Title: Dynamic Data Driven Applications Systems

Abstract:

This talk will discuss the capabilities, research challenges and
opportunities to enable Dynamic Data Driven Application Systems (DDDAS).
DDDAS entails the ability to incorporate additional data into an executing
application (these data can be archival or collected on-line), and reversely
applications will be able to dynamically steer the measurement process. Such
capabilities offer the promise of augmenting the analysis and prediction
capabilities of application simulations and the effectiveness of measurement
systems, with a potential major impact in many science and engineering
application areas. Enabling DDDAS requires advances in the application
modeling methods and interfaces, in algorithms tolerant to perturbations of
dynamic data injection and steering, and in systems software to support the
dynamic environments of concern here. Research and development of such
technologies requires synergistic multidisciplinary collaboration in the
applications, algorithms, software systems, and measurements systems areas,
and involving researchers in basic sciences, engineering, and computer
sciences. The talk will address specifics on such technology challenges, and
in particular in the systems software areas, and provide examples from NSF
funded projects.

Bio:

Dr. Darema is the Senior Science and Technology Advisor in ACIR and CISE,
and Director of the Next Generation Software (NGS) Program. Dr. Darema's
interests and technical contributions span the development of parallel
applications, parallel algorithms, programming models, environments, and
performance methods and tools for the design of applications and of software
for parallel and distributed systems. Dr. Darema received her BS degree from
the School of Physics and Mathematics of the University of Athens - Greece,
and MS and Ph. D. degrees in Theoretical Nuclear Physics from the Illinois
Institute of Technology and the University of California at Davis
Respectively, where she attended as a Fulbright Scholar and a Distinguished
Scholar. After Physics Research Associate positions at the University of
Pittsburgh and Brookhaven National Lab, she received an APS Industrial
Fellowship and became a Technical Staff Member in the Nuclear Sciences
Department at Schlumberger-Doll Research. Subsequently, in 1982, she joined
the IBM T. J. Watson Research Center as a Research Staff Member in the
Computer Sciences Department and later-on she established and became the
manager of a research group at IBM Research on parallel applications. While
at IBM she also served in the IBM Corporate Strategy Group examining and
helping set corporate-wide strategies. Dr. Darema was elected IEEE Fellow
for proposing in 1984 the SPMD (Single-Program-Multiple-Data) computational
model that has become the popular model for programming today's parallel and
distributed computers. Dr. Darema has been at NSF since 1994, where she has
developed initiatives for new software capabilities, a new paradigm for
applications (DDDAS), and pushing for research in the interface of
neurobiology and computing. The NGS, the BITS, and the Scalable Enterprise
Systems programs foster such ideas. She is also managing the Dynamic Data
Driven Application Systems (DDDAS; an ITR component). Also involved in the
Nanotechnolgy Science and Engineering, the Scalable Enterprise Systems, and
the Sensors programs (cross-Directorate programs). During 1996-1998 she
completed a two-year assignment at DARPA where she initiated a new thrust
for research on methods and technology for performance engineered systems.
