64-bit Product

The PSCAD 64-bit product is identical to its 32-bit version counterpart, except that it is compiled as a 64-bit application. It directly addresses the ‘Out of memory’ issue that some power users have experienced when attempting to run very large simulations: If a simulation exceeds the allocated process memory of 2 GB (imposed by the Windows 32-bit operating system) then the simulation will crash, resulting in lost time. It is important to note that although a 64-bit application will open up an enormous memory space (4 TB or 4,000 GB) the speed of execution is not affected. That being said, any machine that may be constrained by memory limits may see a big speed improvement with the added room: Speed improvements are tied to the memory loading, rather than the memory capacity.
