Instead of running this task, BOINC keeps downloading new Rosetta tasks and running those.

You probably have an app_config.xml file, with a project_max_concurrent entry. Get rid of it. BOINC has a bug.

Nah, that's where it keeps downloading more work over & over again ignoring deadlines & cache settings.
I suspect this one will be a Task that in the BOINC Manager will show as running, but if you look in Task Manager it will show 0 CPU usage. Some fail to start, while others start but never actually finish.

That is the app_config bug. The 0 CPU usage bug is not actually 0, just very low. It will actually occupy a slot and you won't get one to replace it until you abort it.

But I have seen Rosetta download too many pythons even without either problem. So it is not all that reliable in the best of times. I just yesterday had to set NNW after three days nine hours of download, though I had set the buffer to 1 +1.5 days, and did not see any 0 resource ones, and I don't have an app_config any longer either.

It may just be that the estimates are off, though they look OK at eight hours, which is actually a bit long. They usually run six hours or less on my machine. But who knows what value it is actually using. It may not be the one displayed.

Could it be that the Python tasks are only for teaching their younger students how to create tasks?

The only thing that I recall is that one of their experimenters was using them, and I don't know for what purpose.
It was not exactly a ringing endorsement that they would be widely used as a basis for new work, as we might hope.

If anyone can find a mention of a use, maybe they could post it.

I belive this is what you are referring to.

Thanks. That looks much more promising.
I have ordered more memory, and will put another large machine on it if it is stable. But 128 GB may cause problems. You have to be careful.

PS: I know I will still have at least the "Vm job unmanageable" problem, which prevents the further download of any work unit until it times out or you reboot. So I am going to try an automatic reboot.
https://askubuntu.com/questions/13730/how-can-i-schedule-a-nightly-reboot

But the first method shown did not work.
Using sudo gedit /etc/crontab
00 6 * * * root reboot
looks more promising.

And I am hoping that they will solve the 0 CPU jobs, whenever that will be.

Even though I have the BOINC client set to use up to 6 cores the Rosetta python project 1.03 tasks only ever single thread which reduces the amount of work the system can do.

Is this a config issue?

No, they are single-threaded. Each work unit occupies one virtual core.

---

But I have 6 virtual cores available so why are there not 6 tasks running at the same time?

I don't have this issue with other Projects so it is not a system issue

Even though I have the BOINC client set to use up to 6 cores the Rosetta python project 1.03 tasks only ever single thread which reduces the amount of work the system can do.

Is this a config issue?

No, it is due to the very large amount of memory each Python task reserves, 7.45 GB. They seldom actually use more than 100 MB, but that's not as important.

Computers with only 16 GB of memory cannot fit in two of those tasks and also the other programs needed to keep BOINC running.

Each of the python work units (the only ones available at the moment) take 8 GB of memory. They don't actually use that much, but they require it for download.
Your machines have 16 GB each, so they could run only two at most. Do you have BOINC set to use 100% of the memory?
(As robertmiles said, the OS takes some too. I am not sure whether BOINC takes that into account.)

---

OK, so that is the issue, I understand.

Thanks a million for the feedback.

Time to add more memory!

So.. I started to crunch R@h after long break.
What should be running time for python 1.03 (Vbox64) units?
Atm. I have 3 of those running on AMD 5900X and those are now @99.996% after 57hours.
2 more units are "Postponed:VM environment needed to be cleaned up."

Congratulations. You have managed to hit both of the problems right off the bat.

You could have aborted the 99.996% ones in the first five minutes, when they would show less than 1% CPU usage (I use BoincTasks to check that).
And to fix the postponed ones, just reboot. Otherwise, you have to wait about a day for them to restart.

You have made much more progress than most.

Lets see now
Python ram calculator says 12 cpu`s times 8 gig each [allowing a bit] seems you need to fit about 100GB to be safe to run full on
And that`s no joke
well the way RPP tasks hog ram its a sad joke the project needs to do some thing about
and this is only the hundredth {or so} post to `hint` at it
OK folks I`le go back to banging my head on the wall . . . .

I just encountered an issue. My BOINC client cannot recieve any Rosetta@Home projects.
The log says:

22/11/2021 20:40:55 | Rosetta@home | Sending scheduler request: To fetch work.
22/11/2021 20:40:55 | Rosetta@home | Requesting new tasks for CPU

After that I installed VBox but it still outputs this error.
I also tried to reset the project but it doesn't make any difference.

What can I do now?

What version of Vbox? A version recent enough to include vbox64 is required for the Python tasks.

How much memory does your computer have? 12 GB is about the least that will run Python tasks, and then only if you have enabled virtualization in the BIOS settings,

Under Options, then computer preferences, you may have to tell BOINC that it is allowed to use higher fractions of the memory and the disk space.

There's an occasional task with much smaller requirements, but people try to download them much more often than they become available.

Also, you may have to restart or reboot your operating system (probably Windows or Linux) before such changes will take effect.

Did you restart Windows? If not, did you restart BOINC?
It will likely be fixed if you restart Windows.

Never has so much been asked to do so little for so few.

VirtualBox, is not compatible and does not work in Windows if Microsoft Hyper-V is enabled.
First of all, uninstall any component of Hypr-V from your system.



Windows it will restart, then try again.
If again, BOIN Manager, should give you the same warning, you will have to open 'Windows PowerShell' (with administrator rights) and type (copy-paste):

bcdedit /set hypervisorlaunchtype off and press [OK]
Subsequently 'exit' ...

Restart Windows and now BOINC, should be able to download the wus

I am starting to get some server aborts (202) on the regular Rosettas, so they must have some bad ones.
Also I see some pythons eliminated that way too, which is good. Hopefully they are finding and getting rid of the "0 CPU" tasks.

I still get "Vm job unmanageable" suspensions on the pythons, but that may be beyond their power to easily correct for a while.
My automatic reboot cron job (as posted previously) takes care of it by rebooting daily.
