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

[Jed Brown]

The current implementation uses one-sided because that was a natural. I
need a solid day to implement without one-sided. As stated in the issue I
posted, this is necessary because Open MPI data types are broken.
