A lot of OR stuff can be parallelized, but it isn't a panacea. Those techniques don't necessarily get you the best answer sometimes. My company does some massive optimization problems and although we have lots of cores for all the simulations, any one is pretty much single core + a lot of RAM. It doesn't work well on GPU like some heuristic optimization problems can. Edit: Someone smarter than me says it better below :)
