Multiple clients completing the same WU

Post by bikeaddict »

Here are some WUs that four clients completed in the same day. The project has a timeout of two days. This looks like something malfunctioning and reassigning the WU way before it times out. It's a waste of computing resources to do the same work multiple times.

https://apps.foldingathome.org/wu?p=182 ... =3&gen=195

It would be easy to see how many more there are in your database with a query of WUs with code=Ok, date(assigned) = date(returned) that groups by PRCG and having count(*) > 1

That is probably dynamic timeout feature at play.
If I tried again to argue of its removal as a default with the main fah dev, I would probably get banned :D

What is the dynamic timeout, and how does it work?

Surely setting a floor that the dynamic timeout cannot go below would help.

Dynamic timeout is a "wonderful" feature which adjust timeout automatically depending average return rate for the project, or something like that. It was enabled during COVID where it really worked. But not anymore
I asked researcher to check if that is the cause and to disable it
