http://aerospaceresearch.net/constellation/ Constellation is presently by invitation only, it does not yet have a public project. Orbit has had no tasks for some time - it is very intermittant. Einstein is an Astrophysics project, not an Astronomy project. None of the multiple application projects run Astronomy apps. |

No, I mean the gravitational potential.the real point is to find a model for the Milkyway's potential |

Is this new update to separation 0.50 going to break all of us with the optimized applications? I'm running Fedora Linux x86_64. Lately, tasks continue to run and finish, but there are a a lot of "validation inconclusive" results. My current applications are: milkyway_0.18_sse4.2_x86_64-pc-linux-gnu milkyway_nbody_0.07_x86_64-pc-linux-gnu |

Hi, a lot of MilkyWay@Home v0.50 (cuda_opencl) de_separation ending with computing errors! I have updated the NVIDIA Geforce GTX 285 from 260.99 to 266.58, running two cards on INTEL i7-965 3.2GHz quad, 8 processors, MS Vista 64 bit, SP2. The computing errors are still there. Kind regards, Ronald |

Hi, tasks MilkyWay@Home v0.50 (cuda_opencl) de_separation with ....fix_1 ending on my NVIDIA Geforce GTX 285 cards with comuting error, ....fix_2 is always running fine on these cards. I saw, that ... fix_1 is running fine on ATI-Graphic cards. my former message: a lot of MilkyWay@Home v0.50 (cuda_opencl) de_separation ending with computing errors!

Hi, if you need some more infos about our Constellation platform, just ask me. But perhaps not in this thread, because I think it's offtipoic then. And yes, we're not public yet, but we work on it. Andreas |

Hi,I think I know what the problem is. My formula fell apart for those size workunits with those GPUs. |

I am having errors as described here on a previously stable dual 260 gtx http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=2176#45717 |

Hi tasks of MilkyWay@Home v0.50 (cuda_opencl) de_separation_23_3s_fix_1_..... ending all with computing errors! I have updated the NVIDIA Geforce GTX 285 from 260.99 to 266.58, running two cards on INTEL i7-965 3.2GHz quad, 8 processors, MS Vista 64 bit, SP2. The computing errors are currently only with the above tasks occuring. Kind regards, Ronald |

HiI'm aware. I'll fix it as soon as I can. My main development machines are all sort of ripped apart right now. |

My current applications are: OK, I updated to: milkyway_0.50_x86_64-pc-linux-gnu__sse2 milkyway_nbody_0.21_i686-pc-linux-gnu__sse2 For some reason, if I let BOINC go back to stock, it doesn't use the sse2 app for NBody. So, I'm forcing the i686 SSE2 app with my app_info.xml file. As long as someone posts a thread such as "Updated MW to version 0.50" in the News forum, my RSS reader will alert me so I can update my applications. |

I wasn't sure because it's not listed as such on the applications page. http://milkyway.cs.rpi.edu/milkyway/apps.php If everything requires SSE2, then simplier to just leave off the "(see2)". In 2011, I'd bet 99.9% of the CPUs attached to this project support SSE2. |

Thanks a lot for your explanation... It gave me a clearer picture... and hope our efforts are well put then! Good luck to us all. |

Any plans to suport GPU work on OSX? I have a GPU I would love to put to work on this project. |
