Message 1830 - Posted: 28 Aug 2008 | 9:12:22 UTC

I have uploaded new work GPUTEST3 and new applications for Linux and Windows. Among other little things these are fixing a mistake I made in flops counting (sorry) which affects credits. So we were undercrediting because our estimate of the Gflops of the application was not accurate. Writing the publication presenting the application, we have noticed it.

You mean 6.43? Soon my Comp will start crunch them. What changes in application?

Uhmm,
it should work on your system.
Have you tried with normal non-beta drivers like 177.8x?

Your shader frequency is slightly overclocked, it should be 1512000. Could you turn it down using Nvidia utilities.
Let us know.

Message 1961 - Posted: 30 Aug 2008 | 18:45:50 UTC

I'm now getting 6.43 on my hosts, all seem to be running well. One host had a problem with the first one but since has been ok. The others seem to be doing ok, but I've only got 1 or 2 completed with each, still with 177.84 driver. I do not have enough completed results yet, but it appears that 6.43, at least for my 3 hosts, is about 2,000s faster than 6.41. I need to let it run some more for a few days, but then I think I can try to see if 177.92 driver works. I've got a lot going on this Holiday weekend anyway.

The 6.43 is here running on 3 PCs, 2 are working with a 8800GT, one with a GTX280. All are running fine. I use on all 3 PCs driver 177.84.

The 6.43 is not faster - the formel for the credits in 6.41 was wrong. Therefor the difference.
I think the 177.92 is faster than the 177.84. The nvidia guys said it in the beta forum.

6.43 running fine and no difference in run times. I updated to 177.92 beta today and projected run time (after 2 hours) was about the same.

I'm happy to announce my first finished WU on the project and this batch. :)
Was about time to get rid of that Zeros...

I crunched it with a Gigabyte nVidia 9600 GT card on Windows 32-Bit.

Edit:
Sorry for double-post. Messed up with the buttons...

Is 6.43 aplication 32 or 64 bit? or are 2 diferent versions?

BOINC manager is in 32 and in 64. So when it run on x64 Systems aplication 6.43 it runs it in 32 or in 64 bits mode?

The Linux application is 64bit, the Windows version is 32bit.

I assume that it doesn't make any difference, if it is 64 or 32 bit, as the workload is processed by the GPU anyway. So the app does not profit from 64bit architectures improvements like more registers and stuff like that.
Please correct me if I'm wrong :)

I believe that is correct. Plus unless a CPU application is specifically optimized for 64-bit, there really is no advantage to 64-bit.

I find interesting error:

http://www.ps3grid.net/result.php?resultid=49857

How it happends?

I have delayed on one hour computing using Boinc Manager.

I uninstall 177.84

Restart

I install 177.92

Restart

And Boinc Manager to my suprise cancel 4 WU and download new. One of those cancel WU was after 13000/50000seconds of crunching....

Now It starts as usual new WU

I am very Curious if new drivers will be faster on WinXPS2 32bit than previous 177.84.

Be sure to let us know if you find 177.92 is faster or the same speed as 177.84.

Btw, I am still using 177.45 drivers and they seem to work fine.

I'm not sure what you mean by "delayed on one hour". But I have a suggestion what went wrong for you:

When I played around with different drivers I switched BOINC to "no network activity" and made a full backup of the BOINC directory. When I uninstalled a driver (because I wanted to downgrade) and windows rebootet, it didn't have a driver ready. BOINC was installed as a service and apparently started GPU-Grid and errored out because it didn't find a CUDA device. After the driver install I rebootet and restored the backup.

No it isn't.

Yes! Yes! Yes! Fuc..... 177.92 - my system was so slow that I am already back to 177.84. GUI was nightmare....

You have rigt with diagnosis - after reinstaling Boinc don't found CUDA and reset all WU, so i am in 24h wacation from crunching... PS3Grid :(
