I often need to run Monte Carlo simulations (in C) which involve a lot
of array storage and array scanning/searching operations...  I wonder
what the speed-up would be for those simulations if run under a 64-bit
mode.  Are there any requirements on how the simulations should be
programmed in order to take advantage of the 64-bit arch, or is that
automatically done by the GCC compiler and the kernel?
