As parallel computers become more common, scheduling strategies become important as a means of balancing the need for exclusive use of the machine's resources and the desire to make these resources readily available to many diverse users and applications. Moreover, this has to be done in an interactive setting while also coordinating the use of multiple non-CPU resources.

Continuing the tradition established at IPPS'95, the workshop is intended to attract people from academia, supercomputing centers and national laboratories and parallel computer vendors who will address resource management issues in multitasking parallel systems. The workshop will provide an opportunity to attempt to resolve conflicting goals such as short response times for interactive work, minimal interference with batch jobs, fairness to all users, and high system utilization. We hope to achieve a balance among various inputs including: reports on current practices covering the entire range of systems from large and heavily-used installations to the desktop; proposals for novel schemes that have not yet been tested in a real environment; and realistic models and analysis. The emphasis will be on practical designs in the context of real (parallel) operating systems.

Topics of interest include:
- Benchmarking and performance metrics to compare scheduling schemes
- Experience with scheduling policies on current systems
- Optimization of multiple-resource scheduling (e.g., memory too)
- Scheduling on SMPs, scalable SMP systems, and clusters
- Workload characterization and classification
- Fairness, priorities, and accounting issues
- Load estimation and load balancing
- Scheduling on heterogeneous nodes (e.g., with different amounts of memory)
- Support for different classes of jobs (e.g., interactive vs. batch)
- Time slicing and gang scheduling
- Effect of scheduling strategies on application performance
- Interaction of scheduling with memory management and I/O

Optical means are now widely used in telecommunication networks, and the evolution of optical and optoelectronic technologies tends to show that they could be successfully introduced in shorter distance interconnection systems such as parallel computers. These technologies offer a wide range of techniques that can be used in interconnection systems. But introducing optics in interconnect systems also means that specific problems have yet to be solved while some unique features of the technology must be taken into account in order to design optimal systems. Such problems and features include device characteristics, network topologies, packaging issues, compatibility with silicon processors, system level modeling.

The purpose of WOCS is two-fold. First, we hope to provide a good opportunity for the optical, architecture, and communication research communities to get together for a fruitful cross-fertilization and exchange of ideas. The goal is to bring the optical interconnects research into the mainstream research in parallel processing, while at the same time provide the parallel processing community with a more comprehensive understanding of the advantages and limitations of optics as applied to high-speed communications. In addition, we intend to assemble a group of major research contributors to the field of optical interconnects for assessing its current status, and identifying future directions.

WOCS will feature invited speakers, and several sessions of submitted papers. The presentations will cover the topics of:

- High-speed interconnections
- Optical interconnects
- Algorithms using optical interconnects
- Parallel optical architectures
- Reconfigurable optical interconnects and architectures
- Applications of optical interconnects
- Modeling of optical systems and applications
- Performance analysis and comparisons
- Packaging of optical interconnects
- System demonstrations
- Routing in optical networks

Efficient parallel solutions have been found to many problems. However, there still exists a large class of problems - known as irregularly structured problems - that lack efficient solutions and systems support. This workshop on solving irregularly structured problems in parallel aims at fostering the cooperation among practitioners and theoreticians of the field. It is the sixth in the series, after Geneva, Lyon, Santa Barbara, Paderborn, and Berkeley.

Irregular'99 will feature invited talks and several sessions of submitted papers. The presentations will cover the following topics: mesh and sparse matrix computations, approximation and combinatorial optimization, parallel languages and models, compiler optimization and runtime systems, load balancing and scheduling, performance prediction and simulation, Internet computing and data-intensive applications.

Workshop papers will be included in the IPPS/SPDP Workshop Proceedings published by Springer-Verlag as part of their Lecture Notes in Computer Science (LNCS) Series. Extended versions of workshop papers will be solicited for a special journal edition and authors will receive information before or during the workshop. Previous proceedings of Irregular series appeared as LNCS 980, 1117, 1253 and 1457.

Clusters composed of fast personal computers are becoming more and more attractive as cheap and efficient platforms for distributed and parallel applications. The main drawback of a standard NOW (Network Of Workstations) is the poor performance of the standard inter-process communication mechanisms based on RPC, sockets, TCP/IP, Ethernet. Such standard communication mechanisms perform poorly both in terms of throughput as well as message latency.

Recently, several prototypes developed around the world have proved that re-visiting the implementation of the communication layer of a standard operating system kernel, a low cost hardware platform composed of only commodity components, can scale up to several tens of processing nodes and deliver communication and computation performance exceeding the one delivered by the conventional high-cost parallel platforms.

Despite the importance of this break-through, that allows the use of inexpensive hardware platforms for efficient support of large/medium/fine grain parallel computation in a NOW environment, few papers describing their design and implementation still appear in the literature. Multiprogramming and co-scheduling of communicating processes so that "real applications" can be efficiently parallelized in NOW environments are still open research issues as well.

The PC-NOW workshop provides a forum where researchers and practitioners can discuss issues, results, and ideas related to the design of efficient NOWs based on commodity hardware and software components.

The program will consist of two keynote lectures - to be announced - and a number of contributed (25 minute) presentations including but not limited to:

- Experience with low-cost, high-performance NOW
- Low-cost communication hardware for personal computers
- Performance evaluation and benchmarks for NOW
- Porting of significant applications on low-cost NOW
- Efficient implementation of message passing libraries for NOW
- Parallel application environment for NOW
- Communication architectures
- Communication paradigms
- Industrial relevance

Invited Speakers:

There will be two invited speakers presenting state-of-the-art results in
the field as well as an overview of recent advances in the international
research community.

