New Approaches to Distributed Middleware for Resource Sharing
Traditional distributed computing paradigms such as PVM and MPI(CH)
have had mixed success in shared-resource distributed computing
environments. We identify some fundamental issues in resource
sharing in multi-domain distributed systems, and argue that effective
sharing and aggregation in such environments is critically dependent
upon minimizing global state between providers, and between providers
and clients. The H2O framework has made one step in this direction, by
decoupling provider concerns from client requirements, and enabling
clients to (re)configure resources as required. H2O is based on
a "pluggable" software architecture to enable flexible and
reconfigurable distributed computing. A key feature is the provisioning
of customization capabilities that permit clients to tailor provider
resources as appropriate to the given application, without compromising
control or security. The system also supports dynamic environment
preconditioning to automate many of the tasks required in
multidomain resource sharing. The architecture and design philosophies
of these software frameworks, their implementation, recent experiences,
and planned enhancements are described, in the context of new paradigms
and directions for metacomputing middleware.
About the speaker:
Vaidy Sunderam is a professor of Computer Science at Emory
University. His research interests are in parallel and
distributed processing systems, high-performance message passing
software, and infrastructures for collaborative computing. His
prior and current research efforts have focused on system
architectures and implementations for network protocol middleware,
collaboration tools, and heterogeneous metacomputing, including
the PVM system and several other frameworks such as IceT, H2O,
and Harness. Professor Sunderam teaches computer science at the
beginning, advanced, and graduate levels, and advises graduate
theses in the area of computer systems.

Academic Research and Industry:
Does academic research meet the needs of industry today?
There are marked differences between academic research and that done by industrial companies.
Huge amounts of needed experience, background knowledge and the complexity of technical and
business problems plus the mutual dependencies between academia and industry require that
research programs be long term efforts. Most of today's research is funded by the EU and governments:
Using examples from aerospace and retail businesses, this presentation will try to answer these questions and will conclude by presenting an outlook on actual research topics with a forecast of those most needed by industry.
- Do governmental programs meet industry expectations?
- How are research programs developed and who is deciding on which projects will be sponsored and which will not?
- Do the results serve the commercial interests?
- Is academic research just a "low-cost" competitor for industrial research?
- How can a closer relationship between university research and industry be achieved?
About the speaker:
Jens Nicolaysen founded JNC in 1982 in Germany. Today 40 employees are active in the US and Europe for
software development for Web based solutions as well as Hosting solutions. Also development in new
technologies such as distributed computing and RFID technology is part of the core business.
In a second field JNC concentrates on project management for international projects together with risk
management, quality management and system selections. Clients are found in the fields of aerospace,
