Title: Models and Architectures for Effective Deployment of Large-
Scale Simulations across Parallel and Distributed Platforms

Abstract:
In order to effectively deploy large-scale simulations across
distributed resources, it is vital that formal design models be
developed for design and performance prediction. Currently, many
large-scale simulations are being deployed across clusters of
machines. Clusters fall into two broad categorizations: homogeneous
and heterogeneous. In homogeneous clusters, resources are basically
identical. For heterogeneous, resources can have great variations in
structure and speciality. In this talk, we will focus on homogeneous
clusters, and on hierarchical clusters, a type of heterogeneous
cluster. We will present and/or introduce various general design
models and architectures. We will show that our models are realistic
and have wide-utility in a variety of arenas: as design models,
performance models, and complexity models. Moreover, our models have
been validated on a number of applications across a number of
engineering and computational science applications, including spin
system simulations (for example for quantum chromodynamics), network-
centric operations, protein folding, numerical linear algebra (for
example large-scale system solvers), tissue simulation (for example
tumor growth), information retrieval, and social network analyses.



Bio:

Eunice E. Santos has B.S. and M.S. degrees in both Mathematics and
Computer Science, and received a PhD in 1995 from the University of
California, Berkeley in Computer Science. From 1995-2000, Dr. Santos
was a faculty member in the Department of Electrical Engineering and
Computer Science at Lehigh University. Since 2000, Dr. Santos is the
Director of the Laboratory for Computation,  Information &
Distributed Processing, and an Associate Professor in the Department
of Computer Science and in the Genetics, Bioinformatics and
Computational Biology Program at Virginia Polytechnic Institute &
State University. Dr. Santos has been awarded an NSF CAREER grant,
the Spira Award for Excellence in Teaching, and the Robinson Faculty
Award. She is also currently named to the Top Ten Teacher's List in
the College of Engineering at Virginia Tech. She was recently program
chair for IDPT'06 and is on a number of program committees. She is on
the editorial board of Scientific Programming, and subject area
editor for the Journal of Supercomputing. She is currently a member
of the DARPA/IDA Defense Science Study Group.
