How many problems can these systems really solve? (Score 3, Insightful)

All this effort at creating parallel computing ends up solving very few problems. HPC has been struggling with parallelism for decades, and no easy solutions found yet. Note that these computers are aimed at solving a particular problem (e.g. modeling weather) and not at being a vehicle to quickly solve any problem. When the comparable multi-processing capacity is in your cell phone, what are you going to do with it?
