I feel , because I should have proposed to all TeAm-racers to set their buffers high enough ...

Setting a large cache-size doesn't help due to WCG having a max task-in-progress of only 400 tasks/GPU.

[petrusbroder]

400 tasks/GPU = (at 10 minutes/task) 4000 minutes crunching time = 66,6 hours of crunching = 2.78 days of crunching.
That is more than the default set in BOINC, which is 0.5 days of crunching. If each task takes longer, then you have more time ... I have two GPUs/computer (=800 tasks) and I have still not run dry of GPU-WUs ...

Thus setting a large cache helps - not for the full 5 days, but more than the default.

As you all can see those who have set the default cache have dropped quite a lot in their production.
How else do you explain the decrease in production of by 30 - 60%?
biodoc, Neurodog and petrusbroder either had sufficient WUs in the cache or did not use GPUs ...

Name __________ production ______ production
_______________ 2012-11-19 ______ 2012-11-21
Ingleside ______ 709,190 _________ 297,103 = -58%
petrusbroder ___ 576,177 _________ 540,767 = - 6%
ZipSpeed _______ 479,394 _________ 352,466 = -39%
biodoc _________ 375,204 _________ 375,924 = +0,2%
blckgrffn ______ 273,656 _________ 143,774 = -47%
Kaebu __________ 228,926 _________ 177,143 = -23%
WildW __________ 152,835 _________ 107,181 = -30%
Neurodog _______ 136,179 _________ 136,467 = +0,2%

Oh, BTW, less than 4 hours of the race to crunch!

I can push out 2 more WUs for the TeAm.

Starting to manually dump completed work. Won't be able to do it unfortunately for my rigs at home.

400 tasks * 10 minutes/8 tasks = 500 minutes = 8.333 hours.

8.333 hours << my 1-day cache-size (+ 1 day additional, but this isn't normally filled in v7-clients).

If you've got a fast GPU, you can use app_info.xml and run multiple HCC-tasks on a single GPU, this can utilize GPU more fully and can therefore greatly increase production even if you runs fewer CPU-tasks.

Taking a look on the result-log, was actually averaging 1462 HCC per day during the race until ran-out of work, meaning 400 tasks was only 6.6 hours. This on an Amd-HD7950 running at 900 MHz (default overclocked).

Isn't that like 60,000 ppd?

It seems to be closer to 80k PPD, not surprisingly my production dropped with 58%.

[petrusbroder]

I agree.
Depends very much on the system you have. None of my GPUs is as fast the Amd-HD7950 ...

That's freaking nuts. I was just ball parking it - when a dedicated 2600k gets 5k ppd, that's a pretty big difference in points earned.

I wonder how they'll evolve their system to keep CPU/GPU work credit balanced to keep the CPU crunchers in the game...

Yeah, that's how the EVGA team overtook us last week but because of the race, we took back our lost spot.

Thanks for the stats and great race team!

Cool, so I can wind down one of my extra WCG crunchers for now? Trying to save a little on the electric bill.

Edit: Not really planning on participating in the F@H race. Kinda got bored with F@H.

I'm actually going to wind down all but two of my BOINC crunchers, my A6-3670K doing WCG/HCC (my HTPC, keeps my bedroom warm in winter), and my E-350, which is doing Correlizer.

Going to let my G630 idle too, maybe.

Rest while you can because it won't be long before the F@H race!
