Paper_Title: Evaluation of Scheduling Structures

Paper_Authors: Volker Hamscher and Uwe Schwiegelshohn and Achim
Streit and Ramin Yahyapour

Paper_Keywords: parallel job scheduling metacomputing distributed

Paper_Abstract: In this paper, we discuss typical scheduling structures
that occur
in metasystems or computational grids. Scheduling algorithms and
strategies applicable to these structures are introduced and classified.
To compare those different approaches simulations haven
been executed for different workload and machine configurations.
We point out some of the results for the performance of the schedulers
in the presented metasystem structures.

Paper_Title: An Architectural Meta-Application Model for Coarse
Grained Metacomputing

Paper_Authors: Stephan Kindermann and Torsten Fink

Paper_Keywords: programming model, metacomputing, formal languages,
architecture description language,model checking

Paper_Abstract: The emerging infrastructures supporting transparent use of
heterogeneous distributed resources enable the design of
a new class of applications. These meta-applications
are composed of distributed software components.
In this paper we describe a new model for component based meta-application
design based on a formal architectural description of the gross organization
of an application. This structural description is enriched by a formal
process algebraic characterization of component behavior.
Using this behavioral model we can formally check meta-applications
in an early development phase.
We present simple architectural styles
developed to support data-flow and control-flow driven
meta-application design on top of the Amica metacomputing
infrastructure.

Paper_Title: Reduced to the MAX - A Simplified Resource-Management
System for large Workstation-Pools

Paper_Authors: Achim Streit

Paper_Keywords: resource-management, concept, scheduling, workstation-pool

Paper_Abstract: In this paper, we present a concept for a lean
resource-management
system used in heterogeneous pools of workstations. A reduced infrastructure
in
combination with improved scheduling concepts leads to an easy-to-use,
highly-available, fast and effective system. This is achieved by
using a simplified architecture and new scheduling algorithms,
mapping the monitored information-data to mathematical functions
and merging existing technologies in one product.

Paper_Title: Javelin 2.0: Java-Based Parallel Computing on the Internet

Paper_Authors: Michael O. Neary and Alan Phipps and Steven Richman
and Peter Cappello

Paper_Keywords: Internet computing, scalability, fault tolerance,
branch-and-bound, Java

Paper_Abstract: Javelin is a Java-based infrastructure for parallel
Internet computing.
This paper presents Javelin 2.0, focusing on the enhancements that distinguish
it from prior versions of Javelin.
With regard to architecture, the paper presents
enhancements that facilitate aggregating larger sets of host processors.
The paper then presents: a branch-and-bound computational model,
the supporting Javelin 2.0 architecture,
a scalable task scheduler using distributed work-stealing,
a distributed eager scheduler, implementing fault tolerance,
and
the results of performance experiments.
Taken as a whole, Javelin 2.0 frees application developers
from concerns about complex interprocessor communication and fault tolerance
among Internetworked hosts.
When all or part of their application can be cast as a piecework or
a branch-and-bound computation,
Javelin 2.0 allows developers to focus on the underlying application
without sacrificing performance.

Paper_Title: Request Sequencing: Optimizing Communication for the Grid

Paper_Authors: Dorian Arnold and Dieter Bachmann and Jack Dongarra

Paper_Keywords: metacomputing, distributed heterogeneous computing,
scheduling, request sequencing, NetSolve

Paper_Abstract: As we research to make the use of Computational Grids seamless,
the allocation of resources in these dynamic environments
is proving to be very unwieldy. In this paper, we introduce,
describe and evaluate a technique we call request sequencing.
Request sequencing groups together requests for Grid services
to exploit some common characteristics of these requests
and minimize network traffic.
The purpose of this work is to develop and validate this
approach. We show how request sequencing can affect
scheduling policies and enable more expedient resource
allocation methods.

Paper_Title: Data distribution for Parallel CORBA Objects

Paper_Authors: Tsunehiko Kamachi and Thierry Priol and Christophe René

Paper_Keywords: Metacomputing, Grid, CORBA, PSE

Paper_Abstract: The design of application for Computational Grids
relies partly on communication paradigms. In most of the Grid experiments,
message-passing has been the main paradigm either to let several
processes from a single parallel application to exchange data or
to allow several applications to communicate between each others.
In this article, we advocate the use of a modern approach for
programming a Grid. It is based on the use of distributed objects,
namely parallel CORBA objects. We focus our attention on the handling
of distributed data within parallel CORBA objects. We show some
performance results that were obtained using a NEC Cenju-4 parallel
machine connected to a PC cluster.
