how can i control the number of running processes/tasks? right now there are 3 running process, that's too much. 1 of processes is does nothing, it just occupy the memory. Why it isn't terminated when no such task is computed?
There are two tasks running now, how can i set to compute only one task?
i have 6.12.33 on athlon 64, win 64
thanks

Set "On multiprocessors, use at most N of the processors" and "On multiprocessors, use at most X% of the processors" to set the amount of processors (minimum and maximum).

You can set these options through most project's global preferences, or when you use the local preferences, set "N" through the project web preferences and X% through the local preferences.

Without you telling what exactly you see, where you see this and what the names are or the project or projects you allow BOINC to visit for work, there's not much I can say about the "3 processes" thing. It's possible a task hangs, it's possible that what you see is a wrapper application, without more information I can't comment on that.

now there's only one task running
i have unchecked that checkbox
when it happens again, i will post the process names

there's another thing, i have set to use only 20% of memory, but each of that processes used that amount itself. i have 3gb ram and all 3 processes used 900gm ram which is too much. maybe you are right and the third process just hanged
i guess i just set it to 10% in case it happens again
thanks for tips
