    I don't think I've made my comment to say I wouldn't turn down most prizes. Been running pretty much full CEP2, but have seen a bit of a drop in PPD the last little while.

    I had one of my rigs off due to heat, but it's back up now for the competition :)

    Sorry for the delay, I kinda missed this post. Sorry... [​IMG]

    The most reliable way to see if things are really working, is:
    open the terminal and run the uptime command. You should see something like this.
    Code:
    vinis@g44:~$ uptime
    12:18:57 up 15:53,  4 users,  load average: 8.51, 8.92, 9.05
    
    If Your [load average] / [core count] is less than one (i.e. less than 48 on a 48 core machine) that does mean it's not running right.

    There is a thing with CEP2 WUs. They take quite some time to "boot up" - when they are started / resumed they can spend several minutes reading / writing data to disk. Which means sitting on IO-wait most of that time. Looking at CPU load it looks as if it's hardly loaded at all during that phase.
    With 48 concurent WUs, I believe that can last for quite a while, especially if it's on one disk. My 8 sharing one HDD and its IO capabilities last over a minute, sometimes more, to "boot up". So Your 6 times more could take a while, I believe.

    Also, here's the screeshot You asked for:

    Well I had a great night and turned in nearly 50 completed/valid wu's :pimp:

    However, this morning is not so good.... we had an area-wide power outage so the 3 rigs I have set to 100% CEP2 are sitting in the dark atm :( :banghead:

    Power is expected to return within the next hour or two. I likely lost progress on most of the active wu's when the power went out but hopefully it won't be too much :shadedshu

    Sorry to hear about the power outages, Norton.

    Meanwhile, I've got several dozen more CEP2 WUs that error'd out.

    My dad's colleague asked me to recover data from his borked up usb flash drive.
    That involved a lot of "disk" I/O. And as I already mentioned a few times in summer, high I/O load on [any] disks + CEP2 = they freeze up for several minutes and error out.
    That's what happened today. Grrrrrrrr

    Hopefully it won't last too long... I'm at work atm but my wife is there sitting in the dark and not too happy about it :shadedshu

    ** UPDATE**
    Power's back on- now just got to get home and check out my rigs :)

    FYI- looks like we made an impact on CEP2 already (see pic @ bottom of Post #2):

    http://www.techpowerup.com/forums/showpost.php?p=2985486&postcount=2

    Contribution of CEP2 vs all projects went up from 6.9% to 7.3% (i.e. up over 5% overnight) :toast:

    Just dumped a bunch of FA@H on one rig to get to the CEP2 projects lower in the queue. I noticed that my 2P Xeon is past the activation window, and I'm out of re-arm attempts. It'll go til it chokes.

    Got 22 cores/28 threads all back and running CEP2! :toast:

    The power failure caused a HDD issue on one rig (chkdsk found/fixed the error) and had to do a CMOS reset on another but everything's running fine now :)

    Thats fine with me. I'd say if you're in Canada or Mexico, if you split the shipping with me, then we can work that out. I'll PM Chev and let him know to update the OP. The mouse really is awesome!

    Send I promise I won't delay this time in shipping it out :eek: ;)

    Weird, my main pc rebooted again just now, the 2nd time since I've been home and the 3rd time today. :mad: These last 2 times, I got the clock_watchdog_timeout bsod on Win8, which is reportedly CPU related.

    So I just dropped the OC 100mhz, now down to 4.4ghz, so maybe that'll do it. I'll leave it run again all night, maybe check on it half way through the night and see if it holds up. I'll be checking WCG again for errors. I did earlier and it looked good with valid results, but I hope these last reboots don't mess me up :banghead:


    Update: I checked it this morning and it seems to have remained solid throughout the night without rebooting :) so apparently it was a cpu issue. It looks like my CPU is perhaps degrading a little bit. It can only mean time for an upgrade! :laugh:

    Update 2 (since no one seems to be posting lol): pc ran fine all day, no reboots at all. I haven't checked WCG yet but I will to ensure solid results. However, my second gpu seems to have stopped working. :mad: it shows up in device manager with a yellow triangle, sucks. Installed new driver and seems to be better in Device Manager, no triangle, but I haven't tested it in game yet. Will do later

    @manofthem- sucks that your rigs are giving you problems :banghead: hope you get everything worked out :eek:

    On my end I think I'm maxed out on my CEP2 only rigs with 140 CEP2 wu's turned in today (120 valid and 20 more pending validation/verification) :toast:

    Rigs are running a few degrees warmer and just a bit sluggish but so far so good.

    Meanwhile, mine still error out a whole friggin' lot. Most on my "main" box - on other boxen they error out much less.
    I investigated it and I suspect the cause. And if I determined the cause right, it would mean SOL. As I can't do anything about this particular reason. Aww well, just gonna hope luck smiles on me and make the WUs behave better during the challenge.

    Try backing your ram frequency down to 1600 on your main rig... not sure if it will help but it's definitely worth a try and it won't hurt performance very much ;)

    Unfortunately, that won't help.
    I already found where the problem generally is. It's not related to RAM.
    I can't "fix" / change anything related to that general field. I also figured because of that, there is no use digging more to find the exact thing causing it if I can't change anything there in general. I could do it just for the sake of it, but that would mean provoking many more WUs to error out. :shadedshu

    If I would completely leave my main box alone for the time, the error'ing out rate should fall to the rate my other two boxen have. So I will do that for the time being.

    over & out. lol that sounded cool, huh?

    Thanks, I think it's all good now. GPU2 is now working, but with the new driver card2 runs 100% all the time, unless ULPS is disabled. So I did that, rebooted again, and I think all is going fine now.

    Back to crunching, and no unexpected reboots :D Everything should be all good.

    Sounds like you're sailing nicely and smoothly! Glad to hear, as we need rigs that don't have issues, since some of us are having issues! :laugh:
