Foil 19 Parallelization of ADI

From Spatial Differencing and ADI Solution of the NAS Benchmarks CPSP713 Case studies in Computational Science -- Spring Semester 1996. by Geoffrey C. Fox
Each tridiagonal solve is not usefully parallelized
However this is not important as one has N 2NAS Independent tridiagonal solves for each of three sweeps
For instance for equation
with components labelled by (i,j,k) for three x h and z directions, the equations for each distinct value of (j,k) are independent.
