This proposal will demonstrate a software infrastructure specialized to study of cerbrovasculature. The problem is of great societal importance and is typical of a number of multiscale multiphysics problems encountered in multiple branches of science. The investigators will focus in this project on:? Scalable Continuum Models using their highly accurate hp adaptive spectral element code NEKTAR, ? Stochastic Continuum/Atomistic Modeling (LAMMPS-DPD); ? Multi-Level Parallelism, and, finally an effort to make computing across multiple grids by doing a pilot of TeraGrid-DEISA Grid Computing.

该提案将展示专门用于研究脑血管系统的软件基础设施。该问题具有重大社会重要性，是多个科学分支中遇到的许多多尺度多物理问题的典型。研究人员将在该项目中重点关注：？可扩展的连续体模型使用其高精度 hp 自适应光谱元素代码 NEKTAR，？随机连续体/原子建模 (LAMMPS-DPD)； ？多级并行，最后通过 TeraGrid-DEISA 网格计算试点来实现跨多个网格的计算。
