    Exclamation Moo Runtimes

    I was looking at my completed tasks on Moo's site and discovered some HUGE variation in run times. From a low of 2,300+ sec. to over 13,000+ sec. And the amount of time varies by date.

    Nexus (My Desktop):
    ID#- 297
    List: Completed Tasks

    Clocks
    CPU: 2.8Ghz (Stock)
    ATI 5830: GPU = 950Mhz / MEM = 900Mhz

    Projects:
    WUProp
    FreeHal
    MooWrap
    PG-PPS (Sieve)
    YoYo (Now set to NNT)
    Aqua

    Any ideas?

    Note: I just up'd the 5830 clocks to 1000/1000 (Which MW did not like).

    Edit: I put Odin (w/2x 4850) on Moo a short time ago and it completed its first wu in 4,141.21 sec.

    4850 clocks: GPU = 700Mhz / MEM = 650

    2nd Edit: WUProp Data on ATI Hd 5830 here.

    Re: Moo Runtimes

    Do you have one free core that is doing nothing. I've seen the same when I have all my cores working on a CPU task. So on my i7 I have 75% as the setting for "On multi-core systems use at most". With MOO it then runs 100% of the cpu.

    Re: Moo Runtimes

    F$, there are several things with Moo.

    1. The time shown in the "Run Time" may or may not be accurate. On single GPU systems I've found it to be close on dual GPU it may or may not be depending on the system.
    2. To get accuracte run time you have to open the wu record "Task" and subtract start time from end time.
    3. On a single GPU you need to reserve a thread for Moo. On a dual GPU you need to reserve a FULL CORE.
    4. You are running your wu on "core 0". On all my ATIs systems it is MUCH MUCH better to run on "Core 3". You set that in project preferences.

    You can run a benchmark that will show you how it will perform on each of your cores. Then use that to select the correct "core" in prefernces.

    1, Stop BOINC
    2. Call up the command prompt.
    3. Type in the path name of the executable "dnetc)1.02_windows_intelx86_ati14.exe -bench". So it will be something like C:\program data\boinc\project\moo wrap\dnetc.... . exe -bench
    4. Hit enter.

    The program will run and show you the speed of each core on your processor (relative only to Moo). In Project Prefernces that is the one you want to use. Makes a BIG BIG BIG difference in credits.

    If you do a search on the Moo forums using the executable name you should be able to find the procedure.

    Re: Moo Runtimes

    First, thanks for the feedback.

    Since the system in question is my desktop I have BM set to use at most 75% of processors. I tried running the -bench switch with dnetc_1.02_windows_intelx86__ati14.exe but no go. Then I tried the switch on dnetc518-win32-x86-stream.exe, Success!!!

    dnetc v2.9109-518-GTR-10092921 for ATI Stream on Win32 (WindowsNT 6.1).

    Testing variability might lead to pick one or the other.
    I changed the project preferences on the Moo site so now its wait and see....

    Re: Moo Runtimes

    See what happens when you listen to an old guy! I thought it was the ati executable but it has been along time since I did that. I'm glad you figured it out!

    Hahaha Very funny At least you got me pointed in the right direction, so thanks.

    Just to let you know, a couple of people posted the same suggestion on the Moo forum. So your not alone

    Good news. It worked. The elapsed time shown in BOINC Manager dropped to under 40 minutes.

    I should have realized something was off much earlier because the 5830 temps were around 59C before the change. Now it sits between 68~70C. Of course now my room is slightly warmer..........

    Also, I had to drop the 5830 clocks back to its previous settings. Windows was acting a little funny and when I tried playing World of Tanks I started getting VPU recovery errors.
    I may try updating CCC but I am leery of what AMD has been putting out lately.

    Anyhow, thanks again for the help.

    Re: Moo Runtimes

    Is this the reason for the differences in credit? I have 4 machines that get on average 1,600 credit per wu. I have 1 machine that gets 6,000 per wu? I checked and I'm not alone as far as this goes. If I could get them all to get the 6,000, I could increase my output by 375%. Any ideas? This would really help the team to figure it out. Run times don't seem to be it. GPU 4800, 5800, doesn't seem to matter either.

    Re: Moo Runtimes

    CB, they have different sized wu depending on the speed of your GPU ... tiny, small, normal, and huge. Cards like the 58/69 series get the huge wu that pay 6k. Nvidia and slower ATI GPUs get the 1600, and I'm guessing CPUs get the "tiny" ones and I have no idea what they pay. If you look at the "Server Status" you will see what I'm referring to.

    Re: Moo Runtimes

    Thanks for the info Bryan. I made my observations actually from looking at some of your machines running the 5800 cards and getting a mixture of both 6,000 and 1,600 credit work units. Didn't realize that they were doing that. Oh well, I can wish can't I?

    Re: Moo Runtimes

    Huh....could this be why my credit is all over the place? I've got a single 5870 on it, and some days I get really good credit, and other days I'd be better off crunching Collatz!
