I have read several threads on this, so I know it has been talked about over and over. This is why I am not posting in the Crunching section.

I purchased my wife a PS3 for Mothers Day. While I was setting up folding@home on it, I sure was wishing it was a rosetta app instead.

In the Folding app, they have lights on a globe that shows where PS3s are in the world and how many are online. I highly doubt it is very accurate, but I still enjoyed seeing all the gamers that are running a useful app while they were not playing. Again, just wish Rosetta was a choice.

Drizzt.

Agreed.

At least there has been very recent communication from the Project that they will again be in contact with MS re a possible xBox application.

Not certain why the xBox appears to be preferred over the PS3, but if they eventually do develop an xBox app, there is hope for (imho, the superior) PS3.

I am cautiously optimistic that this is not just talk, but real action on the part of the Project.

In the interim, both of my PS3's are crunching for F@H, and when I get around to installing linux, I'll likely do some crunching for PS3Grid and yoyo@Home's OGR wrapper.

Well,have you ever notice one logo at the bottom of front page?It is logo of Microsoft research...

There seem to be quite a few difficulties in programming for the PS3:
1. only 256MB system RAM available vs xbox's 512MB
2. only one CPU - the majority of the FPU power is in the six SPEs, which have very little cache each (one of the seven is reserved for the OS i believe?).
3. it's not x86

I'm no expert but I would guess that the combination of 1 & 2 means that the SPEs would have to work in parallel on one target (there's no way six rosetta threads could run in 256MB!), although the recent supercomputer work and minirosetta might make this possible???

The xbox has three cores to the PS3's (very similar) one, but I believe they wouldn't be particularly good at Rosetta (as they're PPC based - unless altivec could be used?). The xbox's xenos GPU would therefore probably be a good target, but then if you can program for that you can probably program for CUDA etc...
