ecm task resets on computer reboot

[nbfields]

Hello to all! I am running a task for yoyo@home via the software program BOINC. My computer is Fedora Linux 39, and the task is for ecm P2 705.01.

The task seems to proceed as normal in the expected manner, but every time I turn my computer off, the task's progress resets. For instance, when I turned my computer off on Friday the task read ~ 11% completion. Looking now having turned my computer on ~ 10 minutes ago, the task reads .350% completion. As the task is quite long (the remaining estimated time measures 10 days at the start, but in reality it appears to be only ~ 40 hours on my machine based on the progress bar), this poses quite a problem to being able to finish the task!

This problem does not appear to be the case for any other project I am involved with through BOINC. My tasks are set to checkpoint every 60 seconds, so the progress should have been saved (and indeed it is for other projects). I would quite like to submit work to this project, so if anyone else has seen this problem and/or has suggestions on fixing it, that would be great. Thank you!

This phenomenom is due to the fact that ecm doesn't checkpoint.
These tasks are rather suited for machines that run 24/7.
You can try if they overcome hibernation (instead of shutting the machine down) if you set the BOINC (not project) preferences to leave tasks in memory when preempted.
There are a few projects out there that have apps without the capability to checkpoint, but most will, so if your machine shuts down daily you should avoid the projects or applications which don't checkpoint.

The 60 seconds setting allows the client (and running applications) to write to disk every 60 seconds, but if there's no need, it won't happen.
