Abstract: In this work, "PHIDAL (Parallel Hierarchical Interface Decomposition Algorithm)"
and a hybrid parallel programming model have been implemented to a finite-element application
for linear-elastic simulations with heterogeneous material property using parallel preconditioned iterative solvers.
Reverse Cuthill-McKee reordering with cyclic multicoloring (CM-RCM) has been applied for parallelism on each SMP node through OpenMP.
Developed code has been tested on IBM p5-575 and TSUBAME Grid Cluster with up to 512 cores.
Preconditioners based on PHIDAL provide much more excellent scalable performance and robustness on both architectures than original block
Jacobi-type localized preconditioners.
