http://boincstats.com/stats/project_graph.php?pr=milkyway quotes us at about 1.61 PetaFlops. Now, I am taking this number with a very very large grain of salt, but still ... 1 petaflop is damn impressive. With some sloppy conversions, we are looking at about a quarter million cpu years.

If that doesn't cause you to pause, read it again and think about that.

anyway ... Carry on.

Thanks for getting back to us. Looking forward to the writeup.

Don't tell anybody, it's a secret. Gosh.

After installing 10.1, boinc was crashing due to memory access violation. Logs showed it was CAL related. Rolled back and everything was good. (Had a similar problem with GPU-Z which seems fixed as well). 4850,275,windows 7 64-bit.
6) Message boards : Number crunching : NVIDIA GPU Bug? (Message 35686)

Hi there,

Take a look at http://developer.download.nvidia.com/compute/cuda/2_3/toolkit/docs/NVIDIA_CUDA_Programming_Guide_2.3.pdf. Page 109 out of 145. You want Compute Capability >= 1.3.

The document shows you picked up cards with 1.1.


For ATI cards, refer to: http://developer.amd.com/gpu/ATIStreamSDK/ATIStreamSDKv1.4Beta/pages/ATIStreamSystemRequirements.aspx
(superscript-1 Does not support double precision floating point operations)
58xx series should all support Double Precision.

Thanks.

(Could we create a sticky about what cards are supported or put that information on the front page?)

Oh I know, I would like to use 3 GPU's without taking out a CPU task. My system crunches only Milkway. Cheers to future stability.

A quick question, why does the app report that it uses 41% of the CPU? If it not too much trouble, may you look into perhaps lowering the number? perhaps closer to the magic number of 27% ?

Thanks again.

All 8 5970 GPU's and 2 4850 GPU's crunching flat out here. :-)


That's a crazy amount of flops right there.

Well, it is slowly picking up ATI and CPU work units, and it will be nice when it grabs a few for the green goblin. Thank you for promptly fixing the problem.

I would suggest you stick with the optimized app until they sort out the problems with the scheduler.

I think the project scheduler thinks the ATI app for NVIDIA. Explains why I can get work (I have a gtx) and others can't. It is also corroborated by the fact that boinc requires an NVIDIA card to do the crunching (on the ATI app).

I detached and reattached my machine, but still no automatc WU download.
It seems the server sees only the Nvidia cards.


Did you check your profile to make sure the project is allowed to send ATI work?

I was hoping to get cuda work, so far it hasn't. May someone take a look at the project scheduler to see if it is confused?

Finally got a work unit (had to detach and attach). Seems the system is a bit confused?



My 4850 seems to have been eaten by the green goblin. Also, 1.99 CPUs? Really?

Windows 7 64bit, boinc 6.10.18.

Anyone dare to venture a guess on the throughput of this project? Do there exist server side scripts that can give an (approximate) amount?

Windows Taskmanager:

(percentage reported) * (number of cpu's reported) = actual percentage.

So each task is actually maxing out whatever processor it was running on when it was sampled. If something is reporting >50% then that means that either Windows's scheduler is over counting or the process is multithreaded and using all available processing power.

As for pausing a project. The boinc client scheduler has builtin checking that will more or less give you the exact same result without the need of babysitting the work units. If it believes that it cannot make deadlines, it will reorganize the tasks so that those with earlier deadlines will run first. After all is handled the scheduler will try to bring the projects back in balance with the set resource share.
18) Message boards : Number crunching : Credit lowering (Message 30648)
Posted 13 Sep 2009 by Minicluster
Post:
Credit history comparisons can really only be compared between similar types of work units. Multiple trendlines can be created (cropped between credit/application/workunit changes) which shows progress clearer than examining or comparing histories of two users or projects.

Are cobblestones flawed? Maybe, but anything else that is substituted in will be just as flawed when you compare projects. FLOP comparison will never work.

There does not exist a universal currency between projects. Perhaps we should setup a credit exchange program?

9.9 is working great so far. Vista64 4850 && 3850. Hopefully it fixes the slight VPU-reset issues I have been having with 8.12.
