| Summary: | In this thesis we present a parallel implementation of an engineering code which
simulates the deformations caused when forces are applied to a piezoelectric-co
ntrolled smart structure. The parallel simulation, whose domain decomposition r
elies on the finite element representation of the structure, is created with an
emphasis on scalability of both memory requirements and run time. We take into
consideration sequential performance enhancements, the structure of a banded sym
metric positive definite linear system, and the overhead required to completely
distribute the problem across the processors. The resulting code is scalable, w
ith the exception of a banded Cholesky factorization, which does not fully utili
ze the parallel environment. === Master of Science |
