Hi,
When syncing Rosetta, the project automatically downloads a huge amount of WU's at once :
- I now have 226 WU's in wait(3 hours each, used to be 6 hours each)
- I'm currently processing 10 WU's on my system.
- The validity period is only 10 or 11 days.

I'm also participating in LHC, Atlas, Climateprediction
which means that I am forced to process all Rosetta's continuously to be able to meet the deadlines and not
losing out on any jobs, effectively halting all other projects.

I have fiddled around with setting "Maintain enough work for an additional (Enforced by version 5.10+)" to 1 day, but Rosetta just seems to ignores this and keeps downloading this many jobs.

Is there any way I can prevent this from happening ?
I'm ok to download quite a few jobs and prefer to have a buffer of say 3 to 4 days to ensure sufficient work even if a server goes down for a couple of days.

But this many jobs is simply choking my system & hindering other projects.

Many thanks for investigating into this !

Kind Regards,

K.

Hi

The work-fetch is managed by BOINC, rather than Rosetta. If you've changed some settings then that might be why. I wouldn't worry about it though - BOINC will abort the tasks if they're expired, and if they are processed but miss the deadline then they'll still be credited and still be useful.

If you give the BOINC Manager a day or so, without trying to fix it, it should be able to adjust to request the proper amount of work for your operating environment. As you start any project, the BOINC Manager has to take an initial guess and how to make things work, and it automatically adjusts things from there.

If you have recently increased your preferred WU runtime setting on the R@h website, I'd suggest setting it back and only increasing it gradually over the course of a few days.

Hi D & Mod.Sense,

Thanks for the quick response !
I'll wait it out and see how it behaves.
