Just for the record, you tried it on 64bit Linux? mic. |

Type Thank you speedimic for your help i really appreciate it. yes i did it and after some corrections i had to do, i can't find solution on this error: /usr/lib64/gcc/x86_64-suse-linux/4.3/../../../../x86_64-suse-linux/bin/ld: cannot find -lboinc_api collect2: ld returned 1 exit status make: *** [app_x86_64] error 1 whats wrong? what i have to do to build the client for my 64 machine? |

Type Follow the instructions I posted at the top to compile the BOINC API library. If you've done that, make sure the paths at the top of the file point to the correct directory. |

yess my client for Linux64 its ready, i had to add something on my makefile! i've tested the application as speedimic suggested with typing following in my console : ./milkyway_0.7_x86_64-pc-linux-gnu astronomy_parameters-cut-large.txt And i got no errors. After this i replaced the stock application with my optimized but i can't download new wus. Boinc reports : download failed !! what i have to do now? Any suggestions? EDIT : I got my first wus and the client started normally, now im waiting to see if the optimized client runs faster than the stock client! |

The optimized client for Linux64 (sse3) its about 10% faster than the stock app. If anyone has interest for a test use the download Link. http://uploading.com/files/OYAARQ8U/MW-unix64.tar.html |

Kind of a silly question, but since it is Christmas and there is a slow down at uni here. Would be interesting for me to try (especially since I am waiting for several instances of my research work to run on the HPC). How would you go about compiling a 32bit Win (XP) version? I have the 0.7 source (which has make files for linux and osx) and gcc-g++-4.3.2. I assume I would have to get the libraries as well. But with no make file for Win (probably because it doesn't use one) I don't really know the procedure. Looking at the linux make file I see references to the operating environment I would assume they would have to be changed to match the Win 32bit OS? I mainly want to add in sse? support/usage since my systems have it and the current 32bit app doesn't use it. Never surrender and never give up. In the darkest hour there is always hope. |

How would you go about compiling a 32bit Win (XP) version? Yes, you would probably need Microsoft's Visual C++ compiler. However, it's also possible that the Windows application uses a different source. Travis, do you have any input? What compiler, options, and source do you use? |

For all unix/linux Milkyway guys here now you can download my new Unix/Linux 64 client, it runs 50% faster than the stock. http://rapidshare.com/files/176036647/MW-Unixpower.tar The client has been tested to a system with a kernel 2.6.xx and Intel cpu. |

hi speedimic, I didn't made any changes to the application code, if this is the sense of the question ,but im planning to do it the next weeks. You can test my new client for Unix/Linux @ 64 ,it offers 25 % more performance in comparison to my last client. Update: New client for Unix/Linux @ 64 Unix64-Xtrem The new client has been tested successfully to a machine with a modern Intel cpu and Linux @ 64 with 2.6.25.xxxxxx Kernel. Happy crunching and a Happy new Year! |

Hell, that one's fast! Here are the numbers for my Q9550 (fedora 10 x64): stock app: 38min my app: 27min petros app(1): 24min petros app(2): 18-19min How did you get there? For my app I used the latest Intel compiler and this options: -O3 -msse4.1 -xSSE4.1 -fast -fomit-frame-pointer -funroll-loops -unroll-aggressive Happy new year for you, too! mic. |

Petros Great job. My WU times have dropped from 22 mins with your old app to mid 16's for the new one. Keep squeezing. Glenn |

hi, I just moved from Ubuntu 32bit to fedora 64bit yesterday, so I still got to build up my dev-environment... Though I'm sceptic if just the -xS will do the trick, I'll give it a shot. Till then I stick to your build. mic. |

hi guys can you please test this client for SSE4.1 architecture? All of you with the last generation Intel cpus you can use this client! Unix/Linux@64-Xtrem-SSE4.1 client please let me know if the client runs faster! thank you! |
