%X In this paper the parallel direct method on multiprocessors with local memoryis considered for finite element structure analysis. In §2 parallel computing of anelement stiffness matrix and an assembly of the global stiffness matrix is descrbed.In §3 two direct algorithms are given for banded linear systems with variable bandwidth in which the coefficients are stored by row-wise interleaving storage or column-wise interleaving storage and data exchange bctween processors by pipelinetransmition. In §4 an upper-bound of the number of processors related the halfbandwidth of the matrix and corresponding optimal parallel efficiency are givenFinally, a numerical example on hypercube architecture computer ipsc-2 is provided.
