I had some come down. Killing my PCs. I'm running an Nvidia 2080ti. The GPU-Z program indicates that a single workload uses an average of 7% of my GPU and the GPU is frequently IDLE. When I run two workloads simultaneously, the GPU load goes to 23% average. The early workloads took 40-60 seconds instead of 1 hour like the CPU and generated 5 to 10 times the credits. WorldCommunityGrid uses COMPUTE time to rank users. I imagine that the project will make some adjustments/improvements over time. Since the GPU version requires 100% of a CPU (for me), they can use VTUNE to optimze that half of the program. |

I had some come down. Killing my PCs. My gpu is at nearly idle until it gets a couple minutes into the task then it takes off. I use msiafterburner to monitor it. |

I had some come down. Killing my PCs. The laptop has a Radeon RX460, the desktop an Nvidia GTX750. 2 GPU tasks run at a time on the 4-core laptop, just 1 on the 16-core desktop (don't know why). Both die a horrible death. |

I had some come down. Killing my PCs. I would think maybe memory as the 750 only has 1 maybe 2gb of ram while the 460 can have 4gb of ram on it |

I had some come down. Killing my PCs. You're right - that explains it Laptop: Coprocessors [2] AMD AMD Radeon R7 Graphics (4096MB) OpenCL: 2.0 Desktop: Coprocessors NVIDIA NVIDIA GeForce GTX 750 (2048MB) driver: 465.89 OpenCL: 3.0 |

I had some come down. Killing my PCs. WOO HOO!!! I have a stack of 70Ti gpu's in storage right now that only have 1gb of ram and 1 750Ti that has 2 gb of ram also in storage. I was going to setup a mining rig and even had it built and ready to run but the 3??? series gpu hit the market and there was no chance I could do anything constructive with it. I thought about crunching with them, and I still may, but not right now. |

Another interesting project: OpenMM+Pytorch+Gpu |

Nice news ... glad to be able to assit in fighting Corona ... WCG has a working GPU app for Covid workunits... I'm running both WCG and Rosetta on my 3 crunchers |

How do you do this at the same time? Crunch Boinc and Folding@home I mean? |

From Foldit: Another reason is that the AlphaFold algorithm runs much less efficiently on common CPUs than on GPUs, which many players may not have. If you ran AlphaFold on your CPU at home, it might take an hour to get a result back. However, if we use our GPUs at IPD, the actual processing will go much faster. Since most of our recent Science puzzles have had fewer than 100 active players at a time, we think that players can get results faster if we process AlphaFold jobs on our server GPUs. So, seems that some simulations may be done on our gpus (if they want). |

Accellerating RosetTAFold NVIDIA just released an open-source optimized implementation that uses 9x less memory and is up to 21x faster than the baseline official implementation. |

I took the liberty of citing it on GPUGrid. I think they are more likely to send us stuff. PS - Why don't you do SiDock? They might be interested for their new GPU app, or thereafter. You could answer their questions better than I could. |
