2003 Proceedings of the 2003 ACM/IEEE conference on Supercomputing - SC '03  
Accurate micro-finite element analyses of whole bones require the solution of large sets of algebraic equations.  ...  We analyze the performance of our algebraic multigrid (AMG) methods on problems with over 237 million degrees of freedom on IBM SP parallel computers.  ...  We would like to thank Jeff Fier of IBM at LLNL for performance tuning advice and help with performance monitoring tools. This research  ...

Ultrascalable Implicit Finite Element Analyses in Solid Mechanics with over a Half a Billion Degrees of Freedom

M.F. Adams, H.H. Bayraktar, T.M. Keaveny, P. Papadopoulos
Proceedings of the ACM/IEEE SC2004 Conference  
, application of a mathematically optimal linear solution method on a common large scale computing platform-the IBM SP Power3.  ...  This work is significant because in the domain of unstructured implicit finite element analysis in solid mechanics with complex geometry, this is the first demonstration of a highly parallel, and efficient  ...  We would like to thank Jeff Fier for help with performance advise on the IBM SPs. This research was supported in part by the Department of Energy under DOE Contract No.  ...
