Posted 16 Feb 2009 by Exar Kun [HoloNet] Post: max_ncpus back to "1". avg_ncpus set to 0.25. If I keep the default value of 0.50, I have only three WU running at the same time : two optimized MW and one World Community Grid. With avg_ncpus to 0.25 I have four workunits (two for each project) Travis > thank you very much for your answer about the credits, it's a very good news. For maximum number of units per core, I can say that : with a Core2Duo and a HD4850 512Mo, I crunched 2000 workunits in 6 hours (with no other projet running at the same time, so the CPU wasn't at full use). So 4.000 workunits per core and day will be enough for this configuration (my computer is working "only" 12 hours per day or so, so 4.000 WU per core and day is the very, very maximum). I don't know how many workunits can be crunched with another model of ATI. Cluster > If I understand correctly, your optimization uses "only" one core at a time, is that right ? Is it possible to use more core, so we can use only Milkyway on one computer with more than one core ? Do you need something special to help you for your tests ? PS : during this writing I reached my 2.000 workunits limit - later than before, probably because I tried avg_ncpus to 0.10 ... |

Posted 16 Feb 2009 by Exar Kun [HoloNet] Post: avg_ncpus set to 0.1 max_ncpus set to 3 (core2duo) Seems to work very fine, the Milkyway units are still completed in 8 or 10 seconds. It's the same time when I used 0.50 core, is it "normal" ? Too bad we have the 1000 workunit-per-cpu limit, is it possible to send a request somewhere to remove this limit when using an optimized app ? This limit is now obsolete when you can calculate 3 or 4 times more units in a day with an optimized app. The only reason I'm moving a computer on milkyway is to help you for your excellent work on ATI graphic cards, but the credits are not very interesting ^^ THank you for this app, anyway ^^ |

Posted 14 Feb 2009 by Exar Kun [HoloNet] Post: How have you guys installed the BOINC client? Default options for me on Vista64, so I think I used the protected mode. It worked very fine until the 2000 WU limit. I earned 1939 credits in 6 hours. Only three WU went wrong during the initial tests, but it was my fault ^^ |

Posted 14 Feb 2009 by Exar Kun [HoloNet] Post: Works fine on my E7200 2.53 GHz & HD4850. I get about 300 credits per hour, with four workunits at the same time (Core2Duo). Thank you very much for this information ^^ I tried a few hours ago to (re)join my main project (World Community Grid), but I stopped when I saw "only" two MW workunits instead of 4 before ^^ But the 1000 Wu limit per day change everything ^^ Question : if the GPU app uses only one core, is it possible to use the other core for a CPU-optimized app ? Or use all the cores with the GPU ? |
