[R] Opening more than 1 R console in Windows

Hi all,

I recently found out that R does not utilize fully the Duo Core capability when you only run one instance of R.
I did some number crunching today and it seems that if I only open 1 R console, it uses 50% of my CPU (either 50-50 or 100-0 on 2 cores).

Then, I open the second instance and divide the work into two parts, and run them parallelly, they seems to utilize 100% of my CPU.

So, my question would be that: is the computing result the same if I do them this way? Will there any mistake compared to running only one instance at a time?

Thank you all.
