A compute and transfer approach was used for the parallel solution of the 
boundary element method on the IBM SP-1 at the IBM T. J. Watson Research Center.
The figure depicts the solution for the exterior Neumann problem on an 
ellipsoid. The data was distributed over processors in a 2-D block cyclic
manner.  Element integral values  were generated in parallel and communicated
to the appropriate processors using message aggregation.  The highly-tuned
dense matrix LU factorization and solve routines from SCALAPACK were used
to solve for the value of the field at the nodal points on the triangulated
surface.  For a typical problem with 2050 nodal points (matrix size 
2050~x~2050), an overall speedup of 10.49 was obtained on 16 processors
on the IBM SP-1.
