PETSc could also just provide a VecReduce and VecReduceStride operation, which might simplify the programming effort a bit.</blockquote></div><br></div><div>That would be neat, especially if it used MPI_Op for the reduction. You would need MPI-2.2 to have MPI_Reduce_local() for user-defined operations, but it would be more flexible and less code than the current approach.</div>
