Topic 197542

I'd just like to point out that the "Gravitational Wave S6 Directed Search (CasA) 1.08" tasks use an entire CPU thread, not just 50% as the "0.5 CPUs + 1 NVIDIA GPU" suggests.
That's a bit annoying on my setup, because I allowed BOINC to use 50% of my 4 CPU threads 100% of the time. (Core 2 Quad Q8300 here) Apparently BOINC thinks it's ok to squeeze in any number of tasks that use less than 100% of a core while already running two full-time CPU tasks. And since the S6 Directed Search actually uses an entire thread as well, I'm essentially running at 75% instead of just a bit above 50%.

Can I adjust the estimated CPU usage of this particular task type somehow so BOINC doesn't think it can run that regardless of other CPU tasks? I only see a GPU usage option on the project preferences page.

Yes, by creating a app_config.xml file.
Assuming your running Windows then open notepad (if not then use a plain text editor) and copy the following into it:
[pre]


einstein_S6CasA

1
1


[/pre]
Then save the file as app_config.xml and make sure that it's NOT named app_config.xml.txt somewhere easy to find.
When done copy/move the file to the project folder under the Boinc data directory. (boinc\projects\einstein.phys.uwm.edu)
The location of the data directory can be found in the startup messages in the Event log (Ctrl+Shift+E)
Then open Boinc Manager and in advanced view look for the dropdown menu called "Advanced" and click on "Read config files". If done right the new settings should take effect immediately, although the text (0.5 CPUs + 1 NVIDIA GPU) might still be wrong until Boinc is restarted or a new task starts up, but Boinc should suspend on of the runing CPU tasks so that no more than 2 tasks are running.

If something is unclear do ask again! =)

Thanks, that's exactly what I

Thanks, that's exactly what I wanted to know.
