What version of BOINC are you using? I've read that versions have a limit on how many logical cores they are able to use.

I think it was either 32 or 64 for the 7.14.2 version I use.

Task creation not meeting the very high demand again?

"Total queued jobs: 17,707" That was updated several hours ago and has gone down since Friday.

Check further down the server status page. The lower part appears to say that only 5 tasks are now available. I expect them to be gone quickly.

Message 92627 - Posted: 30 Mar 2020, 14:31:29 UTC - in response to Message 92615.  

I installed as a service, so it needs a reboot after install...



Can you create a cc_config.xml file, save it in the BOINC Data Directory (Usually C:/ProgramData/BOINC, you can check the event log for the correct path) with this, changing "N" to the numbers of Threads you want to run:


<cc_config>
<options>
<ncpus>N</ncpus>
</options>
</cc_config>


I remember someone at the WCG forums with a 32C/64T AMD CPU that was running only 32 tasks.

Once you save the file, go to BOINC-Options-Read Config Files or something like that.


Doesnt make any difference I have other servers that are running fine on 80 cores with load on all 80.... So it's not that BOINC does not support it. I really don't know why it's happening here.

Weird. It should have worked even if all you had was a 1-Core CPU...

Yeah, workunits aren't being generated, I think.
The queue was well over 1 million just yesterday.

There are still 1.5 million tasks showing as waiting to return, so it's mainly a matter of our task buffers running down, but new users will be met with no tasks to download at all which can be discouraging.

There are ways to extend the life of existing tasks, but better to wait and see if supply comes back on stream for a while first. Turnaround time remains important.

More work will be coming soon. It looks like the queue of work is empty at the moment. I'm sure it won't be empty for long.

Looks like I found my answer as to why one more machine I managed to add only got a single task. :)

Work is flowing again.


Turns out they are just resends due to computation errors and 1 deadline miss, but the last queue update does show 13k tasks.

Or it's a ton of verification - not necessarily computation errors.

The wingman workunits ended with computation errors.

I like it when we can keep up with the workload. I enjoy trying to empty the Milkyway cache with my 5 GPUs. It's a pity I can't run Rosetta on them. 17 Teraflops would be good for Rosetta.

I have 2 tasks with Computation error resolution:

https://boinc.bakerlab.org/rosetta/result.php?resultid=1136321350
https://boinc.bakerlab.org/rosetta/result.php?resultid=1136320461

Both looks receiving out of memory at a point.
I have 64GB RAM; it's about Rosetta@home on 32bit or something?

Thanks,
Iulian
