Prentice:

For the money you could buy a lot more real computational cycles that last a lot longer than anything proprietary from IBM.  The reason the Origins have been out of production for a long time is the result of research moving to a commodity server platform.  Taken a look at what Cray offers lately?  Looks a lot like commodity.  If you are going to take the time to port code, it seems that a reasonable argument could be made to stay away from Blue Gene and port to Cuda or Phi.

Bret,

You lost me, and I think many other beowulfers on that one. If you look at the top 500, there's plenty of Blue Genes near the top, and Origins have been out of production for a very long time.
