As soon the Nvidia is ready I'm up for testing it on my 9600M GT. If the project does not drop the double precision requirements, it will also require very recent nvidia cards (CUDA compute capabilities 1.3 required, your 9600GT supports 1.1). That means only the GTX 200 line will work. That is the same the reason the ATI GPU app is only available for HD3800 and HD4800 cards. |

And I don't think that the SETI CUDA is available for Macs yet either. I think they are still waiting for Snow Leopard and open CL to work on porting. Don't forget that there is no official AP app either. |

And I don't think that the SETI CUDA is available for Macs yet either. I'm pretty sure I'll be getting one of the new macbook pro's (my current one is in need of an upgrade), so you can bet there'll be a Mac OpenCL (or CUDA if snow leopard isn't out yet) version shortly after I get that :) |

And I don't think that the SETI CUDA is available for Macs yet either. No, there aren't any CUDA libraries from Nvidia for Mac yet, that's what he meant. Apparently they're being worked on. As I got my new MacBook with GeForce 9400M graphics, I look forward to those. |

And I don't think that the SETI CUDA is available for Macs yet either. There are CUDA libraries for OS X. The OpenCL libraries are the ones being worked on for snow leopard. At any rate my laptop is too old to have a graphics card that supports CUDA, so I can't do too much work on one yet. |

The CUDA capability is built in in the 6.6 clients for the Mac, but they won't be enabled until nVidia releases the 64bit drivers that enables CUDA on the Mac. Of course, even then it doesn't help much as none of the projects have an application at the ready. Jord. The BOINC FAQ Service. |

In theory all that would be required is that they compile their application with the Mac as the target using the Nvidia API ... of course we all know that it is not likely to be that easy ... and it also means that the project has to get a Mac to do so ... Sadly, the community is still small enough that we can be ignored, though I think that there are more Mac users than Linux ... We also have ATI cards for the Mac so it will be interesting to see which comes first ... if any ... |

And as for ATI cards in Mac, I don't think any of them are double-precision capable like what MW needs, plus Apple seems to be moving towards the Nvidia cards nowadays. We'll have to see where this goes in the future. |

1) Any news on the Nvidia app? 2) Will it work on the 9x series? Yeah the only current GPU app for milkyway is Cluster Physik's which uses ATI cards. We're working on one for Nvidia. A BLAST FROM YOUR PAST |

I'm getting a 3870 to help crunch on a Vista 64 machine. Do I have to use optimized apps in order to use the gpu, or is it done automatically? Also, if I need to use optimized apps, how do I go about it? Depending on how many WU a 3870 can crunch at a time, I may get another 3870 to crunch on another machine. |

Remember, only the 8.12 or 9.1 drivers work - don't use the later 9.2 (9.1 drivers never worked for me) |

Thanks Ice, I think I got it. I wish I could put a 4870, but it's a Dell, and it's cramped in there. 3870 is the best that fits in the machine and in my budget. |

Ice, I've got the 3870 installed, Catalyst 9.1 drivers, no other application running, only Boinc with the optimized apps for ATI GPU (0.19d Win64), but it's crashing the graphics driver very often (the Catalyst Control Center is not running in the background). I can't leave my computer crunching away without checking up on it from time to time. Is it the nature of the beast as it's not a final version? When it does work it's very fast, making my Dell AMD dual core nearly beat my Mac Pro with 8 cores! |

I've never managed to get the 9.1 drivers to work, and the 8.12 drivers are working well with my HD4870. I tried the 9.2 drivers with my HD4870 as well as the 9.1, which worked for a while and then not in both cases, so I reverted to the 8.12 drivers and everything is well again and runs fine. I'm using optimized app version 0.19d. |
