Help Conquer Cancer finished in 6 months with the OpenCL GPU application vs several more years with CPUs only. The OPN project appears to be huge and we are on track to finish the *first* of multiple targets by October 2021. If we want to finish this project in a reasonable time frame, GPUs are what we need. Here's a quote from the AutoDock GPU GitHub page: "Observed speedups of up to 4x (quad-core CPU) and 56x (GPU) over the original serial AutoDock 4.2 (Solis-Wets) on CPU. The Cuda version is currently even faster than the OpenCL version." What the end result will be, we shall see. But definitely orders of magnitude faster than CPUs alone. BETA testing will weed out at least a significant portion of bad drivers, old GPUs, other issues, etc. I know very well that the GPU is much faster to perform certain tasks, that's not what I'm discussing ..... the CPU and especially the new generations remain far more flexible, and easier to use for a user who has little technical knowledge .... This is a fact that can be verified very easily on other projects like Folding@home... Moreover, in F@H's project summary there is almost an equality between the number of GPU and CPU projects which are often complementary... To conclude, I would say that the GPU is not always the best tool for distributed computing ...  Ryzen 5 3600 Ryzen 7 7800 x3d |

If so many people ask for GPU support, would it be possible to have some references and recommendation available regarding the related hardware?
----------------------------------------For example: - What properties should have a GPU for an efficient (performance vs electricity consumption) support of Vina based science? - What are the recommended do's ... and typical dont's (pitfalls)? - What are the typical GPU configuration for modest cruncher, mid-size cruncher, and high performance cruncher? Since I am not a gamer, I do not have much experience with GPU technical specifications and properties. I tend to prefer AMD GPU (and OpenCL) because the firm is relatively open to the open source community. I think such information would be useful for many members. Cheers, Yves |

The F@H crunchers maintain these two lists of GPU performance. I use Nvidia and right now the best bang for the buck is a used 2080 Ti on eBay ($600 to $700). For a long time the 1080 Ti was the best deal until they announced Ampere RTX 30xx and the gamers flooded the market. I think the Points Per Day (PPD)/Watt is the most important factor. I see they've now added some data for the RTX 30XX that I need to look at.

Hi Aurum,
----------------------------------------thank you for the references. I have an additional question. In the past, the most MB have a graphic chip on board. Currently it is less the case. What would it be better: A/ A "small" graphic card for visualisation (screen/desktop) and a powerful graphic card for crunching purpose ? B/ Only one "powerful" graphic card for both: visualisation and crunching? Cheers, Yves |

I don't have any CPUs with graphics onboard. I figured it wasted real estate so I avoided them.
----------------------------------------If I'm streaming a movie then I turn off BOINC GPU on my desktop PC. For office & web browsing I can't think of a BOINC GPU project that interferes in an annoying way, maybe a pregnant pause here and there. You can definitely dedicate the lesser GPU to your monitor and dedicate additional GPUs to BOINC using commands in your cc_config and app_config. I haven't tried that since my desktop PC only has one GPU and most of my calc cluster has a single GPU. Linux has issues dealing with 2 GPUs on headless computers. If I could find a reliable solution I'd double up more rigs. ...KRI please cancel all shadow-banning |

Thank you Aurum.
----------------------------------------I am currently planning the replacement of one of my old Phenom II x6 (1055). The machine (probably a Ryzen 9 3900XT) will run Linux (probably LinuxMint), and will have a screen. Based on your remark, I will avoid to have 2 GPU in this new machine. Is it correct? Cheers, Yves |

I tend to prefer AMD GPU (and OpenCL) because the firm is relatively open to the open source community. No one knows yet what will work best; it varies by project. But since this is an OpenCl app, the AMD cards should do well. I have a bunch of Nvidias, and will be trying out a GTX 1060 first, but I expect my RX 570 will do better. |
