Number of threads created when a opencl program is run?

Hello,

I have a basic matrix multiplication opencl code and when i run the code with gdb, i see that there is thread creation equal to the number of processing elements in the system

also if i set the max compute units variable to any number, the number of threads created is always the same (=processing elements). Is there any explanation for this and is there a way to control this creation of threads?? thanks in advance.
