more then likely it will give gpu crushers high rca till they make changes then it will norm and then you guys will have a low rca

Message 839306 - Posted: 12 Dec 2008, 19:42:31 UTC - in response to Message 839287.  

just to give you guys a hint on the beta cpu time to do one wu on a 260gtx is
gpu 168.5 sec not min or hours
gpu 68 sec not min or hours
gpu 126.5 sec not min or hours

norm time on cpu is 3 hours

=) i like this when well it hit main steam any time frame

ps: given the app uses .o3 cpu well the final ver have more then 2 apps running at the same time given that it only uses 10% of my gpu power on a duel core cpu





Incorrect..

Those are CPU Seconds used in crunching the unit. (Note the work is on the GPU and only uses the cpu to feed them when needed)

I was trying to time them last night.. but the two i did varried.. i dont have any firm data on average times (Using 8800GTS's)

So dont get your hopes of super RAC monsters yet..

look at this gpu beta ones
CPU time 145.5313

Validate state Initial
Claimed credit 68.5024687836731

those for norm cpu ones

CPU time 15592.39
Flopcounter: 15879586159931.861000
Validate state Initial
Claimed credit 45.4154080963371

so it is by far faster about same flops in a small % of the time
the time listed is from the start of the wu to the end of it i also have a nv 260 oc vcard 196 cores

how long actually did the WU take to crunch?

The two WU's i ran both came back at 68 Seconds..

They surly did not actually take 68 seconds to crunch.. that's what im getting at.

By far I'm not very pleased with CUDA. Not to mention some keyboard/graphical lags, my Q6600 with optimized applications processes still faster.

EDIT: and another CUDA MB took 25:11. Not too bad.

The S@H-Beta-GPU-app use all Cores of the GPU simultaneously?


Why only Nvidia (CUDA)?
ATI have the AMD Stream SDK (System Developer Kit).

I don't have a SETI@home-Beta account.. so I can't post there..
I'm only little curious and would like to support.. :-)
To now I have only a 6200 in my rig.. ;-)

SETI@home beta CUDA requires minimum nVidia Geforce 8 series with 256 MB video memory. ATI not supported yet. Don't know why, just so. And yes, I think, it uses all graphical cores (for one task at once) on my GPU, 112 cores that is.
In addition to this info, to join SETI@home Beta Test you need attach to project using http://setiweb.ssl.berkeley.edu/beta/ in BOINC 6.4.5, provided that you installed CUDA 2.0 drivers before.

ATI not supported yet. Don't know why, just so.

ATI will be supported in a future version of BOINC, their developers are working with the BOINC developers and projects to port applications. This will take several more months though.

Because we all want the fastest one.. ;-)

In future, the speed of available apps for Nvidia and ATI would be the same?
Compared with the same speed, Cores and RAM of the GPU.

Maybe an AMD CPU-Mobo-GPU-combi would be better (than Intel) because of the better AMD CPU-GPU-performance?


EDIT:
CUDA? What's about PhysX? :-D
[PhysX would run on nVIDIA and ATI..]

Please could all contributors to this thread read Matt Lebofsky's note in Technical News today (message 839285):

For the record, I have *zero* idea what's going on with the CUDA/SETI@home beta project, except that it now exists and I was just merely pointing out its existence. Please forward all comments/questions to the beta forum, which I assume is being read by the beta developers. Sorry for any confusion.

and act accordingly - i.e. transfer all comments/questions about the Beta Test application to the Beta forums.

Yes.. O.K. .. I know.. but I don't have a Beta account.. ;-)

I'm little curious about the crunching-time with the GPU.
[The CPU-time is not well to measure the GPU-crunching-time..]

Where I can find posts about this topic?

Because about what I read..
The CPU-time is not for to measure the GPU-crunching-time.
Because the CPU support only the GPU..

So the CPU-time say only how long the support was..

Yes.. or no? ..I don't know.. ;-)

So how you can measure the correct GPU-crunching-time?


BTW.
And you crunch with an idle Core of your CPU?

Hi, so far the only way I've been able to find out how long the crunch time is would be to check the log for start and completion times of the tasks.

To be able to use the idle core you can check out this message

Also we really need to keep discussion of the Beta apps at the Beta site.

Have you got enough testers having a play or could you do with a few more yet?

Give it a go, seems to me they have too many when there's no more work.

The current Beta is Windows only - you'd have to compile your own.......

Is the Windows side debugged enough to be worth adding a whole new rat's nest into the fun?
