===============================================================================

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.  For example, see

www.pads07.org/asym/asym07-refs.htm .

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.

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 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 include:

 * 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 online in PDF format.  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.
