[petsc-users] Are there any functions (objects ) for scattering and gathering 64-bit integers just like VecScatter for PetscScalar?

[Jed Brown]

I am using PetscSF for this. You would need petsc-dev and the current
implementation requires an MPI with non-broken data types.

Here are some (dated) notes about the communication model.
