When will this project get GPU support? |

It lost GPU support with the end of Separation over a year ago and according to the information in "News" there are currently no plans to release N-Body GPU app.

Did it get discarded? And who broke the profile picture upload mechanism? The above was double spaced between sentences, I apologise for the forum software ruining my post. |

Are there any programming geniuses out there that might be able to help out with bringing GPU support to this project outside of the Miklyway@home team? I wish I could help out, but I have absolutely zero programming skills and/or understanding. To my newbie and knowledgeable understanding, GPU processors can process WAY more information WAY faster than a CPU, right? Either way, I'm happy to help crunch numbers. This project is VERY important so we can accurately pinpoint where Borg space starts and stops. ;-) |

Graphics cards do some things faster, some things a similar speed, some things slower, and some things not at all. Their processors are completely different, they do simpler instructions but thousands at once. So it may not be possible.There was once a plan for nbody on GPU. Did it get discarded?Yes, it was discarded because it was painfully slow and the Milkyway@home team does not have the ressources to work on it. I hope it is, because when they did it for the now finished Milkyway Seperation, a gain of times 80 speed resulted! It was so fast they had to bundle 5 tasks in one to stop the server getting overloaded. I was still getting 300 per card at a time and doing all those (5x300=1500 tasks) on one card in a few hours. There were programmers who optimized seti a while ago, I think they now hang out in Einstein. They may be able to help, can't remember their names though, ask in there.
