Hello !

Nice ! A new GPU app.

Would you please be so kind to confirm the app name to be
used in order to write a short app_config.xml, as the
0.01 CPU allocation is not enough at all.

Thank You !

Kind Regards,

Philippe

I think that 0.01 (1%) should be ok. On my PC's CPU usage is about 0.003 (0.3%). Try 0.05 first and let us know.

Thanks

Hello !

Thank You

I will reload some for my GTX770 + GTX570M=> 2 more for your stats ;)

Thank You

I'm interesting in GTX770.

Thanks

This is wonderful!

Thanks Radim & HA-SOFT!

I see very low CPU usage & high GPU load. Perfect!

Wanted to send you this message via PM ...

Hello,

I have another question : how can I force receiving AVX CPU UT's ?

Thank You

Philippe

NB Will leave the GTX 770 on the project tonight, if this helps ;)

Only way is to use app_info, I think. On Intel Haswell cpus (4xxx) the speedup of AVX is about 40% comparing to SSE3.

@Phil1966:

I'd posted a sample app_info.xml over there.

Now you have to add gpu part if you want to crunch on gpu also.

It's more than 2 hours that I try to get some WU for GPU only (CPUs are fulload on Rosetta Challenge) but still "got 0 new tasks".
Tried to reset and detach/attach the project also.

There's some trick to get wus?

TIA

Look at your boinc log.

Maybe you have the same problem as I had:

Uhm... I'm on Win7/64 and at the attach time the only eligible message in the log seem to be this:
"29/12/2013 21:30:08 | Asteroids@home | Tasks for CPU are available, but your preferences are set to not accept them"

So maybe apps && WU are for Linux only at the time? In fact after disabling CPU fetch the data folder is empty.
About the trick, maybe I'll try it after the chellange end.

Thank you very much, anyway.

Riccardo

Congratulations guys!
-- im so happy for this and look fwd to TURBO performance boost in next weeks :)


-- PS.: i have AMD graphics only :-/

Yes, very low CPU usage, that's nice :) Well done!

If one has enough memory on the card one should be able to run 2 or more tasks simultaneously?

I have 2 tasks completed and verified and I see the credits awarded are the same as for CPU tasks. That suggests the GPU tasks and CPU tasks are the same size, is that correct?

GPU and CPU crunch the same tasks. Same size and same credit.

Parallel tasks bring no profit, I think. Occupancy of card is 100% for CC3.X and 70% for CC2.X.

I do not expect performace boost from GPU comparing to CPU app. The most efficient configuration is Intel Haswell with AVX app. Only GTX Titan is faster (for one task) but needs more power.

Could we get an OpenCL-App for AMD GPUs too ?

What about AVX-App on current AMD CPUs ?

Has to be asked... Mac?
I have a 680MX that would be nice to run. Happy to be an app_info'd test case if you need one, and willing to try compilation if needed (tho i guess i'd need the nvidia cuda sdk, which i don't have).

My windows machines thank you and add a... 430... and a 760 to the mix. will report the pain and glorious (or otherwise - these would be DP float calculations right?) times of those when I've had a few tasks.

Cheers, Andrew
