Thank you for your reply.
I wrote a simple application with GUI. I create a thread to calculate
data which may cost much time. So during the calculation, the interface
can response. But one thread ONLY uses up half of my CPU(dual core)
resource, I need more than two.
The question is coming: where to create the thread? Create one more from
GUI as the previous brother or as the child.

In my opinion, creating another thread from GUI thread or non gui thread
are the same. Am I right?
Yes. Conceptually all threads are "brothers", it doesn't matter which
thread created it, there is no parent/child relationship between them.
The only difference being the "main" thread who is responsible for
the lifetime of the application.
