[Trilinos-Users] [EXTERNAL] pytrilinos submodules import error

[Bill Spotz]

Romain,

During configuration, PyTrilinos now looks for mpi4py, and if it finds it, enables some interoperability with it.  The main advantage is it allows you to define sub-communicators if you want them.

I have run into a problem on the Mac where mpi4py tries to load its MPI.so but instead gets Boost's mpi.so.  Could this be happening to you?

I should probably add a way to explicitly turn mpi4py support off.
