Problem with tiny cache in MW
(Message 33804)
Posted 27 Nov 2009 by Bralle Post: Some numbers for you. Running quads on my 2 main crunchers. One quad needs 3 hours +- per core for one milkyway WU, with a total of 24WUs with work, thats 18 hours of work in total for that batch of 24WUs. My ATI 3870x2, which isnt fast compared to the 4000 and 5000 series, can do a WU in just under 2 minutes, with 2 cores that adds up to 1 WU per minute. now, with 24WUs in cache thats a stagering 24 minutes of work. Now, some of you say that we need that flow of steady WUs to return to generate more work, well, cant we atleast get "up to" a 3 hour cache on GPUs atleast ? or even better, full 18hours ? If a CPU uses 18 hours to complete its batch, a gpu shouldnt slow down anything by having a larger cache, times 4-6-8x. If the problem is not enough work, then I would like to know if its not possible to generate more work, 2-4-6x the current work ? or is this humanly impossible ? And stop using the "credit Whore" comments all the time, ofc credits is a big driver, but in the end, we want loads of work to do. We mainly here for the science. And its your job to keep us fed with WUs :) |

Posted 25 Sep 2009 by Bralle Post: Guess you have Crossfire disabled. With the newer drivers it's generally okay to run it with activated crossfire so both GPUs can be used. I was running both gpus on COLLATZ earlier. But dont work on milkyway. 2 WUs on 1 gpu currently |

Posted 25 Sep 2009 by Bralle Post: Running Boinc 6.10.7 with CCC 9.9 There is no "disable option" in CCC for this card, tho I can put cayalyst A.I to "disable - standard - advanced" This disable will make crossfire not activate, standard and advanced will activate it and start using 2nd gpu when running games. But I have yet to see the 2nd gpu active in boinc. :/ have also connected a 2nd monitor to check things out now, and still, gpu 2 is idle. CCC clocks the core from 850 +- down to 297 when idle. And it stays there until I start a game. |

Posted 24 Sep 2009 by Bralle Post: Running Boinc 6.10.7 with CCC 9.9 Have tried earlier versions aswell. Here is my problem : running ATI 3870x2, installed the latest application from you guys, started up boinc, and got some WUs to work with. 2 WUs was Crunching when I noticed that only 1 of the GPUs was running, CCC and rivatuner says gpu 2 is idle, but nr 1 working its magic on the 2 running WUs. Read up and down and cant see anyone with same problems. What can be the cause of this ? any tips ? //bralle |
