[Trilinos-Users] Zoltan question

[Erik Boman]

John,

Zoltan assumes "everyone" has MPI on parallel machines so there is no 
abstraction layer above that. However, Zoltan only uses a small subset 
of MPI so you could implement that subset in your own messaging library 
and link with that as a "fake" MPI library. We use that approach for 
serial builds, so it should work.
