64-bit systems appeared more than 10 years ago, but we became closely acquainted with them comparatively recently when they came to the mass computer market. More and more software developers talk about the necessity of the support of such systems. Formerly 64-bit processors were mainly spread in the field of prolonged and complicated calculations - computational modeling of hydrodynamics and flow dynamics processes, deformable solid body mechanics, ecology and molecular chemistry ones, etc. They were also used for the maintenance of some ultra-large data bases. But today systems based on these processors can be observed as typical work stations. So, is it really necessary to port the applications to the 64-bit platforms? And if the decision of the porting is made, then by what means can it be done with the least time and financial costs? Let us see.
