Objectives and significance

Develop large scale earthquake simulations on extreme scale supercomputer system

Improve parallel performance of the existing AWP-ODC-GPU code, get comparison results on both China and US Petascale systems

Develop AMR/DM capabilities added to AWP-ODC, capable of resolving the rupture process and wave propagation over orders of magnitude in length and time scales

Objectives and significance

Incorporate inelastic off-fault response into AWP-ODC

Implement fully nonlinear 3D soil response into AWP-ODC

Visual analysis on wave propagation

Need for and Impact of China-US Collaboration

NSF and NSFC give support for this project Improve both earthquake simulation height An example for multidisciplinary, especially

on Geoscience and computer science, as well as algorithm and software areas

Will be a milestone for earthquake simulation

Approach and mechanisms

Work together on both side via exchange scholar

Establish a long relationship on both side working group

Build up a platform for earthquake simulation
