Well..

I think all apps were improved, and the credits lowered in basis to that improvements...

But what about windows CUDA 32bits...? what happened...?

mine are running fine: P4D/9600GT

but G200 cards are suffering due to the older CUDA-version currently used..

Yeah..

My Q6600/GTX260 is running fine, but there are not or only a little improvement...

What is yours in your 9600GT? (see elapsed time in the log of your task, not cpu time in your project's web task list)

you got the link;)

wht you do not see - it's a high-clocked G94 chip with only 64 shaders - and average runtime looks to be under 12 minutes right now.

you need to look into the results to see the actual runtimes..

anyone got a fast GTS250 online?

Yes, but I'm refering to what is the improvement for you between the old and new app...:)

can't tell - that host was running W7x64 during the first batch, and i even got no clue if the WU's are same as back then.

the only thing i know, is one left over pending WU talking about "Wall clock time: 1279.046247 seconds"

If I'm not wrong, credits are divided by more than ~5 but win 32 CUDA app is less than a ~15% of speed up. Of course, I can be wrong...

Sorry I think the speed up is near to 0%. I remembered now that I OCed my card a 12% more before Collatz restarted... So... where are CUDA improvements...? :)

Only in CPU and/or ATI...? (I'm only asking...:))


Best regards.

Speedup on 32bit Windows with GTX260 around 57% :)

old: 14min
new: 8min

The same card GTX260(216) running Collatz as only project in the computer (no cpu`nor gpu projects):

Old stock speed: 9:11 min.
Old oced at 11%: 7:40

New oced at 23%: 6:27

I think is not a 57%...

But sure Slicker can tell us something more accurate about all that...;)

The situation before the shutdown was that we had quite okay GPU applications, but a slow CPU one.
Now both are approximately on the same level and further improvements just around the corner. In another thread I posted already some results with an improved version giving a massive speedup. The same tricks can be easily used on nvidia GPUs (and CPUs) too.

Slicker has worked hard to get this project up again. Give him some days to port the new stuff to CUDA, thoroughly test the apps and you will have your faster CUDA version. But a fast quad running a 64Bit app will rock too ;)

I know... was a hard work from all of you... Slicker, Crunch3r and you...

I only surprised by the poor improvement of CUDA version between the other apps and no news about this.;)

And if you need me for standalone testing (read you, Slicker or Crunch3r), you can call me as you know...;)

The emphasis was on the securing the results against some malicious modifications and the speed of the CPU app (which was quite poor) this time. The ATI app also didn't gain much (or even nothing, I don't know exactly).

But the next round will be more even handed to the different architectures, I guess ;)
