    I have a P4 2.8GHz that runs when I have a place for it. I liked it's output but, at the time, compared to my Socket A 2600+ O/Ced to around 2.15...

    Anything helps!! Go for it!! We need everything to beat RIT!!!!!!!!!!!

    I have access to a dual P4 Xeon 2.8Ghz machine (2c4t), but it's sort of, you know, doing important things at work. I'd be lying if I said I hadn't pondered it's potential PPD. For daily operation, I'd say P4s eat more power than they're worth. During a competition, the choice becomes more of a personal one. I'm already pushing the limit for power usage, so it's a "likely not" from me.

    No, no. You asked for it. XD
    Also, I'm kind of curious now.

    Assuming I have a 2.8 GHz Socket 478 P4, taken from this page, and CPU stats guessed from this page, we can take the 0.001992 points per CPU second, multiply by two 60s and a 24 to estimate 172.1088 PPD.
    I would have guessed something a bit better, but my 2Ghz Core 2 Duo Mobile lappy sits somewhere around the 400-600 PPD range and I'd expect that thing to beat the snot off most old P4s.

    Edit: Something's not kosher with the above. I checked an AMD FX 8350. The above formula gave me 224 ppd. Going off of "Average credit per CPU" instead and multiplying by number of threads, we get a more realistic 3122.4 PPD.
    Doing the same for the P4 above just gives 1.36 PPD, so I don't think Boincstats.com is completely accurate or "Average credit per CPU" isn't a daily average.

    tl;dr: Disregard everything I've said.

    Excel says that's 1832 average. Pretty sure that's WCG points, right? Divide by 7 gives 261 PPD.
    I think that's a pretty solid answer.

    That is more than your average figure's, above. Also, if you were to only include the days it ran for 24hrs, it would be a greater average, I did not run it 24/7, while I had it.

    My rough calculation, total points divided by, a close estimate, 223 Hrs, equals 115 WCG points an hour.

    divide by 7, for BOINC points, equals 16.4, per hour.

    multiply by 24 hrs, equals, 394 points a day.

    So, there you have it. PPD estimate for a single P4 2.8GHz CPU.
    :)

    At least according to the P4 I was running for about 3 1/2 weeks.

    No one has confirmed if this is what it is like for them also, but for a dual core I would need to set ncpu to 5 to get 3 wu's going.

    I just set up my buddies Athlon 5000 x2 back to <ncpus>2 because it ran one job at 43% and the other 2 at 14%, which severely slowed the work down.

    It finished three jobs running on stock cores in half the time it has taken 3 jobs to run to almost 50%. I will update later with the stats on my i5...

    Ok, over the past half an hour +, I have watched my i5 at ncpus 6 for a bit. Then switched to stock, 4, for a few, then to 5 and I am finding that 5, or 1 more, or 25% more, is running VERY well!

    Where 6, or 50% more, ran quite slow. About 4% less CPU usage per WU and the Boincmgr grew to almost 10% CPU usage.

    Whereas, 5 WU's, or 25% more, is around =< 2% slower (CPU usage per WU/ compared to stock core count run) and the Boincmgr drops below 7%

    So, ATM I am running 7 WU's on 4c/2t, with the i5 upped .25.

    Therein is my less than scientific analysis of an i5 3317u Running BOINC and an Athlon 5000 x2 running BOINC. (i5 on win8.1, Athlon on win7 Pro sp1)

    Looking at my 4820k, I am at 5700 ppd today which is pretty much normal. I might of just had some coincidentally high days. But I had a really low day over all too.

    Now if they can just get to my 64 pages of results. Has been running around 30, ballooned to 55 yesterday and is currently at 64.

    That is why I just reduced the value for ncpus to 5 on Darwin. It is a multithreading king, so it was to be expected that 6t would not work as well.

    Just took a gander at some results, and it really looks like crunching on my Galaxy S4 has been pretty useless. I got some errors, some timed out, and a few that actually made it as valid. I uninstalled it from my phone already and won't be revisiting it any time soon.

    It doesn't make much sense to me why some were invalid as my phone is running very normal setup without any modifications. As for some taking too long, it doesn't make sense to me either as it went all night and averaging at least 10hrs/day, probably more like 12hrs

    Whatevs, it was fun to try out especially for the Challenge :)

    225 pages with only 22 pages of Pending verification. Worse yet, I have 32 pages of errors on the Opty 6180 server:eek:. Kinda makes sense because it's production has downright sucked the last couple of days. Looks like CEP2 and MCM are the culprits, so I have removed them from my projects. I have also changed the NCPU's back to 48 last night and it seems to be cutting down on the error rate.

    So has a consensus been reached yet on ncpu? Should I add it to BOINC Config Utility or fuggedaboutit?

    Something went wrong with that stat 2 years ago. It was useful before that - my 4 GHz e8400 was in the top 20 as I remember.

    I found my 25 W fan pointing at my 2720QM just blow leaving it to run at 1,6 MHz (did 2.6 when it was new). The cooling arrangement on that laptop can be taken apart but I can't clean the fan. Time to protect my remaining hardware. I will leave my WC i970 on but the rest will gradually be stopped in a day or two.
