Watercooler: 22 February 2005
The Scientific Watercooler meetings, hosted by the Center for Computation and Visualization, are informal gatherings of researchers who need to use high performance computing to enable their research. These meetings are usually scheduled on the last Tuesday of each month at 4:00PM in the CIT Swig Boardroom.
This month’s meeting agenda will include the following topic:
"Detailed Multi-scale Earthquake Modeling Using Rate and State Friction and the Fast Multipole Method on Parallel Computers"
Presented by Terry Tullis, Professor, Geological Sciences
What determines whether a small earthquake grows into a large one, and is it possible to detect in advance some aspect of the behavior of the system that will indicate when this will happen? A NASA-funded CT project has allowed development of a parallel computer code that uses the Fast Multipole method and thus allows at least hundreds of thousands of boundary elements to be employed. The scaling of compute time with number of elements and number of processors show that the code will be useful for studying earthquake interactions and prediction.
Professor Tullis will discuss this project, the modeling methodology, and the role that HPC has played to model earthquake prediction.
