multicore processing question

[Zepeda, Herbey]

Hi, 

I'm relatively new to FreeBSD and have had a hard time get to the right information relating multicore processing. I hope someone can give me some pointers.

I have a two core processor and FreeBSD (latest stable release).

Question:

If I have a c program that creates child processes with fork and exec (in a non blocking way), will the child processes be executed by FreeBSD in parallel using the different cores without me having to do special synchronization arrangements to my program?

Will I need threads instead of processes? 

thanks
