Sorry, couldnt figure out how to search the forums.

I got a 2 cpu Xeon system with hyperthreading on a Windows OS. I like to get 4 instances on BOINC to run.


When I attach the project, I can only get two work units to start. Is there a way to get 4 units to run at one time?

Thanks!

The answer you seek lies in your general preferences.
"On multiprocessors, use at most" defaults to 2, if I remember correctly. Change it to 4 and your dual Xeon will have a wu per cpu.

I would caution you that in the event of something happening to your system, you may then lose 4 wu's, instead of 2. Perhaps you should establish the stability of your platform first?

Choose wisely. :)

You also need about 600 - 700 MB / Workunit in allocated diskspace. That's also under the general preferences.
4 GB should do it...
