Sten, Are you running lunatics on your computer?
Im wondering if I went to stock aps on my I7 920 rig if my RAC would go up?

Yup, I'm running lunatics "anonymous platform". I believe if running stock, the RAC will indeed go up, but the production rate will fall :-)

Crazy eh?

Sten after you level out, Will you do stock apps and see what happens? If yuo choose not too, I would be willing to try it on my I7 920.

No, after I level out, I'll go for a test with the Non HD5 ATI MB app. So, feel free to try out the stock apps.

Sten I have set no new tasks on the I7 920. It will take a few days to clear out the work. And then uninstall Lunatics.
Would you prefer I open my own test thread, Or can I post on your thread?

Just to save some time on testing I would stress that GPU stock and opt are quite close by performance, especially if stock app (it's slightly outdated opt GPU app actually) will be tuned a little with more optimal for fast GPU params.

So one could infer results of such testing perhaps.
On CPU side we have bigger discrepance in performance, but using stock AP I would call torture and torture forbidden by international law :DDD

We're not gonna fight them. We're gonna transcend them.

I think for the sake of the sanity of the participants on the board (that all knows what we're talking about) it would be better if you have your own thread for the stock test :-) Go for it James, that test should be interesting indeed.

Ok then, I will start my own thread. That way folks wont get confused of who is doing what.

I am going to torture myself and do MB and AP on the CPU, Plus run MB on my GTS-250. I want to see if there is any RAC advantage to run without op apps. But I might try running just MB straight up after I see what happens.

The hard part will be getting an average RAC for this machine. The stats graph looks like mountains and valleys. You can definatley see when we run out of AP work. I just might take the high and low and do the average.

So a few more days untill I clear my cache, And then I will open my own thread.

Sten, Thanks for doing this test. You have inspired me to do my own.
I still say you will level out at 8,000.

I've been doing a test myself Sten with this old setup that I have a thread on (and just updated, so I'll just quote my latest update here if you don't mind).

Update.

Well after almost 8wks of this test the highest RAC I've seen so far is 10,800 while mainly doing AP's (it's down 1000 atm due to finishing up a lot of MB tasks), but that's nowhere near the 24,000 RAC that this hardware configuration use to get doing MBV6 alone.

Cheers.

Keep up the good work.

Cheers.

I pull the numbers from statistics_setiathome.berkeley.edu.xml using a .bat and average them to get my average RAC. So it spits out "Host: 5837483 Average: 8030 for 58 days"

I will take your advice and run 100% MB. Then when stable try 100% AP, running just stock apps.

By the looks of my cache I still have at most two days to go.

I see what you mean by CreditScrew. Definitely feeling it here.

I'm not sure though what this experiment should prove or disprove.
Lets outline this to make it more interesting.

It's said, that CreditScrew should pay equally for equal work done.
Also it's said that the "master copy" is stock app. Also we know that looks like only CPU stock app involved, GPU gets screwed credits always no matter opt or stock.

So, if at least some of postulates of CreditScrew are fulfilled one should not see difference in average RAC running stock CPU MB and stock CPU AP.

Looks like you want to test this statement/prediction.
Well, Eric tested this on beta (and even on main?) server-side AFAIK, but case-study on particular host will be interesting too.

So, prediction is - no change in RAC. Will see ? :)

scaling. best stock MB is AVX, best stock AP is what, SSE2?
higher SIMD, less credit, if you want it put simply.

but do by all means run an experiment. Data is always good.

The implementation of CreditNew does not match the whitepaper.

over and out

You all raise some great points. Im heading to work now, But I will prepare what I want to do and maybe try it in 3 steps. When I get home tonight.

@ William- Would you say Stens idea about just renaming the App_ config.xml file to another name untill after my tests are done is a good workaround?

...

Stock CPU AP has no SIMD at all.
