Hi,

I am using DMDAVecGetArrayF90 with a pointer in petsc 3.4.3. Is there anyway of 
finding out what the start and finish indices of the pointer coming back from 
this routine are per processor?

I have declared:


DM                              ::   da
Vec                             ::  X
PetscScalar,pointer      :: xv(:,:)=>null()


DMDAVecGetArrayF90(da,X,xv,ierr)


Do j = 1, m
  Do i = 1, n
    xv(i-1.j-1) = rhs2d(i,j)
  enddo
enddo


DMDAVecRestoreArrayF90(da,X,xv,ierr)

When we have xv(0:n-1,0:m-1) from DMDAVecGetArrayF90 it works fine but other 
processors may give back eg; xv(0:n-1,1:m-1) or something else and it will fail 
as the second index
now goes below 0 to 1. Any ideas of what I can do next?


Thanks,

Carol
