    Ok, I know, it's 15 days early but, I made the previously mentioned changes, just now. I will know more in about two hours, as a couple of FA@H WU's finish up. Meanwhile, I did get one additional CEP2 WU as soon as I forced an update.

    By this time, or sooner, tomorrow, I should know if the changes will work for me. WOW, while typing this, I got another CEP2 download!

    Anyways, I will probably keep it, if it works, and be running full speed by the time these challenges roll around. Actually, I might throw a few SNTS's in once it gets up and rolling. I don't have any of their badges. Once we get closer to the challenge, I will re-opt out for the durations.

    Yeaaaaa, THAT'S the Ticket!

    :D


    P.S. I now have three new CEP2's, since the changes!

    p.p.s. Credits today 1,137.63, that's pretty good for my little lappy topper!!

    I'm in.
    Have changed settings few days ago but received very few CEP2 WU's. Time to stop other WU's for the sake of CEP2.

    Edit : Identified the problem - Minimum download bandwidth for CEP2 is 63.48 KB/sec and i am providing lower than that most of the time when it connects to the WCG server.

    Another CEP2 binge?

    Why not!

    Count me in.

    You can run CEP2 exclusively if you like but you can also run any/all of the other projects....this is an all projects challenge. The CEP2 challenge is scheduled for 10/6-10/14.

    That said- I've doubled my CEP2 load on all of my rigs with decent internet connections and will keep those settings or go for more CEP2 work until at least the end of the CEP2 challenge. :)

    Maybe it's just me, but CEP2s seem to bring me more points per minute than any other WU.

    These days, that would be true to my boxen, no doubt. With SN2S bringing a little bit under what CEP2 does and FAAH giving downright bad points.
    But, there's always a huge BUT. CEP2 tends to error out en-masse every once in a while, wasting a lot of CPU time this way; sometimes over 90 hours of CPU time gets wasted at once on an octacore.
    Because of that, SN2S produces more net points than CEP2. FAAH is still behind CEP2, even after considering those CEP2 errors.

    In fact, I never get computation problems with CEP2 (I had issues with ClimatePrediction and GPU work for DistrRTgen and Einstein@home for a bit though, but that's not WCG related). CEP2 WUs are hot however (max sys load by BOINC being lowered to 90% makes matters do-able though), and not friendly to all networks so I can still imagine they are not everyone's friend.

    Tonight, I've passed beer and gone straight to vodka, enjoy the good stuff! :toast:
    Can't help humanity if you haven't helped yourself to some good vodka :laugh:

    OT: is CEP2 more cpu stressing? I hope I don't have to drop my CPU OC!

    Ok I registered and joined the techpowerup team. Downloaded that and everything, it started "say no to schistoma" automatically. Temps are hanging around 35c so thats fine. Have it set to 80% load on CPU

    You're running at all defaults now- keep it running like that for awhile and...

    A- watch your temps

    B- watch out for errors in the work units

    Switch to advanced view if you haven't done so yet

    Thanks for joining up! :toast:

    WCG's website lists average points per hour of runtime for each project. I was actually just working on sticking them all together earlier today.
    Pulled from here.
    Code:
    Project	Avg time/WU	Pts/wu	Pts/hr/cpu
    CEP2	07:19:35.00	1090.83	[B]148.89[/B]
    FAAH	06:38:13.00	595.09	[B]89.66[/B]
    SN2S	03:53:56.00	624.05	[B]160.05[/B]
    CWP	03:24:17.00	433.47	[B]127.31[/B]
    HFCC	06:39:07.00	792.87	[B]119.19[/B]
    Beta	03:58:19.00	534.26	[B]134.5[/B]
    Your mileage may vary, of course.
    Surprisingly (and sadly), SN2S gives the best points/hr. No magic increase in PPD for us by forcing to one project. In fact, if you switch to pure CEP2 for the challenge, expect a drop to about ~93% your normal PPD.

    Hmmm... the times I have SN2S on all cores saturates my CPU much better than CEP2 does. CEP2 underutilizes my CPU, so it's only 90-95% loaded. And CEP2 makes my CPU run a little bit cooler.


    So I suppose it's YMMV when it comes to CEP2, kekeke...


    EDIT: Count me into the challenge, too! Though, only for "sportsmanship"; don't include me into the prize drawing. :toast:

    I thought CEP2 typically ran hotter. Am I thinking of CEP1?

    A 93% drop in PPD seems unreasonable--that would be dropping your output to 7% of what it was initially. Maybe a drop to 93% of what you were doing ;)
    Yes, they do. On my laptop, CPU power usage increases by about 7% and temps go up about 5C. Given that it already does 82-85C running other projects, I never run CEP2 on it b/c that runs it so hot that it thermally throttles down to 1.1GHz at least half of the time (where obviously output isn't so good)

    I.. I.. yes.

    One of my machines has an AMD E1-1200 in it. Estimate time for one CEP2 WU is 100h 11m 48s. :shadedshu
    (It's a work computer. They gave it to me as an "upgrade" over my 1.8GHz C2Dm laptop.)

    CEP2 wu's are tough on a rig sometimes. My opinion would be if you can't finish a wu within 24 hrs then consider adjusting the profile for that machine to avoid them. I ran into issues with Phenom II's getting errors and invalid results with them so I avoided them most of the time. The FX's and i7's currently in my rigs seem to do fine with them atm.
