I have heard about the success with which the folding@home program was met on the Playstation 3. It therefore seems that including LHC@home on the Playstation system would be of great benefit to the program. Just an idea/suggestion from an interested LHC fan and Playstation 3 user. |

I don\'t have a Playstation 3 but it seems to me that Sony has put Folding@home in its OS. Can you confirm this? Also visit www.ps3grid.net. Tullio |

PS3 porting is quite not easy... It was discussed some time ago in this thread |

PS3 porting is quite not easy... Also discussed in Nov 2004. http://lhcathome.cern.ch/lhcathome/forum_thread.php?id=1057#5362 The 16 trillion floating point operations per second is still impressive even with today\'s multi core pc\'s. I never did get around to getting one and putting linux on it. I'm not the LHC Alex. Just a number cruncher like everyone else here. |

PS3GRID is a BOINC project that utilises a development version of BOINC (which can be found on the PS3GRID website). The beauty of this project aswell is that if you have one of the newer nvidia based graphics cards you can run utilise it to run PS3GRID on it as well (nicknamed GPUGRID). I have a 9600GT based card in my Q9450 based machine and get close to 3000 cs a day from my GPU on PS3GRID and about 2000cs a day from my Q9450 on Malaria COntrol.net Now if I was running an optimised SETI app that machine alone would be getting close to 9000cs a day! Now if I put a second graphics card in it I can add another 3000cs to it! Holy smokes! Live long and BOINC! |

I think that will not be done, because there is much less work than could be calcullated. If there were more work, I think it would make sense. |

Another problem with the graphics cards/ps3 approach is that the cards are extremely fast single precision machines. Sixtrack however requires double precision. So the speed up is not as big. Another problem is with rounding errors. Sixtrack is very succeptible to incorrect rounding of floating point numbers. It took ages to work out the differences in the intel and amd architectures. It would be a lot of work to be certain that the GPU chips calculate correctly. Thirdly SixTrack as far as i remember relies on a lot of complex floating point math (sin/cos/exp/log) another area where the speed up of the graphics cards are not as impressive as when you can do simple vector operations.

U can use a Linux Live CD Boot into windows and then use the the program and YES u can boot into windows on a ps3! |
