Hi, In a dual GPU system (Win10), WU are worked only on the first GPU but the Boinc Manager shows this on the second GPU. In fact, the second GPU has zero load at this moment and the first GPU takes all the load into itself. As a result, the second GPU always rests, and the first GPU works for two. One WU loads the GPU 2080ti only 20%. This is very small and not effective. |

Thanks for the feedback. As of this moment, the app doesn't support using multiple GPUs (well, the brand new linux client I just uploaded two minutes ago should, but the windows client doesn't yet). As for only 20% usage, as I warned, these current WUs won't stress GPUs too much, but still provide a "net win" over CPU only. WUs coming down the pike will be more demanding on GPUs. Sit tight, we're still working out GPU support, and thanks for testing! |

The newest windows app in mldstest (9.75) should support support running separate WUs on multiple GPUs, please give it a try and let me know if it works, as we don't have multi-GPU machines to test with. |

Hi, Now WUs work correctly: each of the two GPUs has its own load. In addition, I alternately and together suspended and resumed the work of the GPU. The load was distributed correctly in all experiments. Thank you for the surprisingly quick fix! PS. Test computer: Win10 and two identical 2080ti video cards. |
