In attempting to run "average" and "long" tasks on multiple threads I have set my app_config to

<app_version>
<app_name>srbase5</app_name>
<cmdline>-t4</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>
<app_version>
<app_name>srbase6</app_name>
<cmdline>-t4</cmdline>
<avg_ncpus>4</avg_ncpus>
</app_version>

And then restarted Boinc. Boinc allocates 4 threads to the task but the task only runs on one thread not 4 as desired leaving the other 3 threads running idle.

Removed the avg_ncpus. Now Boinc allocates only one thread and the task only runs on one thread...so the result is the same as if I never set up the app_config.

Maybe you can try to restart your computer? Or go to option -> read config files in Boinc manager.

I don't know what is wrong with the client either...


On one of my computers (Win 7 / Intel) I added back the avg_ncpus, then made the changes to the cc_config file and now things are running as expected...

However, the other computer (Win 10 / Ryzen) is still not working right after making the readjustments.

I still haven't solved the problem for the Win 10 computer. However for for the one machine that seems to be working with the multithread.....why is the run time the same (or nearly so) as the CPU time? Rather than run time around 1/4 of CPU time.

Since my comment on run time, the reported run times of my tasks are now equal to the time between task sent and task received by the server.... and unfortunately not the time that the task took to run.
