does this restrict BOINC to one CPU ?

   ( intel corei7 920 )

would changing the value to 8 let it use all 8 cpu's ?

the config file looked like this when i first looked at it:

<ncpus>-1</ncpus>

-1 Normally means use default settings. Removing the whole line will surely use the default setting.
This is an debugging feature, but works in real live.
It's intended to test out multicore on a CPU that has less cores.
E.g. set it to 8 on a dual core CPU will behave as a 8 core CPU, starting 8 tasks.

Normally you should use Extra->Boinc Settings -> Processor (other options).
Set "use at most" to 100% to use all cores. E.g. 25% uses only 2 cores on a 8 cores CPU.
