We present distributed algorithms for the finite-element (FE) analysis
of large structures on a loosely coupled multicomputer such as a clus
ter of inexpensive workstations. The focus is on the development of a
coarse-grained preconditioned conjugate gradient (PCG) solver based on
the element-by-element approach to solve the resulting system of line
ar equations. To account for the slow communication speed of the ether
net network connecting workstations, techniques such as redundant comp
utations to eliminate communication, efficient data distribution, and
algorithmic restructuring to reduce communication frequency have been
developed to coarsen task granularity. We present a data distribution
and data movement strategy based on set theory. Due to the general nat
ure of the data distribution scheme, the algorithms are versatile and
can be applied to the analysis of unstructured FE domains consisting o
f a combination of various types of elements.
