Abstract:
|
PARPACK is an open -source Arnoldi /Lanczos eigensolver package which is compatible with a number of distributed parallel computing schemes . This thesis concentrates on a set of driver routines for PARPACK that were developed for use in the Automated Multilevel Substructuring (AMLS ) vibration analysis software package developed at The University of Texas at Austin . AMLS requires many truncated eigensolutions to
symmetric generalized algebraic eigenvalue problems . There is a need in AMLS to solve these problems in several different computing regimes , from serial execution on a single processor , to parallel execution on multiple nodes of a distributed computing cluster . This work is designed
to enable evaluation , selection , and development of PARPACK capabilities for the variety of eigensolutions required by AMLS . |
