Hmm using a whole lot of CPU on the 5970 & The New Box.

[Mike029]

Here is the problem. I added the 5970 to my gaming box for now and this is what the times look like.

What do you think? Why so much CPU?
I have only 6 threads running as I have the 5970 and a 5870 in the same box should I free up another thread?
Could I get away with the 5970 and a GTX 570 in the same box if the box has only a AMD x2 BE processor or will I choke the gpu's?

Is this Moo you are talking about? If so, the faster the GPU, the more CPU is needed to keep up. With my dual 5870 + i7 920 (OC), I need to reserve two threads (1 whole core). Anything less, and my task run times climb.

Yeah, sorry, it's Moo. I'll leave three thread and see what happens. Thanks Z..

Did you run the Moo benchmarking to discern which program core Moo should use?

That should be done too, to maximize credits. But the need for allocation of CPU doesn't change with the "core" (aka app) selection.

Hmmm, OK. I thought the proper Moo "Core" (not to be confused with CPU core) improved CPU efficiency, thereby reducing the percentage of CPU resource allocation?

The better the core speed, the better the load on the GPU, and the greater the need for CPU to keep up.

[Mike029]

Ok, How do i do this? I know there was a whole post on this and it seemed a bit difficult but I'll give it a try. I'll try it tomorrow on my cruncher.

Duh... Right. I knew that! Really, I did.....

That sent me to Philly's Blue screen Thread.. You trying to tell me something? *Puts on my best Bronx Accent* I can do it pretty good ask DrPop.

Yeah, I have fixed it. Sorry.

Here is anotehr strange thing happening, It says I'm finishing wu in 1500 to 1800 sec. I'm watching the wu's and they are finishing in about 10 to 12 mins. Below the reporting time. Another thing I noticed is that the last 40 to 70 sec. a wu crunches is completed by only one or the three cores. Perhaps the counter take the number of seconds it take to complete a wu and multiplies it be the three cores?

Thanks F$!!!

[Mike029]

That was very easy and says Core 2 is much faster. Switch was made. Thank you again F$.

There are two different times reported. Don't confuse run time with CPU time. The better the GPU apps will have a smaller CPU time vs. run time.

Also, there are two different tasks (maybe). There is a longer app for 58xx+. Or was that DNETC? I don't recall. So make sure you are comparing apples to apples.

What do you think about these run times?

The is my machine (1st gen i7-920 w/ dual 5870, and only 6 threads (75%) crunching): http://moowrap.net/results.php?hostid=3854&offset=0&show_names=0&state=3&appid=

It looks like the times are about the same. And you have three GPUs?

But I notice that last task took way less time and paid about the same. Was that perhaps the first one after you reserved three threads?

With the 5970 and depending on the phase of the moon etc. the time reported is incorrect. Open the wu record and look at the start time and stop time and you will see the actual time to finish a wu. I always had this problem (reporting double time) on my 5970s.

Last week I crunched for a friend and I had never had the new 6990 on Moo. When I got it moved over to his account it was reporting 780s to complete a wu. 2 days later I detached and moved it under my account. Now it reports 1560s (double) the time the wu record says. Credits per day are the same but for some reason it doesn't report the right time. Same machine and same card with same credits per day. Go figure.

[zombie67]

So, if I understand what you are saying, the time reported means nothing, and mean nothing with regard to credits awarded per task. So look at your credits/day to see if you are doing better/worse. Right?

[Mike029]

Yeah, looks like Moo has sorted it out. Mopo times are at 700 to 800 range now. All good.

This is were i find boinctask to be handy... it records the time the wu takes under history and its awesome since i want the info now it gives it to you... What i have found is if you use your computer and it suspends the task the time are all over the place with the project website so dont know if its calculating the wait time as well or just delays in restarting the project or some sort of estimated time or i have forgotten how to use a calculator to find the minutes =)).. confuses the hell out of me but once i started using boinctask i can see it all instantly.. being able to compare computer to computer or video card to video card after several wu to get a base line is very nice... give it a try just make sure to minimize it once you done looking since it graphic intensive when using gpu for crunching...

Yes sir at least on multi GPU boxes ... it is always correct for a single card. You can open the wu record as I said and get the start time and stop time and you will find that the reported time is 2x or 3x(depending on # of GPUs) higher than the REAL time. I don't know what causes it because like I said I attached and ran for someone else and the reported time on the 6990 was correct. When I moved it over to my account then the time was double what it really took. Go figure!
