In this work, parallel preconditioning methods based on ??hierarchical interface decomposition (HID)?? and hybrid parallel programming models were applied to finite-element based simulations of linear elasticity problems in media with heterogeneous material properties. Reverse Cuthill-McKee reordering with cyclic multicoloring (CM-RCM) was applied for parallelism through OpenMP. The developed code...
This paper describes the acousto-optic properties of hole-assisted fibers (HAFs) numerically and experimentally. We show that the HAF beat length between the guided and first higher-order modes has small wavelength dependence compared with that of the single mode fiber and so we can achieve broadband acousto-optic coupling. Ultra-broadband acousto-optic coupling is realized by using a HAF with flattened...

Parallel iterative linear solvers for unstructured grids in FEM application, which were developed for the Earth Simulator (ES), have been ported to various types of SMP cluster supercomputers. Performance of flat-MPI and hybrid parallel programming model has been compared using more than 100 SMP nodes of ES, Hitachi SR8000 and IBM SP-3. Effect of coloring and method for storage of coefficient matrices...
