<h1><font size="4" face="Times New Roman"><b>Abstract</b></font></h1>
<br>
<p><font size="3" face="Times New Roman">Modern distributed computing
installations typically consist of large numbers of interconnected autonomous
workstations. The spectrum of coupling ranges from switch-interconnected
computing clusters to loosely coupled GRID-like systems (over the Internet),
and includes organizational installations where fast (say Infiniband,
Gigabit Ethernet or Optical) Local Area Networks are used. We consider
the problem of federating resources over this spectrum to effectively
provide some degree of concurrent processing to speed up specific tasks.
In addition to decomposition and deployment, the degree of coupling
imposes different constraints and challenges on the management of the
available networked resources. To alleviate the burden imposed by the
distributed resource management tasks, novel ideas are proposed for
the effective use and management of resources over the network fabric:
Intelligent Networks, Virtualization at the Process and Device levels,
and Adaptability in Heterogeneous systems are introduced. </font> <br>
</p>
<p><font size="3" face="Times New Roman">In the case of very tightly
coupled switch-interconnected clusters, Service Address Routing (SAR)
emerges as the solution of choice. It uses a novel paradigm where computing
nodes call services by name, in a location independent manner, rather
than by network address. An application would be oblivious to where
services are rendered and the intelligent network finds and routes service
requests to nodes registering as servers.</font> <br></p>
<p><font size="3" face="Times New Roman">For fast LANs, Process Level
Remote Execution and Device Virtualization were developed as environments
to harness the power of nodes participating in a cluster-set, also known
as a LAN computer federation. In addition to dedicated computers participating
in the federation, these paradigms allow lightly loaded nodes to contribute
available resources to the overall computational power of the resulting
federated system.</font> <br></p>
<p><font size="3" face="Times New Roman">In the case of heterogeneous
systems, the problem of node/device selection based on workload requirements
is presented together with an adaptability mechanism that allows changing
the workload requirements based on resource availability.</font></p>

Biography </b></font></h3>
<br>
<p><font size="3" face="Times New Roman">Professor Isaac D. Scherson
is currently stationed in Santiago (Chile) as Study Center Director
of the Education Abroad Program of the University of California. He
continues his research activity with Yahoo! Chile at the University
of Chile�s Department of Computer Science.</font> <br></p>
<p><font size="3" face="Times New Roman">Isaac D. Scherson is Professor
in the Department of Computer Science (The Bren School of Information
and Computer Sciences) and the Department of Electrical Engineering
and Computer Science (The Henry Samueli School of Engineering) at the
University of California, Irvine. He received BSEE and MSEE degrees
from the National University of Mexico (UNAM) and a Ph.D. in Computer
Science from the Dept. of Applied Mathematics of the Weizmann Institute
of Science, Rehovot, Israel. He held faculty positions in the Dept.
of Electrical and Computer Engineering of the University of California
at Santa Barbara (1983-1987), and in the Dept. of Electrical Engineering
at Princeton University (1987-1991). He is a Senior Member of the IEEE
Computer Society and a member of the ACM. Dr. Scherson has contributed
to numerous professional workshops and conferences as chair, co-chair
and/or member of the Technical Program Committee. Since 1992, he also
serves as a member of the IEEE Technical Committee on Computer Architecture
(TCCA), the IEEE Technical Committee on Parallel Processing (TCPP) and
as Associate Editor for IEEE Computer Architecture Letters and The Journal
of Interconnection Networks. Dr. Scherson was Visiting Scientist/Professor
at the University of Paris VI (Pierre et Marie Curie, 1997-2004), Visiting
Scientist/Professor at the University of Lille 1 (Lille, France, 2003),
Visiting Scientist with the INRIA (Rennes, France, 2004), Conseiller
Scientifique to France Telecom Research and Development (Paris, France.
2005-2009), distinguished guest lecturer at Ulm University (Germany,
2005), in addition to giving numerous Invited Distinguished Lectures
in academic and research institutions in various countries such as Germany,
France, Romania, Poland, Mexico, Brazil, Argentina, and Chile.</font> <br>
</p>
<p><font size="3" face="Times New Roman">His research interests include
concurrent computing systems, web server parallel architectures, interconnection
networks for embedded and cluster systems, resource management in embedded
and cluster systems, operating systems for concurrent computers, massively
parallel computer architectures, switching and permutation networks,
computer graphics, algorithms and their complexity and VLSI. His research
has been sponsored/funded by the Jet Propulsion Laboratory (JPL), NASA,
the NSF, the AFOSR, the state of California MICRO program and other
industrial sources.</font></p>
