Abstract:
Scientific workflows have become an enabler of complex scientific analyses.
They provide a representation of analyses composed of heterogeneous models designed by groups of scientists. At the same time workflows have also become a useful representation that is used to manage the execution of large-scale computations. Although workflow systems are able to facilitate the automated generation of data products, many issues still remain to be solved. These issues exist in different forms in the workflow lifecycle. During workflow creation appropriate input data need to be discovered. During workflow mapping and execution data need to be staged in and staged-out of the computational resources. As data are produced, they need to be archived with enough metadata and provenance information so that they can be interpreted and shared among collaborators. This talk will describe the workflow lifecycle and discuss the issues related to data management at each step. Examples of challenge
problems will be given in the context of the astronomy, earthquake science, gravitational-wave physics, and other scientific applications.
These computations, represented as workflows, are running on today's national cyberinfrastructure such as the Open Science Grid and the TeraGrid and use workflow technologies such as Pegasus and DAGMan to map
high-level workflow descriptions on to the available resources and execute the resulting computations. The talk will describe the challenges, possible solutions, and open issues faced when mapping and executing the
large-scale workflows on the current cyberinfrastructure.
Particular emphasis will be given to issues related to the management of data throughout the workflow lifecycle.
Curiculum Vitae:
Ewa Deelman is an Assistant Research Professor at the USC Computer Science Department and a Project Leader at the USC Information Sciences Institute. Dr. Deelman's research interests include the design and exploration of
collaborative scientific environments based on Grid technologies, with particular emphasis on workflow management as well as the management of large amounts of data and metadata. At ISI, Dr. Deelman is leading the Pegasus project, which designs and implements workflow mapping techniques for large-scale workflows running in distributed environments. Dr. Deelman received her PhD from Rensselaer Polytechnic Institute in Computer Science in 1997 in the area of parallel discrete event simulation.
II)
S-Cube - A Network of Excellence on Software Services and Systems
 |
Christos N. Nikolaou |
Abstract:
The Software Services and Systems Network (S-Cube) will establish a unified, multidisciplinary, vibrant research community which will enable Europe to lead the software-services revolution, helping shape the software-service based Internet which is the backbone of our future interactive society.
By integrating diverse research communities, S-Cube intends to achieve world-wide scientific excellence in a field that is critical for European competitiveness. S-Cube will accomplish its aims by meeting the following objectives:
- Re-aligning, re-shaping and integrating research agendas of key
European players from diverse research areas and by synthesizing and
integrating diversified knowledge, thereby establishing a long-lasting
foundation for steering research and for achieving innovation at the
highest level.
- Inaugurating a Europe-wide common program of education and training for
researchers and industry thereby creating a common culture that will
have a profound impact on the future of the field.
- Establishing a pro-active mobility plan to enable cross-fertilisation
and thereby fostering the integration of research communities and the
establishment of a common software services research culture.
- Establishing trust relationships with industry via European Technology
Platforms (specifically NESSI) to achieve a catalytic effect in shaping
European research, strengthening industrial competitiveness and
addressing main societal challenges.
- Defining a broader research vision and perspective that will shape the
software-service based Internet of the future and will accelerate
economic growth and improve the living conditions of European citizens.

Data and Information Searching over Distributed Infrastructures
 |
Yannis Ioannidis
|
Abstract:
Large-scale distributed search over emerging Grid-based and other infrastructures faces several challenges, some of which may be considered obvious, e.g., the latency, heterogeneity, and dynamicity of the underlying distributed environment, while others may be unexpected, e.g., the need for optimizing the search based on nontraditional
criteria, such as the freshness or completeness of the search results, or the need to customize the overall search behavior to personal characteristics of the individual users. In this talk, we identify and analyze some of the challenges that we believe are particularly important and exciting, and discuss possible approaches that may lead to their solution. We draw upon our experience from several past and current European Projects (BRICKS, DELOS, DILIGENT, DRIVER, DRIVER II,
D4SCIENCE, HEALTH-E-CHILD) as well as our independent work on "Open Agoras of Data and Information" at the University of Athens.
