Thanks again for all the help on the stress test. It is truly amazing how much power there is available. Thanks, -Uplinger And the amazing thing is we are still fine tuning. I just calculated with the last test I can hit 2,500 WUs a day on a single card. CPU is now my bottleneck, takes all 16 cores @100% load just to feed the it  Wish my 32 core wasn't still on back order; I would have loved to see what the GPU could handle with it feeding it. :)I hope you all can greatly increase GPU units after the stress test and keep this going. I am highly tempted to go buy an overpriced card. |

From the numbers I have seen, the higher-end cards don't get you much more performance. Maybe someone here with an RTX, for example, could show what they are getting. |

After fine tuning my card, I got 17M points yesterday with my RTX 3080. I might be able to get it to 20M. There's still headroom, because it's not running at 100% all the time.  |

Maybe someone here with an RTX, for example, could show what they are getting. one of my crunching machines has two RTX3070 inside (in fact, almost unbelievable, I bought this machine last week at quite some expence, solely for grid-computing purposes). However, with the current WCG GPU tasks not using much of GPU (which has been addressed here several times in the past two days), the performance of these cards is bound to be poor  So let's hope that future WCG GPU tasks will make full use of the GPUs.

When you say fine tuning do you mean in the app_config like gpu usage 0.1? |

Hardware see on my statistic on the bottom. But two of them, not one!

When you say fine tuning do you mean in the app_config like gpu usage 0.1? Exactly. If I remember correctly I have gpu usage of 0.1 and cpu usage of 0.25. The next step would be to see if gpu usage of 0.08 (12 concurrent units) results in overall more work being done or not. I think yesterday it crunched about 1600 GPU workunits? My GTX 1650 low profile card (limited to 75W power draw) seems to be able to do gpu usage of .25 and cpu usage of .5 pretty good. That maxes it out at 100% CUDA utilization pretty consistently. That resulted in a bit over 3M points yesterday. Tomorrow I'll be focusing on seeing what I can do to optimize my Quadro M2000. Unfortunately, my GT1030 maxes out at gpu usage 1.0, so the Quadro is the next frontier haha. [Edit 1 times, last edit by DrMason at Apr 29, 2021 6:31:00 AM] |

Its my daily use computer so i might only run it at a higher load when i dont use it as the noise can be quite anoying. |

That resulted in a bit over 3M points yesterday. hm, I now made some changes on one of my crunchers, according to the settings described by you above. So when reducing the value in GPU usage (say from 0.5 or from 0.33 to 0.25), the number of concurrently running tasks increases accordingly. However, regardless which change I make in CPU usage (say from 1 to 0.5 or 0.33 or 0.25), still one running GPU task utilizes 1 CPU core to full extent. How come? |
