Ah, I see. Thank you all for the fast replies. I went with PETSc's
VecReciprocal().

If you are only using PETSc, the efficient way to do this is to get
the raw petsc vector via the wrapper (wrappervec.vec()) and then use
that with VecReciprocal function. If you are using Trilinos, I believe
there is also a reciprocal function that takes an EPetraVector to do
the same.
If need be,

If you
Hi folks
how would I compute the element-wise reciprocal of a ghosted NumericVector in
parallel? While I can just iterate through all entries i and do v.set(i,
1/v(i)) in serial mode, the solution in parallel with ghosts is not at all
obvious to me.
In case you're wondering: I can't fill v wit
