Abstract
In this research, we apply modern high performance computing techniques

to solve an engineering problem, structural analysis of grid stiffened

panels. An existing engineering code, SPANDO, is studied and modified

to execute more efficiently on high performance workstations and

parallel computers. Two new SPANDO packages, a modified sequential SPANDO and

parallel SPANDO, are developed. In developing the new sequential SPANDO,

we use two existing high performance numerical packages: LAPACK and

ARPACK to solve our linear algebra problems. Also, a new block-oriented

algorithm for computing the matrix-vector multiplication w=A^{-1}Bx

is developed. The experimental results show that the new sequential

SPANDO can save over 70% of memory size, and is at least 10 times

faster than the original SPANDO. In parallel SPANDO, ScaLAPACK

and BLACS are used. There are many factors that may affect the performance

of parallel SPANDO. The parallel performance and the affects of these

factors are discussed in this thesis.
