Mimetic Discretizations And What They Can Do For You
Recent advances in compatible discretizations enabled impressive gains in
computational science and affirmed the key role of homological principles
in numerical PDEs. Thanks to homological ideas and tools, we now have a
much better understanding of why some discretization methods work so well
and why other methods fail spectacularly. More importantly, homological
ideas can be used to develop stable and physically consistent
discretizations, such as mimetic methods, which replace PDEs by algebraic
equations that inherit their fundamental structural properties.
We provide a common framework for mimetic methods using algebraic topology
to guide our analysis. The key concept in our approach is the natural
inner product on co-chains. This inner product is sufficient to generate a
combinatorial Hodge theory on co-chains but avoids complications attendant
in the construction of robust discrete Hodge-star operators. In
particular, using a reduction and a reconstruction maps between
differential forms and co-chains we define mutually consistent sets of
natural and derived discrete operations that preserve the invariants of
the De Rham homology groups and obey a discrete Stokes theorem. By
choosing a specific reconstruction operator we obtain well-known mixed FE,
mimetic FD and covolume methods and explain when they are equivalent.
The second half of the talk will discuss several applications of the
mimetic framework. We will start with a new interpretation of a certain
class of compatible least-squares methods, as discrete realizations of a
Hodge-star operator, obtained from weakly enforced material laws. Among
other things, we will show that least-squares, Galerkin and mixed Galerkin
methods, for a class of second order elliptic problems, can be derived
from a common constrained optimization problem. Our second example will
use the mimetic framework to reformulate the discrete Maxwell's equations
into a system that is dominated by discrete Hodge-Laplace operators. As a
result, the reformulated system can be solved by standard “black-box” AMG
solvers for the Poisson equation. Time permitting, we will conclude with
an example that explains how mimetic discretizations can be used to remap
divergence free fields without advection algorithms.
This talk is based on joint work with M. Gunzburger (CSIT, Florida State
University), M. Shashkov and M. Hyman (Theoretical Division, Los Alamos
National Laboratory).

The Application of Grid technology is finally spreading from engineering and natural science related industrial sectors to other industries with a high demand for computing applications.

Multiscale Simulation Of Biochemical Systems
rescheduled from September 5, 2008
In microscopic systems formed by living cells, the small numbers of some reactant molecules can result in dynamical behavior that is discrete and stochastic rather than continuous and deterministic. An analysis tool that respects these dynamical characteristics is the stochastic simulation algorithm (SSA). Despite recent improvements, as a procedure that simulates every reaction event, the SSA is necessarily inefficient for most realistic problems. There are two main reasons for this, both arising from the multiscale nature of the underlying problem: (1) the presence of multiple timescales (both fast and slow reactions); and (2) the need to include in the simulation both chemical species that are present in relatively small quantities and should be modeled by a discrete stochastic process, and species that are present in larger quantities and are more efficiently modeled by a deterministic differential equation. We will describe several recently developed techniques for multiscale simulation of biochemical systems, and outline some of the future challenges.

What Can Be More Important Than "Faster" And "Bigger"?
For decades, the high-end computing community has come to expect continuing gains in the speed of computation and the size of data storage, and these expectations have consistently been fulfilled in remarkable ways. But \"faster\" and \"bigger\" are not the only things that count. We\'ll show how other factors, such as advances in mathematics and theoretical computer science, are just as important, leading to the obvious conclusion that an optimal strategy needs to be \"faster, bigger, and smarter.\"
