This should come as a relief to many researchers who previously had been using PS3′s to run linux clusters in super-computing applications. As this article about the U.S. Airforce’s PS3 cluster noted, they had to wind down the project because Sony removed the “otherOS” feature which made this project possible.

Now, with the PS3 hacked wide open it would be possible to use newer PS3s again. Of course this isn’t likely since it violates U.S. law (DMCA)…

Other than the publicity it’s getting, there isn’t much thats new here. The PS3 has a been able to run “guest” operating systems such as Linux since it was released. Sony has even had some of its own employees working on improving it. And using Linux as an inexpensive clustering environment is certainly not new but it is still really cool to see something like this put together.
