We put out a query within IBM back in November 2006 to find out what can be done with the PS3. We are well aware of the publicity value of a distributed computer program on a console, but we need an outside project that meets our requirements. OK, thanks for the clarification. Good to know that this IS being thought of, we'll just see if anything comes out from this. Keep my PS3 folding for now, all my PCs are on WCG now for the Christmas Race, after that we'll see. |

I'm sorry I guess I'm a little slow. What would those be? If I install Yellow Dog or some other linux on the system why can't I use Boinc for Linux? on PS3grid there is BOINC for PS3... |

And SETI and yoyo has applications which use the SPEs, too. SIMAP has a PPE only application for the PS3. [Edit 1 times, last edit by Dotsch at Dec 22, 2007 10:50:02 PM] |

Here's a funny quote from the main project using the PS3 and the acknowledgement:
----------------------------------------The GPU client is still the fastest, but it is the least flexible and can only run a very, very limited set of WU's.

Here's a funny quote from the main project using the PS3 and the acknowledgement: The GPU client is still the fastest, but it is the least flexible and can only run a very, very limited set of WU's. Yes the GPUs are fairly limited currently; PS3 is more flexible though: The PS3 right now runs what are called implicit solvation calculations, including some simple ones (sigmodal dependent dielectric) and some more sophisticated ones (AGBNP, a type of Generalized Born method from Prof. Ron Levy's group at Rutgers). In this respect, the PS3 client is much like our GPU client. However, the PS3 client is more flexible, in that it can also run explicit solvent calculations as well, although not at the same speed increase relative to PC's. We are working to increase the speed of explicit solvent on the PS3 and would then run these calculations on the PS3 as well. In a nutshell, the PS3 takes the middle ground between GPU's (extreme speed, but at limited types of WU's) and CPU's (less speed, but more flexibility in types of WU's). |

That is flops can be calculated in lots of different ways - and they just picked the method that yielded the biggest numbers (probably due to pressure from Sony). The result is that the numbers from the Folding@Home project can't be compared meaningfully to anything else - they exist in their own bubble of meaninglessness. Consoles do have potential, of course. But the console manufacturers have been spinning lies about performance for so long it seems to be a habit. Seriously, though - if the chip in a PS3 were really as good as they claim, they would be in every desktop by now. The reality is that cell CPUs are very specialised, and only good at certain operations. They are useless for general purpose computing. The next generation of general purpose cell processors - now that will be fun. Are the GPU flop #s from F@H "misleading" also? http://science.officeisp.net/ManycoreComputin...ions/Dinesh%20Manocha.ppt http://www.cs.utk.edu/~tomov/GPU_CDIC.ppt |

GPUs are even more specialised, and it is even more misleading to compare them directly to CPU architectures.

The one thing to consider when evaluating GPU's for grid computing is it adds a dimension of complexity in programming and support. This coupled with the problem of the primary cost of personnel, would drive the bottom line here so high that they would have to drop projects to accommodate this new concept. So the reason why you see it elsewhere is they run just one project.
----------------------------------------The gain touted by use of GPU's is also misleading. As the instruction sets and the hardware itself is optimized for graphics. This makes the concept of using this really a work-around.     |
