Application of the FETI Method to ASCI Problems: Scalability Results on a Thousand-Processors and Discussion of Highly Heterogeneous Problems

PDF Version Also Available for Download.

Description

We report on the application of the one-level FETI method to the solution of a class of structural problems associated with the Department of Energy's Accelerated Strategic Computing Initiative (ASCI). We focus on numerical and parallel scalability issues,and discuss the treatment by FETI of severe structural heterogeneities. We also report on preliminary performance results obtained on the ASCI Option Red supercomputer configured with as many as one thousand processors, for problems with as many as 5 million degrees of freedom.
