An implementation is presented for JAC3D on two massively parallel hypercube computers. JAC3D, a three-dimensional finite element code developed at Sandia, uses several hundred hours of CRAY time each year in solving structural analysis problems. Two major areas of investigation are discussed: (1) the development of general methods, data structures, and routines to communicate information between processors, and (2) the implementation and evaluation of four algorithms to map problems onto the node processors of the hypercube in a load-balanced fashion. The performance of JAC3D on a 1024-processor NCUBE 2 and NCUBE/ten hypercubes is compared with that on a CRAY X-MP: the NCUBE 2 version presently takes 20% of the computer time of a CRAY processor.
