OK, so here's what I'm trying to do. I have two processors. I would like to run 2 projects all the time, one on each processor. Currently I'm attached to two projects but when I do this BOINC still downloads 2 WU for one project and 1 for the other, and rotate between the 3. I'm thinking it'll be something to do with the "switch between projects every X minutes" setting, but I'm not sure if I should set it very high or to 0 to get it to NOT switch between projects.

In case you're wondering, I'm trying to run QCN 100% of the time on one processor, while running rosetta on the other for some numbercrunching.

So, has anyone else tried this? have any suggestions?

Do the two projects have the same resource share?

What's your BOINC version?

Doesn't QCN have "non-CPU-intensive tasks"? That would mean that you have three tasks running on two cores at the same time.

it does indeed have the "non cpu intensive" flag set. Restarted the client and it seemed to notice this and start running all 3 WU at the same time on the two processors.

thanks for the help

where do ou get the : QCN participant USB sensor device from (if you laptop doesn't have/support this) ?

All laptops have an accelerometer to detect excessive vibrations that could damage the hard drive. It's only desktops that require extensions to join QCN

Most newer laptops have an accelerometer built in somewhere. The QCN website lists:


The best way I can think of to see if you have one and if it's compatible, is to download their QCNLive program and see if it finds any sensors to work with.

Ok, so my lappy doesn't have a sensor. And it's not that old (purchased early 2008).

What laptop've you got?

It's a Dell Precision M4300.

those of us using protables in that league do not throw them around - except that guy who said he'd never buy a notebook he cant throw out of his window..

I found two units online, if yours has a biometric reader then it has an accelerometer built in too, if not then no.

@pongley: Ah, didn't know that! Ok, have no biometric reader - so no accelerometer either. *sob sob*
I guess one can't have all...

@Frank: So true... *ROFL*
And for throwing I'd take a netbook, it's more lightweight.

You can buy a sensor from the makers, see here for more information (in German).

It is also said somewhere on QCN site (I don't remember where exactly I read it) that not all manufactures "open" their accelerometers code so other apps can access them... most laptops have it on some way, for instance to control hdd power in case of hard shaking, but QCN are not able to use them ... yet

BTW, I bought an sensor from the merks, and is working fine
