My Playstation 3 came with application for crunching folding at home on it. Is there any plans on being able to run Rosetta on the Playstation 3? I would really rather be doing that with it since it sits idle more then my puter does.

No specific plans have been announced.

Rosetta Moderator: Mod.Sense

Sign up for Folding@Home. I just did, for my two ps/3's.

If you feel up to it, you can install a (Yellow Dog) Linux os on the ps/3, and then install Boinc.

Boinc projects that maximize use of the ps/3's six spe's: PS3Grid, Yoyo@Home's OGR-25 project, and possibly Seti.

Boinc project that will use the ps/3's one ppe: Simap.

The Rosetta Project is refusing to comment to its donors on the potential use of gpu's and gaming consoles for processing their work units.

Not exactly "refusing", but they haven't updated us in a while.

There were mentions of talks with Microsoft and also early stage projects to do SSE optimizations. I can't remember anything official about the PS3.

"This is democratic computing, so it's based on the goodwill of a bunch of people from all walks of life, all backgrounds," Wandelt said. "If as a researcher you cannot communicate..., this sort of thing probably isn't for you."

Hey, I agree that more communication is better. But it's not because they haven't updated us in a while that they are sitting idle.

I know they're working on the interactive game, which would be pretty cutting edge in the field.

Dr. Baker mentioned that a new version of the Rosetta software with cleaner code and a smaller memory footprint is coming (IIRC).

And each point upgrade seems to be able to do more science, which is great.

For all we know, they might also be working on paper for scientific journals or preparing CASPM or something, which could explain the radio silence.

So as I said, I agree they should try to do a better job of keeping us updated, but I also think Rosetta is a great project with lots of exciting things happening. Science just moves a bit slower than we sometimes wish, and scientific priorities aren't always what we crunchers wish they were...

Lets see if you receive the same type of comment that I did: that the "costs" of anything more than keeping the current code up and running are too great for the Project to "afford".

Rosie can "afford" to develop a game, yet she can't "afford" to just investigate whether the ps/3 could possibly bring them 1 pflop of crunching power, as it did F@H.

I know they're working on the interactive game, which would be pretty cutting edge in the field.

PS 3 <3 nice of machine game

Seems like one of my posts here was censored.

Whatever, just google "david baker" and you can find contact information to ask your question. If he didn't want to be contacted about his project, he wouldn't have put his contact information there so I assume it's okay (a email or fax might be better than a phone call, though).

Boy, those mod's sure are touchy, lol !!!

He/She probably didn't know if it was okay for me to put Dr. Baker's contact info here, probably didn't know if this was public info or not, so I guess this was the precautionary principle.

I guess... if it was his home contact info, I guess I could understand, but he's a college professor, kinda silly to redact his work contact info.

Maybe we shouldn't allow in print that the President of the United States is at 1600 Pennsylvania Ave., in Wash DC, lol !!!

As you said, whatever...

Probably old (2.5 months) news to most, but worth repeating to those who missed it the first time around:


Gamers Help Supercomputing Project Break World Record

"To have Folding@home recognized by Guinness World Records as the most powerful distributed computing network ever is a reflection of the extraordinary worldwide participation by gamers and consumers around the world and for that we are very grateful," Vijay Pande, associate chemistry professor at Stanford University and Folding@home project lead, said in a prepared statement. "Without them we would not be able to make the advancements we have made in our studies of several different diseases. But it is clear that none of this would be even remotely possible without the power of PS3, it has increased our research capabilities by leaps and bounds."

"This record is clear evidence of the power of PS3 and the contributions that it is making to the Folding@home network, and more importantly, scientific research, " Masayuki Chatani, executive VP and CTO of the Technology Platform, Sony Computer Entertainment, said in a prepared statement.

In March, PS3 joined. In six months, the program attracted more than 670,000 unique PS3 machines.

I wonder if the Project is aware of this, or if they've been too busy counting the research dollar$ from Mr. Gate$' foundation, and the Project doesn't want to speak with Sony's Masayuki Chatani, because they would hate to embarra$$ Mr. Gate$' company'$ gaming con$ole...

DOH! How silly.

Angus, I'm really surprised at you, lol !!!

That link contains * gasp * a photograph of the Doc !!!

It's only a matter of time before the mods censor that information!

DOH! How silly.

Please guys, don't assume bad faith, either of the project or of the mods here. It's pointless and nothing good will come out of it.

I certainly hope its not pointless. Perhaps certain people will reflect, and see the folly of their ways...

And the whole thing is accessible from the University of Washington link at the top of every page here. Just follow your nose to the Biochemistry department.

PlayStation3 Gravity Grid

The Sony PlayStation 3 has a number of unique features that make it particularly suited for scientific computation. To start with, the PS3 is an open platform, which essentially means that one can run a different system software on it, for example, PowerPC Linux. Next, it has a revolutionary processor called the Cell processor which was developed by Sony, IBM and Toshiba. This processor has a main CPU, called the PPU and several (six for the PS3) special compute engines, called SPUs available for raw computation. Moreover, each SPU performs vector operations, which implies that it can compute on multiple data, in a single step. Finally, its incredibly low cost makes it very attractive as a scientific computing node, that is part of a cluster. In fact, its highly plausible that the raw computing power per dollar that the PS3 offers, is significantly higher than anything else on the market today!

Thanks to a very generous donation by Sony, we have an eight PS3 cluster in our department, which we call PS3 Gravity Grid. Check out some pictures of the cluster here: 1) the PS3's arrive; 2) the rack arrives; 3) front view of the cluster; 4) side view of the cluster.

We are using "stock" PS3s for this cluster, with no hardware modifications. They are networked together using an inexpensive netgear gigabit switch. For Linux installation, there are several guides available on the internet. For YDL Linux, consider using the guide by Terrasoft Solutions. For Fedora Core 5/6, I found this guide particularly useful. For deploying a parallel job on this cluster, we use a code that implements a standard domain decomposition approach, based on message-passing (MPI). There are more details available on our code below. For compiling, we use GCC and also IBM's XL compilers for the Cell, that are available as part of IBM's Cell SDK. These are available from IBM's alphaworks site. The MPI distribution that we are using is the recently released, OpenMPI distribution for PowerPC Linux.

Overall, a single PS3 performs better than the highest-end desktops available and compares to as many as 25 nodes of an IBM Blue Gene supercomputer. And there is still tremendous scope left for extracting more performance through further optimization. More on that soon.

Furthermore, we distribute the entire computational domain across the eight PS3s using MPI (message passing) parallelization. This enables the entire cluster to run together, harmoniously, working on the computation in an efficient way. Each PS3 works on its part of the domain and communicates the appropriate data to the others, as needed.

I'm afraid the NIH factor will override everything else.

If another University did it, we can't do it because , well, it's Not Invented Here.
