Report any problems here. These won't validate against the older versions since part of the likelihood calculation changed. |

Is the version 0.2 or 0.02? On the "Applications" page, it's listed as 0.02, and my BOINC manager seems to be having problems downloading the 0.2 version for Windows (32 bit). |

Now at 0.21 because I am good at releases. Also new visible features include an OpenMP version on OS X. There would be a Linux one but I ran into a mysterious issue with my Linux BOINC libraries. MinGW seems to not support OpenMP, so Windows will be later. |

hello, How to receive, because right now I only have 0.07? Perhaps with a link to the file this under 0.21 and a change in the app_info would suffice? thank you Team Alliance francophone, boinc: 7.0.18 GA-P55-UD5, i7 860, Win 7 64 bits, 8g DDR3, GTX 470 |

Probably won't make any difference, but are you using the TDM-GCC builds? (for MinGW) |

Perusing the logs on one of my (old laptop) crunchers I encountered the message: 11/4/2010 12:47:22 PM Message from server: MilkyWay@Home N-Body Simulation needs 476.84 MB RAM but only 444.98 MB is available for use. So, it seems the N-body program is getting to be like Cosmology@Home in terms of being a memory hog. In some ways, I think the processing is similar. C@H maps how density fluctuations evolve in a potential field (that responds to the density fluctuations), M@H is mapping how stars evolve/move in a potential field that reacts to the star positions.

Perusing the logs on one of my (old laptop) crunchers I encountered the message:The N-body doesn't need that much memory. 15MB at most would be a high estimate for the 32k body workunits, which are the current largest. |

If it hasn't already been reported, there is a typo in that quoted app_info.xml. The word "intel" is not needed to agree with the name of the file to download. For Windows 7 x64: milkyway_nbody_0.21_windows_x86_64__sse2.exe And replace the part for nbody in your app_info.xml with: <app> <name>milkyway_nbody</name> <user_friendly_name>MilkyWay@Home nbody Simulation</user_friendly_name> </app> <file_info> <name>milkyway_nbody_0.21_windows_intelx86_64__sse2.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway_nbody</app_name> <version_num>21</version_num> <file_ref> <file_name>milkyway_nbody_0.21_windows_intelx86_64__sse2.exe</file_name> <main_program/> </file_ref> </app_version> Don't drink water, that's the stuff that rusts pipes |

You are right; I did a copy/paste from my file (for Win32) and made that mistake when modifying for Win64. Sorry for that. So, here again for both windows versions with correct exe names: For Win64 it's milkyway_nbody_0.21_windows_x86_64__sse2 <app> <name>milkyway_nbody</name> <user_friendly_name>MilkyWay@Home nbody Simulation</user_friendly_name> </app> <file_info> <name>milkyway_nbody_0.21_windows_x86_64__sse2.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway_nbody</app_name> <version_num>21</version_num> <file_ref> <file_name>milkyway_nbody_0.21_windows_x86_64__sse2.exe</file_name> <main_program/> </file_ref> </app_version> and for Win32 it's milkyway_nbody_0.21_windows_intelx86__sse2 <app> <name>milkyway_nbody</name> <user_friendly_name>MilkyWay@Home nbody Simulation</user_friendly_name> </app> <file_info> <name>milkyway_nbody_0.21_windows_intelx86__sse2.exe</name> <executable/> </file_info> <app_version> <app_name>milkyway_nbody</app_name> <version_num>21</version_num> <file_ref> <file_name>milkyway_nbody_0.21_windows_intelx86__sse2.exe</file_name> <main_program/> </file_ref> </app_version> |

It happened again, so I think there's an error in the build configuration for the N-body application that it tells BOINC client that it needs that much RAM.
