Let me ask another question: Is there a reason to keep a program in 32-bit
mode if it can be ported easily to 64-bit mode (i.e. assume it is portable,
as Richard's)? My programs are usually FLOP or memory bandwidth bound and do
not really need 64 bit integers (but all the reals are 64 bits). As I am
reading, the reason behind the 32-bit mode is for backward compatibility and
ease of migration, and the real thing to do is run in 64-bit mode once you
port the code successfully.
Any suggestions for reading on the subject?
Thanks,
Aleks
