Over the past decade, improvements in the numerical and computational algorithms, combined with the increase in computing power, have stimulated scientists to build more complex mathematical models in various domain application areas, which rely on lesser number of simplifying assumptions. In these models, the multiscale nature of physical systems is apparent, e.g., in materials science, biological systems, chemistry, complex flows, etc. These models are thus highly complex and our success in using these models to solve problems hinges upon a deeper understanding of their mathematical structure. The DOE is in the process of developing a roadmap for future investments by the DOE in multiscale mathematics and is seeking input from the engineering, mathematics, and scientific communities through a series of workshops. The current workshop is the third of a series of DOE Workshop on Multiscale Mathematics which are held to draw community input needed to develop the Multiscale Mathematics roadmap; see the websites: http://www.math.colostate.edu/~estep/doe_multiscale/DOE_Multiscale_2.html http://www-fp.mcs.anl.gov/multiscale-workshop/ for information regarding the previous two workshops. This community effort is inspired by the FY 2005 budget, which includes $8,500,000 for the new "Atomic to Macroscopic Mathematics" (AMM) research effort. This funding is intended to provide the Applied Mathematics research that is needed to break through the current barriers in our understanding of complex physical processes that occur on a wide range of interacting length- and time-scales and the mathematical structure of their models. ------ Subject: Postdoctoral Position at University College London From: Peter Coveney Date: Thu, 9 Sep 2004 11:56:44 -0400 (EDT) BBBSRC & EPSRC FUNDED POST-DOCTORAL RESEARCH FELLOWSHIPS CENTRE FOR COMPUTATIONAL SCIENCE University College London High performance computing, visualisation and steering on grids Applications are invited for several openings, suitable for theoretical and computational scientists, to work on a number of projects including: (i) Mesoscale and multiscale modelling and simulation of condensed matter systems (including biological systems); (ii) Development of robust environments for the deployment of the associated scientific codes on computational grids, including both workstation and high performance computing class applications.
