To appear in the SIAM Journal on Scientific Computing special issue on the Fifth Copper Mountain Conference on Iterative Methods . Standard finite differences are used to discretize the equations, yielding 5-pt. This solver can serve as a key component for achieving scalability in radiation diffusion simulations.
Parallelism is achieved by data decomposition.
C. Parallelization SMG98 is a highly synchronous code. This code is memory-access bound. Iteration counts will also increase slightly for small to modest sized problems, then level off at a roughly constant number for larger problem sizes. These results were obtained on ASCI Red. ID All of the arguments are optional.
