We will begin with an overview of software systems and tools that are available to support network-based computing, and will describe several production applications to demonstrate the effectiveness and viability of network computing. We will devote the remainder of the course to PVM and HeNCE -- software systems that enable concurrent computing on heterogeneous collections of multiprocessors, supercomputers, scalar machines, and workstations. PVM (Parallel Virtual Machine) is software infrastructure that allows heterogeneous groups of machines to be used as a general-purpose concurrent computing resource. We will focus on concurrent applications for PVM, using several models of parallelism. HeNCE (Heterogeneous Network Computing Environment) is a graphical toolkit and methodology that significantly eases the task of application development for PVM. HeNCE is based on the notion that concurrency can be expressed using a variant of directed acyclic graphs, where vertices represent computation and arcs represent data and control dependencies. We will describe HeNCE and illustrate its use in graphicly assembling concurrent applications from simple (sequential) building blocks. This tutorial is intended for people interested in loosely coupled concurrent computing. Application and systems developers in the areas of large-scale scientific computing, heterogeneous systems, and general purpose concurrent processing will benefit from the material covered in this course. The lectures assume a general knowledge of parallel processing and networking. The lecturers of the tutorial are Jack Dongarra, Al Geist and Bjarne Stig Andersen. Jack Dongarra is a professor at the University of Tennessee (Knoxville) and a computer scientist at the Oak Ridge National Laboratory. Al Geist is a computer scientist at the Oak Ridge National Laboratory. Bjarne Stig Andersen is a computer scientist at UNI*C (the Danish Computing Centre for Research and Education). The computer corporations Convex, Digital, Silicon Graphics and IBM are going to install cluster workstations for the PVM and HeNCE exercises and demonstrations. Tutorial on PVM and HeNCE is organised the day before the Workshop on Parallel Scientific Computing in Denmark.

GAMS is an on-line cross-index of mathematical and statistical software available for use by staff of the National Institute of Standards and Technology (NIST). Since some 9000 problem-solving software modules from nearly 80 packages are indexed, external users may find this information useful. GAMS also operates as a virtual software repository, providing distribution of abstracts, documentation, and source code of software modules that it catalogs; however, rather than operate a physical repository of its own, GAMS provides transparent access to multiple repositories operated by others. Currently four repositories are indexed, three within NIST, and netlib. Both public-domain and proprietary software are indexed. Although source code of proprietary software is not redistributed by GAMS, documentation and example programs often are. The primary indexing mechanism is a tree-structured taxonomy of mathematical and statistical problems developed by the GAMS project. Access to GAMS is available in a variety of ways. o Local clients Two user interfaces to the GAMS system are available : gams, a simple command-line interface, and xgams a graphical user interface based on the X11 window system. These programs run on your local workstation, connecting (via TCP/IP socket-based communication) to the GAMS server on gams.nist.gov to obtain user requested information. Source and binary distributions of the clients for Unix workstations can be obtained by anonymous FTP from enh.nist.gov in the directory [.gams]. (Transfer the file README first for further instructions.) o Anonymous logins The GAMS clients described above can be tried out using public-access accounts at NIST. To do this, telnet to gams.nist.gov, specifying the username gams for the command-line interface, or xgams for the X11 graphical user interface. Only a limited number of simultaneous logins are permitted. o World Wide Web (Mosaic) An HTTP-GAMS gateway providing access to most GAMS facilities for users of the World Wide Web is also available. This can be accessed using most WWW browsers, including Mosaic. To do so, open the URL http://gams.nist.gov. o Gopher A gopher gateway to the anonymous GAMS logins is also provided. To access this, connect to the default gopher server on gams.nist.gov. For more information, contact Ron Boisvert (boisvert@nist.gov). ------------------------------ From: Someone at Berkeley Date: Fri, 11 Mar 1994 10:59:12 -0800 Subject: Bay Area NA Day at Berkeley BAY AREA NUMERICAL ANALYSIS DAY Saturday, March 26, 1994 University of California at Berkeley Physical Sciences Lecture Hall (PSL) Gayley Road at University Drive Come and meet colleagues and students from all over the Bay Area!

The ideal candidate would have a strong interest in both developing innovative models for current design activities, and studying and developing technology for the modeling process itself. Areas of interest may include computational mathematics, new modeling paradigms, including declarative and/or object-oriented modeling environments, geometric representation and reasoning, abstraction and approximation methods, and multi-level, mixed-mode simulation. Candidates should have an M.S. or Ph.D. in Mechanical Engineering, Physics, Computer Science, or related discipline and a very strong research and/or development record in simulation and numerical methods. Development and delivery of innovative applications and publication of research results at the international level are both encouraged. Our group investigates the practice and technology of modeling, simulation and design for research, technology, and product development programs. We work with the participants to develop new processes and computational tools in order to foster increased concurrency, information reuse, and more effective and widespread analytical engineering methods. This requires a multi-disciplinary collection of highly talented and motivated individuals with backgrounds drawn from computer science, engineering, physics, and applied mathematics. The positions offer exciting challenges, wide variety, and the potential to have a significant impact.
