 > I would disagree with that. Running on a workstation is probably one of
 the the first things new users do, and this has to work out of the box at
 reasonable speed. For production, of course, that is not that common.

 Activating SystemTopology would only be harmful if the user is running
 multiple independent Cactus simulations on the same workstation. In that
 case, SystemTopology would place all Cactus instances on the same core and
 degrade performances significantly.
