It's not entirely embarrassingly parallel because photons from nearby light sources interact, so you need to do a parameter exchange. That said, it is true that it doesn't need the low latency fabric that supercomputers traditionally used (though these days the architecture isn't all that different from what you'd have in a traditional data center). We were actually approached by Microsoft to duplicate the demo on Azure, but they ended up being unable to find enough spare capacity for us to run it at full scale, so we showed off a small scale demo. In this particular case, the supercomputing center was quite interested in our application because they wanted to test their setup with more "data analysis heavy" workloads, since they had invested a lot in SSD caches for this kind of work, but most of their workloads didn't require it.
