**Subject: A Shell Program to Search the CML Directory**

The enclosed "ams" is a simple shell program to search the CML directory. I

call this "ams" but any user can rename it either "cml" or "siam" or "maa" or

whatever other mathematical organization lies closer to her heart.

Unfortunately, during peak hours e-math.ams.com slows down so please try to

use it during quieter times. Enjoy...Paul

P.S. Please note that a less convenient "siamdb" is (or used to be) available

Tutorial on PVM and HeNCE: Tools for Heterogeneous Network Computing

June 20, 1994 @ UNI*C, DTH, 2800 Lyngby, Denmark

This tutorial will cover methodologies and strategies for

concurrent computing on heterogeneous networks of independent

computer systems. 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.

**Subject: Guide to Available Mathematical Software**

The NIST Guide to Available Mathematical Software (GAMS) is now

available for public use on the Internet on an experimental basis.

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.

**Subject: Positions at Xerox**

Design Practice, Mathematical Modeling and Scientific Computation

The Xerox Modeling Research & Technology area is seeking several

outstanding individuals with proven research and development records in

the practice and technology of mathematical modeling and scientific

computation for electro-mechanical design. 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. To apply, send resume and any additional

information (e.g., publications) to:
