I might be completely off my rocker here, but I would believe mpipov to be
The version of mpipov I saw renders a block of lines on each process, and
there is no mpi communication between setup and final data except
housekeeping, so the network will probably be bored most of the time.
Each process renders one pixel after another, so unless you have a really
advanced scene/texture stack, I would guess you don't have to worry much
about cpu cache.
Also, unless your scene is very complex, and the segment rendered by each
node is very large I would think that memory should not be a problem either.
That leaves CPU speed (and, to a lesser degree, memory speed) as the
