Hi,

I've always been under the impression that the Boinc client (and the processes springing from it) run as "low priority" under Windows.

I've been running Boinc/Setiathome on my I5-3570K. Streaming a radiostation from the internet becomes slow, and even the redrawing of the desktop slows down.

Can someone tell me if I missed a setting or something like that?

Sincerely, Thomas

I've always been under the impression that the Boinc client (and the processes springing from it) run as "low priority" under Windows.

BOINC its own processes (boinc.exe, boincmgr.exe, boinctray.exe, (and if applicable boincsrvctrl.exe)) run at Normal priority.
Project's science applications run at low priority when they are CPU intensive applications, and Below Normal when they are GPU applications and NCI (Non-Computing Intensive) applications.

I've been running Boinc/Setiathome on my I5-3570K. Streaming a radiostation from the internet becomes slow, and even the redrawing of the desktop slows down.

Sounds to me like you're running work on a graphics processing unit, or GPU. In other words, on the graphical processor of your videocard. This can result in slow downs of the computer and more specifically, in slow redraws. Especially when the GPU isn't that high spec'd.
Another possibility is that your system slows down due to (extreme) heat. Have you checked that the fan is spinning? Have you checked that the heat sink isn't clogged up with dust?

My i5-2500K can run work on all 4 cores plus on the AMD HD 7870 without problems, I can even play games on that system at the same time that BOINC runs work (Seti and Einstein). CPU cores run at ~55-60C, GPU runs at 60-65C. Radio Caroline sure doesn't slow down, not on the 64bit nor on the 128bit mp3 lines.

I'd say, check temps first. Install:
- Core Temp to check CPU core temperatures.
- GPU-Z to check GPU temperatures. If applicable, only when you have a GPU and you use it to crunch Seti.

My CPU has an aftermarket cooler on it.
Temps no problem. <60 celcius

I've told the Boinc manager not to use GPU while computer is in use.

After a few hours I can safely say that it doesn't help a 100%, but a hiccup once in a while (say: 2 times per hour) is not something I'll whine about.

It might be an idea to tell users that GPU usage can cause problems like this. Especially with onboard graphics.

Thanks for the info.
