My old laptop had aa Intel P4 cpu (32 bit) and I got a new one
with and Intel I5 (4 cores) cpu (64 bit).
I had compiled a C++ math app on my P4 laptop with
g++ <source_code> -o <executable_name>
It run fine on the I5....but
Since the I5 is 64 bits, and I have 6GB of mem
(using the 22.214.171.124-pclos3.pae.bfs kernel)
I want the arrays in the app to extend beyond the
32 bit limit imposed by the P4 compilation.
So, can I recompile the source with g++ to take
full advantage of the memory space and 64-bit registers
even though the PCLOS 2011.6 is a 32-bit compile?
I want the arrays in the app to be larger than 4GB,
and be able to do math on 64-bit numbers, and store them
