New app version is ready! It is available at the same place as usual: https://bitbucket.org/sirzooro/pc-boinc/downloads/. In order to install it, do following steps: Error is "Permission denied". You need to execute following commands from root account in project dir to set appropriate permissions. If you cannot switch to root account using "su -", add "sudo " before each command. chmod 755 pc
chown boinc.boinc pc
After you do this, app should start working. You do not need to restart BOINC again. ____________ | |

OK, I did that, but now get the message: Message from server: Your app_info.xml file doesn't have a usable version of gene@home PC-IM. EDIT: Also, it won't download more work, since it says the computer has reached the daily quota of 1 task. | |

OK, I did that, but now get the message: I suspect that problem is caused by WUs which you downloaded using official app, which are still considered as in progress. Please try to delete app_info.xml, restart BOINC, wait until BOINC will re-download all these WUs, then abort them all and install optimized app again. Before aborting tasks please also suspend project or set it to "no new tasks" to avoid downloading new WUs in place of aborted ones. BTW, i7-4770 also supports AVX and FMA, you can try these app versions too. ____________ | |

Win10 X64 Thanks for these numbers. I did my tests on Windows using AVX version and it was faster for me. I suspect that new SSE version is slower. but I have to perform additional tests to confirm this. I will let you know when I will have some results. ____________ | |

Win10 X64 I did extra benchmarks using 10 blocks from some VV WU instead of 1 like before. On my Windows machine new SSE app has results similar to AVX app. I also tried to benchmark 32-bit SSE app version and that one was slower than official SSE app. Maybe you downloaded 32-bit app instead of 64-bit one? ____________ | |

This is a test run on my FX8320 with a real vv workunit kept from the project, the same for every app. Best time of 3 runs.

Could someone recommend which version I should be using with Intel L7555 cpus? (4 of them) Looks like thats the best app version for you. http://www.cpu-world.com/CPUs/Xeon/Intel-Xeon%20MP%20L7555%20-%20AT80604004875AA.html | |

Hi daniel, i have a question for you | |

Hi daniel, i have a question for you Your CPU also supports FMA instructions, so you can also try FMA app version: http://www.cpu-world.com/CPUs/Core_i5/Intel-Core%20i5-6400.html. In general FMA app version should be faster than AVX, which is faster than SSE one. However on some CPUs FMA versions for some reason is a bit slower than AVX one, so please try both. It is possible to install few versions, but you would have to rename pc.exe files and modify app_info.xml to specify all app versions with proper plan classes. Files prepared by me are configured to run single app version only. ____________ | |

Did you restart the BOINC Client after placing the files? Otherwise these won't be recognized... | |
