[Trilinos-Users] 2D partitioning on sparse matrix vector multiplication

[Da Zheng]

Hello,

Sparse matrix vector multiplication in Tpetra or Epetra by default
uses 1D partitioning on the sparse matrix for parallelization. What is
the right way to do 2D partitioning on the sparse matrix? I guess we
need to use Zoltan to do things like that. Hopefully, it's not very
complex. Is there any example code for this?

Thanks,
Da
