their personal and professional lives. We encourage you to send comments on the role of government in cyberspace, on what role cyberspace should play in government (e.g., whether government data be made available on the Internet), on how the Internet should be built and financed, on how you use the Internet, and on any other topic you feel is appropriate. This is your chance to show the U.S. Congress that there is a constituency that cares about this global infrastructure. If you would like to communicate with a human being about the hearing, you may send your comments and questions to: hearing-info@town.hall.org ------------------------------ From: Piero Morasso Date: Mon, 12 Jul 93 16:52:41 MET DST Subject: Conference on Articifical Neural Networks EUROPEAN NEURAL NETWORK SOCIETY C A L L F O R P A P E R S I C A N N ' 94 - SORRENTO ICANN'94 (INTERNATIONAL CONFERENCE ON ARTIFICIAL NEURAL NETWORKS) is the fourth Annual Conference of ENNS and it comes after ICANN'91(Helsinki), ICANN'92 (Brighton), ICANN'93 (Amsterdam).

These methods do not seem to be widely known and the software based on these methods are not readily available to control theorists, applied mathematicians and the practising engineers. The researchers and practising engineers working in these important applications areas will be exposed to these numerically reliable algorithms and the associated softwares through this course. Who Should Attend Mathematicians; computer scientists; and control, systems, and signal and image processing engineers. Practising engineers, graduate students and researchers looking for some future exciting areas of research are especially encouraged to attend. Recommended Background A first course in linear and numerical linear algebra and some basic knowledge in control and systems theory and/or signal and image processing. No rigorous knowledge of control theory and signal processing will be assumed. Instructors George Cybenko, Dartmouth College Biswa Nath Datta, Northern Illinois University Alan J. Laub, University of California, Santa Barbara. Robert J. Plemmons, Wake Forest University Paul Van Dooren, University of Illinois, Urbana-Champaign. The course will be divided into two parts. Part I -- Numerical Methods in Control and Systems Theory will be taught by Biswa Datta, Alan Laub, and Paul Van Dooren . Part II -- Numerical Methods in Signal and Image Processing will be taught by George Cybenko and Robert Plemmons. Attendees are advised to pre-register for the tutorial. On-site registration cannot be guaranteed. Notes of the lecture materials will be distributed upon check-in at the SIAM registration desk. ------------------------------ From: David Walker Date: Fri, 16 Jul 1993 20:02:47 -0400 Subject: Scalable High Performance Computing Conference CALL FOR PAPERS THE 1994 SCALABLE HIGH PERFORMANCE COMPUTING CONFERENCE SHPCC94 KNOXVILLE, TENNESSEE, U.S.A., MAY 23 - 25, 1994 GENERAL CHAIR: Jack Dongarra University of Tennessee and Oak Ridge National Laboratory Department of Computer Science 107 Ayres Hall Knoxville, TN 37996-1301 615 974-8295 (office) 615 974-8296 (fax) dongarra@cs.utk.edu PROGRAM CHAIR: David W.
