Thread: Primegrid Challenge Series

  1. #1

    Primegrid Challenge Series

    OK, guys, I was the only person who put up some numbers in the last Challenge. This time I want some help.

    Starting Nov. 11, 2010 at 1800 UTC (11am Pacific) the next Challenge begins. It only lasts for 24 hours, so we need everyone to be on time. Here's the link, http://www.primegrid.com/challenge/challenge.php.

    The only work that counts is work downloaded after the start time and uploaded before the finish time. No stockpiling work and dumping. The Challenge project is the Sophie Germain Prime Search (LLR). These WUs take approximately 21 minutes on a fairly new machine. No GPU work units.

    Come join me on Nov. 11 and represent Free-DC!!

    Great timing, Thursday to Friday. It'll get my support. I see that one of the projects supports Cuda. I'll switch my Nvidia cards over tomorrow and give Laurenu2 another chance of catching me at Milkyway. That should help move the team up through the ranks some. Anyone have any idea how much credit a GTX260 makes?

    You will need to keep a sharp eye on that cuda app. People have reported a lot of errors with it and it may need a special file.

    Don't be an hour early. 10am Pacific, 11am Mountain, 12pm Central, 1pm Eastern and something else everywhere else.

    It's only 24 hours, so let's show some team spirit!!

    Remember, only those work units DOWNLOADED after the starting time and UPLOADED before the ending time will count. DO NOT Stockpile a bunch of work prior to the starting time

    After 3 hours, it looks like it is just 3 of us verses 564 others.

    The team ia at #26 with 2707.29 and moving up.

    The individuals:

    Bok at #256 with 384.32
    outinder at #185 with 563.66
    Bigred at #58 with 1759.31


    We need more

    Lauren where are you?

    Alrighty then,

    The Final results for the Challenge were very good.

    Free- DC came in 23rd out of 221 teams.

    BigRed was our flag barer coming in at 46th

    Outlnder followed at 172

    And Bok came in at 324.

    I think that was all that participated from Free-DC, but if I missed you, please chime in.

    This was a good showing, but I know we can do better. We did beat Ars (42).

    The next Challenge will be the Winter Solstice Challenge Dec. 18-21. Get ready!!

    Am I mistaken or will the next challenge let me use my Nvidia GPUs?

    If so,I've got 9 GTX 260s that should add a little firepower.

    Ok everybody the Challenge is coming up soon and we need some help. Last one there were just three of us. This will basically be a GPU slugfest but CPUs are appreciated too. This project Really likes Nvidia cards. ATIs are OK but they are difficult to get running. And before you say my card is too old to run Cuda applications here is a list of cards that are known to work.

    The only issue that I know of is that you need .NET3.5 to make it work in windows and the times above are outdated as the new WUs are larger.

    Ati cards are a completely different story. They are not as fast here (my GTX260 out performs a HD5850 here) and they are a PITA to setup. The require an app_info_xml file at this time but the project is working on it.

    Just in case anybody is interested, we've moved from #50 to #31 in RAC in the last 24 hours. All thanks to a team effort.

    I think you may well be passing me in the next few days

    We need to get Lauren's cards running it too Looks like they are trying hard to get the ATI cards running natively and Fermi class nvidia cards are working out the box now...

    Luc is running a single Fermi and the results are awesome.

    I've still got four Nvidia machines to get switched over, hopefully by the end of the week.

    I'm going to wait and see if they get the ATI situation straightened out before the challenge. If they do then all of mine will be there too. I believe Lauren is going to do the same.

    If everything works out then the four of us should be kicking out well over 3 Mil. a day. Throw in what everyone else is doing and we should do well for the challenge.

    I've actually got a couple of other cards, just no active machines. I'm sure I could get a few running and just use the GPU's on them. Maybe

    Luc's is from a single Fermi ?? Wow, what is it ?

    The more the merrier.

    Luc's is a GTX470 and I've sent a special request to Santa for one.

    We're now up to #24 for RAC.

    Hopefully I'll get at least two more boxes converted tomorrow.

    Things seem to be lining up well for the upcoming challenge.

    Bok is cruising right along with his Nvidia card.

    Lauren is getting his ATI firepower setup.

    I've got my 9 GTX260s, 3 HD5850s, 1 HD4870 and 1 HD4850 munching right along.
    I've got 3 more ATIs to setup tomorrow and I hope my other one is back from repair in time.

    Between the three of us and everyone crunching on thier CPUs, I figure we should be able to do about 3 Mil. a day.

    To anybody running a Nvidia card on another project, you will get about 3 times the credit here. If you're running an ATI card and need help getting it working here, just ask. If I can get Lauren through it, I can help anybody. ATI work requires HD48xx and up.

    Currently we're at #20 RAC and #37 Total credit. The next team we should pass is Russia.

    But 3 of the do not like the project
    they do all Error WU's so they will stay on MY
    I could throw in 300 Ghz of CPU power
    For that weekend to

    As I predicted, we hit 3 million yesterday.

    And we passed Team Muskateers.

    Next up, US Navy.

    HD4870 and up run just fine but you must have .NET 3.5SP1 and the Catalyst 10.10 (apps) driver installed. Please note this is not the normal driver but it is the one required to run OpenCl. Also the Cat 10.11 drivers have not been tested With OpenCl 1.1. If you are running a HD4850 or below you will need an app_info.xml file to keep it from erroring out all the WUs. I have one if you need it.

    Ok here is the step by step guide,
    1. Attach to prime grid with one box.
    2. Go to your account there and verify you have the 1.4.838 driver (for XP32bit)installed. This is important as this is the apps driver which includes support for OpenCl. The regular driver does not have this.
    3. Change your preferences so that only the ATI gpu is checked and only PPS sieve is checked.
    4. Let Boinc download some work and then shut it down.
    5 Copy the following and paste it into notepad. Save it as app_info.xml

    6 Find the Application data folder. Under it should be one for Boinc. Under that one should be one for projects. Under that should be one for Primegrid. In other words:application data\boinc\projects\www.primegrid.com. Copy the app_info.xml into the Primegrid folder and restart Boinc.

    This is only necessary for HD4850 and below, Everything else works without it. Make sure .NET3.5SP1 is installed.
    Let me know if you need more help.

    Thanks ... will give it try later in the week. I did get 1 of the GTX-260's and HD 5850's running for a short test. the HD 5770 error'ed out but i think it has .net 4?

    Great. More than likely the problem is the driver. I can't tell though because your computers are hidden.

    They are visible now, I think it is a corrupt driver install. I noticed this morning when attempting to get it to run again tiny orange dots started popping up on the screen, they go away as soon as I shut boinc down. ... will try to download and re-install this evening.

    The driver is the correct one but it might be a corrupt install. I believe from your description it may be overheating. Download and run GPU-Z and check your temps. It could be as simple as blowing out the heatsink, a failing fan or a power problem.

    I got one of the HD 4850's running with the new 10-12 driver released today w/o the need for the app_info file on Win7_64, now if it will work on XP_64 I'm in business. I will try one of the HD 5770's with this driver too and report back.



    /edit/ On the 5770 I at first thought it was another failure ... 1st 3 wu's errored after only 3 or 4 seconds, but the fourth one is still running. checked the failed wu's and all have multiple failures.

    Next question, how are cpu's like on this project, worth the effort?
