Is it possible to declare data types for a cluster profile?

I have an 8-core FX-8320E AMD processor. When I run the "parpool" command, it only creates a pool for 4 cores. I have learned that the processor has 8 integer cores and 4 floating-point cores. My algorithm doesn't have to work on floating-point numbers. Is there any way to create a profile that will allow me to create a pool that will use all 8 cores?
Thanks for your time, and for any input that anyone is willing to provide.

You cannot declare datatypes for a cluster. You can change your code to relentlessly use integer operations, including enclosing all of the constants in appropriate casting, like
X = X + int32(1);
Note: integer division A./B is defined to have the same result as cast(double(A)./double(B), class(A)) which might require a floating point unit.

Thanks so much for your help, including the link which you've provided. It's exactly what I needed.
I knew that the number of cores could be specified, but I didn't think I could just specify 8 since the "parpool" command only showed 4. I also wasn't aware of the "feature('numcores')" command that gives more detail concerning the different types of cores that are available.
After setting the number of cores to 8 in the profile manager, my program runs well now with all 8 cores. I didn't even have to change my data types to integers.
So thanks, once again, for your tremendous help. It's exactly what I needed.
