Hi. How can I set a maximum number of download for this project?

Tn-grid has limit of 8wu per core, and 512wu per pc, even with a Epyc (64c/128t)
With your 3950x you can reach 32x8= 256 running wu

Alessio, Are you asking because you want more WUs or fewer???
If fewer, you can set the Resource to zero and then it should only send more when you run out.

I have a Ryzen 9 3950X and I'm running 30 WUs simultaneously. I'd like to set TN-Grid to download only 20 tasks at a time. So I can run TN-Grid and other projects at the same time.

Alessio, TN-Grid does not give us that kind of control like WCG does. But you can still make it work as you want using app_config.xml files in your project folders. Now I like to run both Rosetta and TN-Grid as my CPU projects.
In my gene.disi.unitn.it_test folder I have:

<app_config> <app> <name>gene_pcim</name> <!-- needs ? GB RAM per WU --> <!-- Xeon E5-2686 v4 18c36t 32 GB 45 MB L3 Cache --> <max_concurrent>25</max_concurrent> </app> </app_config>


In my boinc.bakerlab.org_rosetta folder I have:
<app_config> <app> <name>rosetta</name> <!-- needs 5 MB L3 cache per mip1 WU --> <!-- needs 1.5 GB RAM per WU --> <!-- Xeon E5-2686 v4 18c36t 32 GB 45 MB L3 Cache --> <max_concurrent>9</max_concurrent> </app> <app> <name>minirosetta</name> <!-- needs 5 MB L3 cache per mip1 WU --> <max_concurrent>1</max_concurrent> </app> <project_max_concurrent>9</project_max_concurrent> </app_config>

You'll get more WUs than you need but you'll run what you want.
My totals leave 2 CPU threads for GPUGrid WUs.

Hello,
when do I get this 8 WU per Core?
I am running the project since some days now with more then 200 valid WUs but get only 1 WU per Core.
Its the same on 2 different PCs. The project was added completely new for both PCs.

Best Regards

I think you need to set your work buffer from your boinc manager preferences
with yor 1700 and 3950x setting 1day + 1day, is more than enough to reach 128wu and 256wu respectively

You need also to considerer the max concurrent wu limit.
If you have set, for example; a limit of 10 concurrent wu, trough an app_config.xml file, you will recieve 10*8=80 wu even with a 10+10days work buffer

The buffer is already set to 1 day. Einstein gets much more work.
The project was added new, no config files.

I tried now 10+10 days and on the Ryzen 1700 I got now more WUs: 128 :)

But the 3950X still has only 28 WUs.
Do 24 Dez 2020 21:42:14 CET | TN-Grid Platform | Reporting 1 completed tasks
Do 24 Dez 2020 21:42:14 CET | TN-Grid Platform | Not requesting tasks: don't need (CPU: ; AMD/ATI GPU: )

the cc_config is quiet short:
<cc_config>
<log_flags>
<task>1</task>
<file_xfer>1</file_xfer>
<sched_ops>1</sched_ops>
</log_flags>
</cc_config>

Try to suspend others project, than ask work for TN-grid

If you want, the he following is the cc_config.xml i am using

<cc_config> <options> <allow_multiple_clients>1</allow_multiple_clients> <max_file_xfers>50</max_file_xfers> <max_file_xfers_per_project>30</max_file_xfers_per_project> <report_results_immediately>1</report_results_immediately> <ncpus>12</ncpus> </options> </cc_config>


set the ncpus value to your correct thread number: 32 (3950x), 16 (1700)

Others values are for multiple wu trasfer


By the way i write down also the app_config.xml file to put in the project folder (C:\ProgramData\BOINC\projects\gene.disi.unitn.it_test)
whit this you can specify the maximum number of concurrent wus. It's useful if you want run multiple projects

<app_config> <project_max_concurrent>12</project_max_concurrent> </app_config>

I have no other projects running for the CPU at the moment that I could suspend.
Einstein is using the GPU. If I suspend Einstein, nothing changes.

I dont want to set any fix limit for CPU cores. Such limits might be the reason for the problems like I have - so I avoid this wherever possible.
The 1700 got some more work now with setting of 10+10 days. But switching back to 1+1 it doesn't request new work again.

The 3950X still has only 1 WU per core even with 10+10 days setting.

If there are no other ideas I will ignore the problem, because other projects run fine and TNgrid also, as long as there are always enough WUs available.

To get a fully populated cc_config.xml instead of the minimal default, all you have to do is change ONE Event Log Options parameter in the Manager menu and Save the setting.

That will populate all the possible settings of the cc_config.xml file.

You can then change the one setting you adjusted back to whatever it was before and it will keep the full set of config file parameters.

I added TNgrid new on the fresh installation of Ubuntu and Boinc on another PC.
This PC also has the same problem. Only one WU per Core. Even after more than 20 valid WUs crunched.

For me this means, it has nothing to do with the PCs itself, no bad settings somewhere, its just project related.

You've got a client limitation being applied through the Manager likely.

If I wanted I could have all of my 48 cpu cores crunching TN-Grid and over 500 tasks in the cache.

Look for storage limits, task limits being set on a different venue than you think the hosts are set for.

The only difference I see in the settings is that one PC is in the SCHOOL profile and the other two have no profile.
I have moved one of the PCs now also to SCHOOL, but no change. SCHOOL and standard settings are identical anyway.

Maybe that its also a limit from client side in conjunction with the project - but I have installed Boinc, added the projects and thats it. I have not limited anywhere the number of cores to be used. And even with 10+10days there is not a single WU in the buffer. 4 WUs for a 4core CPU.

Wow, a wonder happened. The Athlon got now 7 additional WUs (for the next 20 days...).

So this means, the project needs a profile to be set for a PC and without a profile only 1 WU per Core is send out?

I think the work generator isn't keeping up with all the hosts requesting tasks? See here.

No, I have 3 PCs running and only 2 of them had the problem over the last 2 weeks, even at the time where the work generator was fine.
And the one PC where I changed the location/profile has now enough work in the buffer.

Then you need to examine your default profile very closely because it is showing non-standard behaviour

Could you be so kind and have a look at my system 65300, please?
Why do i get only 52 WUs with my 256 Threads?

I'vent any app_config.xml, cc_config.xml or app_info.xml.

I use the school-profil with his default-setting.

Same on system 65301, 65302 and 65303.

Only TN-Grid is running.
