Posted 2 Sep 2013 by Andrew Dicker Post: I like the lightyear landmark idea, especially how is isn't necessarily in just a boring 2^x or 10^x progression like most project's badges. My astronomy degree slightly dislikes using Universe landmarks for MILKYWAY@home, but that's just a background niggle. |

Posted 24 Jun 2013 by Andrew Dicker Post: Yeah, the first link was "Validation inconclusive" when I posted it, but became valid later. 6dp sounds fine, the difference i noticed was much less significant. I had a large number of tasks validate (~60) before removing my app_info and going back to standard apps. (note the computer may change ID, I seem to have to remove and re-attach the project and merge computers after fiddling with app_info) |

Posted 23 Jun 2013 by Andrew Dicker Post: See http://milkyway.cs.rpi.edu/milkyway/forum_thread.php?id=3276&postid=59036 There's an issue with OpenCL versions on Macs. |

Posted 22 Jun 2013 by Andrew Dicker Post: google shows this for the error: http://software.intel.com/en-us/forums/topic/280040 http://www.khronos.org/registry/cl/sdk/1.2/docs/man/xhtml/constant.html So i guess we need (lines 175-176 of probabilities_kernel.cl): __constant SC* sc __attribute__((max_constant_size(NSTREAM * sizeof(SC)))), __constant real* sg_dx __attribute__((max_constant_size(256 * sizeof(real)))), I'll check this out soonish |

Posted 22 Jun 2013 by Andrew Dicker Post: I'm willing to fiddle around if you need some debugging info or anything. Also, be aware that my machines are using pre-release OS, so it is entirely likely something is broken OS-side. For example, OpenCL 1.2 in the 680MX driver is very new. |

Posted 22 Jun 2013 by Andrew Dicker Post: Cheers, I noticed the new run, don't think i've gotten any GPU WUs yet to check how it runs though. Are the requirements the same as for the other (Win/Linux only) GPU apps? I have two machines, one with a 680MX, 2GB VRAM, and one 330M, 512MB. Should I keep an eye on them both, or only expect WU for the 680MX? I'll report back when I get some on either. EDIT: I tell a lie, checking my task list from overnight results in seeing http://milkyway.cs.rpi.edu/milkyway/result.php?resultid=506354700 among others from the 680MX. A fail. |

Posted 15 Jun 2013 by Andrew Dicker Post: Hi all, What chances are there of getting an OpenCL or CUDA milky way app for Mac? I managed to compile a separation binary http://milkyway.cs.rpi.edu/milkyway/result.php?resultid=500657055 but got computation errors due to the OpenCL kernel not compiling (sorry, logs vanished, i forgot to save them before resetting the project when removing my app_info). Regards, Andrew (also: screensaver apps? i got nbody to compile for mac, but not separation) |
