Symposium on Asynchronous Methods in Scientific and Mathematical Computing

ASYM'07

Organized as part of IEEE/ACM/SCS PADS'07 and ACM FCRC'07

June 12-15, 2007
San Diego, California, USA

Overview

Of late, a variety of research efforts have been focusing on approaches that broadly fall under the classification of asynchronous methods. Asynchronous methods evolve the states of different parts of a system at largely independent, dynamically staggered time instants. Asynchrony of updates arises from various reasons, such as from the underlying multi-scale phenomena, or the choice of multi-scale models, or the dynamic nature of the system, or simply due to the use of relaxed update schemes. The range of efforts in asynchronous methods is illustrated in this annotated bibliography of selected references.

Asynchronous methods are being motivated by reasons such as increasing the speed of sequential computation, for improving parallelism or decreasing the amount of computation and communication in a distributed computation setting, or for use as a more natural modeling paradigm. The applications of these methods span a wide range, such as molecular dynamics and plasma physics simulations, numerical integration schemes, and relaxation schemes for parallel execution.

This symposium is aimed at bringing the range of research in asynchronous methods together for cross-fertilization and facilitating the formulation of the underlying common theories and methods. It is also intended to bring together the diverse research community that is discovering this emergence of new asynchronous-time methods largely independently.

Scope

Of interest are approaches, methods, prototypes, experiences and viewpoints on the use of asynchronous-time (discrete event) approaches in scientific simulations and mathematical solvers. Papers are solicited that lend new light on underlying theory and implementation, or address issues such as accuracy, stability, speed of computation, flux conservation, parallel execution, speed vs. accuracy tradeoffs, fundamental limits of asynchronous evaluation, classification of asynchronously computable functions and so on.

Example topics of interest include:

• Fundamental concepts of asynchronous updates to different parts of system state
• Physical system modeling with discrete event simulation (DES) approaches
• Multi-scale system modeling and simulation with asynchronous methods
• DES-based simulation of highly dynamic and/or heterogeneous systems

Algorithms, formal methods, analysis systems, frameworks, case studies, literature surveys, and performance analysis studies are all relevant to this symposium. Both sequential as well as parallel execution are within scope.

Example application domains are:

• Molecular dynamics
• Biological simulations
• Fluid dynamics
• Material simulations
• Plasma simulations
• Other physical system simulations.

Relevant topics in mathematical computing aspects include:

• Asynchronous integration methods
• DES-based ODE/PDE solution methods
• Asynchronous simulation of dynamical systems
• Continuous-discrete hybrid simulation.

These application areas and topics are meant to be illustrative and are not exhaustive.

Submissions

Manuscripts must be submitted electronically in PDF format via www.pads07.org/asym/conf. Hard copy submission may be accommodated under exceptional cases (please contact the program chair).

Manuscripts must be unpublished and must not be under active consideration for publication elsewhere. Each submission must be include: a short abstract, a complete list of authors and their affiliations, a contact person for correspondence, postal and email addresses. Papers must be written in English and should not exceed 10 pages using IEEE Proceedings Formatting Guidelines (IEEE style files available for Word and LaTeX). Final versions of accepted papers would be limited to 8 pages, with option to buy additional pages.

Review

All submissions will be reviewed using a double-blind review process, i.e., the identity of authors, and referees will not be revealed to each other.

To ensure blind reviewing, authors' names and affiliations should not appear in the manuscript body, and first-person references to bibliographic entries should be suitably modified.

Publication

Accepted papers will appear in the proceedings of the IEEE/ACM/SCS PADS 2007. Selected articles from PADS 2007 will be considered for extension and publication within a Special Issue of SCS SIMULATION journal.

Important Dates

Manuscripts Abstracts of papers must be submitted no later than March 8, 2007. The submission system assigns paper identifiers, which can be used to upload manuscripts no later than March 10, 2007. Notification of committee recommendations will be made by March 15, 2007. Camera ready copies of accepted manuscripts must be submitted by April 1, 2007.
