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 with the desired reciprocal values in 
the first place, because the entries to be inverted are sums of element 
contributions.

Cheers,

Roman
