I would say that's always true :-) If you can change the way you do things, then adapting to the most appropriate hardware/software combination makes sense to get the maximum of performance. Wait, this has already happened... and then there was chaos... and then came MPI ;-) > How about problems where you send out identical datasets to (say) a > farm of GPUs. You still need to send point-to-point data forth (what to do with the bulk data) and back (the results). Then you have the big problem of synchronizing the 2 channels: the broadcast one and the point-to-point one. This can come from either GPUs taking different time to finish or from point-to-point communication delays/congestion. And then the efficiency brought by broadcast might just go away...
