Got two nVidia K80 (but only one installed yet) about a week ago and have realized that if I shut down the network, I will run out of GPU WUs within 2-3 hours. Have tried to change the values, both in the account settings and in BOINC Manager, but ... It seems that the requested amount is related to the CPU, but not the GPU's. Is this problem related to MW@H or BOINC Manager.? Anyhow, it's sort of a 'nice' problem ...

Number of tasks requested depends on the BOINC settings for "days of work" and "additional days of work" with the maximum being 10/10. But the project limits the total amount of tasks carried by a host to ngpus X 300. So for your two cards you will be allotted 600 tasks maximum to be carried daily in your cache. |

The K80(s) will then be waiting a lot, as I normally keep the network shut down at times when I'm not at home or asleep. Sad ... Edit: The K80 is a double GPU card, so it would be 900. The K80 will finish the majority of those in 'no time', as each GPU on the K80 finish every WU (de_modfit_8x_bundle4_4s_south4s_gapfix) in less then one minute.

Well then, your next choice would be to spoof the gpu count to increase the number of tasks allotted. Edit the coproc_info.xml file to clone the original card entry multiple times then lock the file afterwards so BOINC can not update or change your new values. |

Nice one! A 'quick-and-dirty', like that and are going to try it. Thank you! [ i9-14900K/128GB/A2000 + i7-11700K/128GB/A4000 + i5-10400T/32GB/UHD630 + i7-7700/32GB/A5000 + i7-3770K/32GB/P4 | Ubuntu 22.04.4 LTS ] |

Have tested it. It only produce a number of GPU calculation errors. [ i9-14900K/128GB/A2000 + i7-11700K/128GB/A4000 + i5-10400T/32GB/UHD630 + i7-7700/32GB/A5000 + i7-3770K/32GB/P4 | Ubuntu 22.04.4 LTS ] |

I always run several BOINC clients when running MW to allow for 300 tasks on each client. Radeon VII spits them out in a couple of hours. Stagger the clients a bit and the card will always stay busy. |
