Hello, if I let Boinc compute, my ressource monitor only shows 12 to 20% CPU Usage, why? My Configuration:

GenuineIntel
Intel(R) Core(TM) i7 CPU 920 @ 2.67GHz [Family 6 Model 26 Stepping 5]
(8 Prozessoren)

AMD ATI Radeon HD 5800 series (Cypress) (1024MB) driver: 1.4.696

Microsoft Windows 7 Ultimate x64 Edition, Service Pack 1, (06.01.7601.00)

Does it not use all of my Prozessors? (4 physical 4 virtual i guess)

Windows Task Manager and Resource Monitor will show a maximum of 99% when all cores are being used, so in your case this is 99 / 8 = ~12%. When more than one core is being used by one application, it'll show a max of 24%.

This is a Windows thing, not BOINC, not Seti.

How many tasks run at once?

Each task from SETI@Home will run on one core (and show 12% usage on that core).

BOINC WIKI

Ok, only one BOINC is running. If I want to start another, he requests a Computer name and password?

Normally, only one BOINC can run at a time. You can start multiple BOINC Managers, one for each client you want to monitor, on a network. That's why it asks for the computer name or IP address and the password of that computer.

To run two BOINC on one computer, you'll need to run with the --allow_multiple_clients switch and give both clients a different RPC port. See this thread at the BOINC forums for the whole low-down. It's not easy to do.

So the next question would be, why would you want to start BOINC more than once? What are you trying to achieve?

And that should be enough. This one BOINC client should start as many tasks as CPU cores (and GPUs) are available.

If less tasks are started than you deem appropriate, please restart the BOINC client (not only the manager) or reboot your computer and then post the first 20 to 30 lines of the startup messages from the BOINC event log here.

Computer sind nicht alles im Leben. (Kleiner Scherz)

SETI@home classic workunits 3,758
SETI@home classic CPU time 66,520 hours

The tasks are separate executables that have fairly long names in most cases.

I just thought it would be a good idea to use more than one of my CPU Cores I have in my system. But I dont think I will manage to do this if even YOU say that it is not easy :)

OK I see, use max CPUs is set to 1 - looked it up in my preferences but could not find this option oO

EDIT

Hah I had to tell him to use a percentage of my processors, now I am calculating 2 tasks at once (2 cores active now). Strangely this setting was set to 25%, I have 8 cores, shouldnt he then already use 2? Set it to 50% and now BOINC is running 2 tasks at once. Shouldn't this already be 4? Or has this to do with the 4 virtual and 4 physical Cores? I guess so...

EDIT

Hmm the messages windows tells me "max CPUs used: 4" but 2 tasks active...

EDIT

Another strange thing:

08.02.2012 14:40:38 | | don't compute while active
08.02.2012 14:40:38 | | don't use GPU while active

I have set it to always compute in the menus, and BOINC IS always computing...

EDIT

Ok sorry now all is working fine, I have 4 active tasks with 50% CPU Usage.

Means that you are short of work on your computer, and S@H is short of work to hand out at the server.
