WUs are not all the same due to the nature of the search algorithm. While task generator tries to split the work into equal chunks, it's impossible to predict how much time exactly each WU will take.

It was just strange as it gradually got longer to finish.

I got several wu that are taking a very long time to get done, the latest one is: over 23 minutes and only at 85% done. I noticed other running longer than usual also.

Hello everyone,

I see there are no recent messages here, but I think I've got an issue about this topic.

I have some WUs taking much longer than the estimated time, leading to a non-respect of the deadlines (that are particularly short in comparison of other BOINC projects), even when I leave BOINC running 24/24 7/7.

Last example today with an application named "Amicable numbers up to 10^21 3.00 (mt)" : estimated time : ~ 1hr16min but took 2hr39min to finish (ie. twice the estimated time!)
Those WUs require 8 CPUs to run, so I've set 100% of my 8-thread CPU in BOINC manager options.

When I watch the evolution of the remaining time, it appears to be decreasing for a while, and then increasing at 1second every 2-3 seconds, and then decreasing again etc...

My config: Ubuntu 22.04 / CPU Intel core i7 7700 HQ / RAM 16GB DDR4

Any idea to solve it? Is my laptop too 'light' to run them?

Thanks in advance