Ambuj Singh, Department of Computer Science, University of California at Santa Barbara, USA

Topics:

Formal methods have been widely investigated in academic institutions and more recently have been applied in industry. They allow systems and their properties to be described precisely using mathematical notation. Algorithmic solutions are developed from the formal specification with the help of mathematical techniques and tools. Although they may be expensive to apply, formal methods are the only way to ensure that an implementation is correct with respect to a specification, and are thus an important tool for the development of reliable systems. The objective of the workshop is to gather people, both from academia and industry, who use and/or develop formal methods for parallel programming. FMPPTA'99 will emphasize two steps related to formal methods: the modeling phase where the problem is stated formally, and the proving phase that demonstrates the correctness of an implementation. As this workshop is a part of IPPS/SPDP, authors are strongly invited to use real case studies borrowed from parallel processing or distributed computing.

Workshop 14: All Day Friday

WORKSHOP ON FAULT-TOLERANT PARALLEL AND DISTRIBUTED SYSTEMS

Workshop Chair:

D.R. Avresky, Boston University, USA

Increasingly large parallel and distributed computing systems provide unique challenges to the researchers in dependable computing, especially because of the high failure rates intrinsic to these systems. While commercial and scientific companies share the need for massive throughput and low latency, dependability of service is also a concern. In addition to providing uninterrupted service, commercial systems must be free from data corruption. Achieving dependability in highly scalable parallel and distributed systems poses a considerable challenge. As the number of components increases, so does the probability of a component failure. Therefore, improved fault-tolerant technology is required for highly scalable parallel and distributed systems.

The goal of this workshop is to provide a forum for researchers and practitioners to discuss issues related to fault-tolerant parallel and distributed systems. All aspects of design, theory and realization of dependable network-based computing systems are of interest.

Topics of interest include, but are not limited to:

- Dependable distributed systems
- Fault-tolerant protocols for distributed systems
- Fault-tolerance in clusters of workstations and PCs
- Fault-tolerant interconnection networks
- Fault-tolerant parallel programming
- Using COTS for designing dependable network based computing systems
- Portable checkpointing for heterogeneous distributed systems
- Fault injection in parallel and distributed systems
- Dependability evaluation and validation of fault-tolerant parallel and distributed systems

The last decade has seen an explosive growth in database technology and the amount of data collected. Advances in data collection, use of bar codes in commercial outlets, and the computerization of business transactions have flooded us with lots of data. We have an unprecedented opportunity to analyze this data to extract more intelligent and useful information. Data mining is the efficient supervised or unsupervised discovery of interesting, useful, and previously unknown patterns from this data. Due to the huge size of data and amount of computation involved in data mining, high-performance computing is an essential component for any successful large-scale data mining application. This workshop will provide a forum for presentation of recent results in high-performance computing for data mining including applications, algorithms, software, and systems. Works which address issues in high performance computing and/or memory hierarchy are of interest.

Topics of interest include:

- Classification and regression
- Decision trees
- Association rules
- Dependency derivation
- Clustering
- Deviation detection
- Similarity search
- Bayesian networks
- OLAP
- OLAM

8 AM - 12 NOON
Tutorial 3

ENGINEERING WEB-ENABLED SYSTEMS
Nikola Serbedzija
GMD FIRST, Berlin, Germany

Who Should Attend:

The tutorial is meant for system designers, teachers, researchers, practitioners, and advanced students who want to gain better understanding of the design and development of Web-enabled systems. It will demonstrate (1) how to enrich Web sites with distributed software, (2) how to enable the existing applications for the Web use, and (3) how to develop a multi-media Java-based user interface for Web applications. There will be several running illustrations of Web-enabled systems with media-rich user interface. The attendee should be familiar with the World Wide Web and related technologies. No specific technical expertise is required, since the focus will be on design issues and principles rather than implementation details.

Course Description:

A Web-enabled system is a distributed system that uses a Web browser as a front-end. The goal of the tutorial is to explain principles of Web-enabled systems and provide basic understanding of software concepts, techniques and architectures needed for integrating new or existing applications into a Web-based distributed framework. The tutorial addresses a number of issues related to Web enabling technology like client/server and message-passing paradigms, basic Web principles (HTTP server properties, protocols, CGI, JavaScripts, etc.), dynamic collaboration, code migration, Java's remote method invocation, and multi-tier middleware architectures. Each concept will be illustrated with concrete examples, gradually constructing a case study that shows how to implement a Web-enabled application.

Lecturer:

Nikola Serbedzija is a senior scientist at GMD FIRST (German National Research Center for Information Technology). His major research interest is the design of parallel and distributed systems for dedicated use in different application domains. He is the principal designer of the GoWeb system, an object-oriented middleware for enabling computing resources for use within the WWW. He has published numerous contributions in journals and proceedings on distributed and parallel systems, neurosimulations and Web-based computing. He has lectured at Technical University Berlin and has given a number of tutorials and special seminars. He received a Ph.D. in Computer Science from University of Belgrade in 1989. More information about the author and tutorial can be found at URL http://www.first.gmd.de/goweb/.
