It works also on Quadro series ? I have this one: NVIDIA GPU 0: Quadro FX 1800 (driver version 331.82, CUDA version 6.0, compute capability 1.1, 768MB, 8381137MB available, 264 GFLOPS peak) but cannot get work: 30/12/2013 10:57:55 | Asteroids@home | Requesting new tasks for NVIDIA 30/12/2013 10:58:00 | Asteroids@home | Scheduler request completed: got 0 new tasks |

This seems to be the case because they get the same credit (480). . |

Yes. AVX on 3xxx stuck on memory loading (CPU does two SSE3 op). AVX is for 4xxx CPUs. If the WU's for the GPU and the CPU are the same, just different apps, then a GTX770 is twice as fast as a single i7 CPU thread, but only has 1/4 the performance of the entire CPU. Yes. It is. |

Then I don't understand why you launched this GPU app ? Is it a test for a futur "different / new type of" WU's ? Have tryed AVX WU's on an i7-4770K ... but I don't know why, very very slow + only increasing the CPU temp. I guess one should run AVX on 4 cores only => no real gain <-> SSE3 on 8 cores ... Wish you a Happy New Year ! |

Last modified: 30 Dec 2013, 13:21:54 UTC Then I don't understand why you launched this GPU app ? To give an option for crunchers to select "right" app and of course to explore usage of GPUs for next development. Is it a test for a futur "different / new type of" WU's ? Not for now, but we will see in future. Have tryed AVX WU's on an i7-4770K ... but I don't know why, very very slow + HT cores share FPU units so no profit from HT. For example: cpus without HT like i5-4670 can make the same work with AVX as 4770 (SSE3,AVX) and has better power/price ratio. |

Could we get an OpenCL-App for AMD GPUs too ? Open-Cl is on our todo list. One of our volunteers decided to develop opencl app as shool project so we are waiting for him. What about AVX-App on current AMD CPUs ? You can try it with app_info, but AMD is very poor on AVX. AMD CPUs simulate AVX with SSE3. |

My poor little GT610, which is probably one of the slowest GPUs on this project, doesn't think that the new app is very fast. 610 is very slow, I have three 610 with passive cooling at work. |

Ack! 11,000-12,000 sec on my FX-8150 host with a 550Ti... :-( Can that be optimized? Thanks for the feedback. :-) Oh, well...I guess I'll keep that GPU running Einstein. |

Great news for the project, but to be honest I am somewhat disappointed by the performance of mid-range card. I guess I will be sticking around with my CPU somewhat longer... These are expected results. GPUs are very specialized and it's hard to fit code to every hw architecture. |
