> The PS3 was too exotic of hardware

Wasn't more an issue that games didn't specifically optimize for cell processors? They had to run on dozens of platforms and the Cell processor was the odd one out.

There were at least three largish cluster setups, the biggest being a super computer with almost 2000 PS3s. Of course you are right, that is barely a blip on their sales.

That’s what being exotic hardware means.


It would be the same issue for whatever supercomputer code you want to run. If you don't specifically target for the Cell SPEs, you're left with a single PPE that could barely keep up with the Pentium 4s and Athlon64s at the time.
