Is it true that Potamos tasks take 150d to complete? Seems unrealistic to me. Computer is running Arch Linux [6.6.72-1-lts|libc 2.40] and, cpu is Genuine Intel(R) CPU @ 2.00GHz [Family 6 Model 62 Stepping 2] BOINC version 8.0.2 |

There aren't enough hosts and completed tasks, so BOINC makes incorrect estimates. You might see a task that is projected to take 20 minutes actually take 2 hours.

In reply to vaughan's message of 2 Oct 2026: Is it true that Potamos tasks take 150d to complete? Seems unrealistic to me. Longest task I have seen is under 3 days on a Ryzen9. 150 days for a BOINC task to finish hasn't been seen anywhere as far as I can tell since the days of old Met Office code tasks for CPDN. |

Will get messy if one wants CPU-only WUs on one project and GPU-only on another. The only CPU WUs I've gotten so far are Kampylos and they run in 30ish minutes.

No project has that a option. It is a design choice the builders off Boinc have made a long time ago |

In reply to Aurum's message of 2 Oct 2026: Will get messy if one wants CPU-only WUs on one project and GPU-only on another. it's quite easy to setup and using device profiles i can create CPU-only, GPU-only, mixed profile on each project and allocate that to devices for example here while M1 GPU apps are failing, i created a CPU-only profile for that computer I crunch for Ukraine

BTW, I meant application and not project. I doubt default, home, work, or school profiles can solve this. E.g., if I want to run Kampylos CPU WUs I have to check Accept CPU-only Work. And if I also want to run Potamos GPU WUs I'll also get Potamos CPU WUs that run forever and therein lies the problem. And you cannot control CPU and GPU WUs from the same application individually in your app_config.
