[Trilinos-Users] Epetra support for 64 bit indexing and 3D decomposition with Galeri

[Natarajan CS]

Mike,
      Thanks for the quick response.This is great news!! I do use AztecOO
and ML but I think I can easily change that interface.

I wasn't looking for anything more actually, Galeri fits my purpose to a T.
I was just wondering if this was the only package available to do a
processor decomposition. I understand that LB with Zoltan is probably more
preferable in many applications, however, we have some FD codes that can use
static decompositions without worrying about LB, so was just curious about
the options.
