The key difference between 32-bit and 64-bit computing is the 64-bit computer can use more system memory. Windows XP Professional x64 Edition supports up to 128 gigabytes (GB) of RAM and 16 terabytes of virtual memory, allowing applications to run faster when working with large data sets. Physical memory support will grow in the future as hardware capabilities expand.
The release of processors supporting dual 32-bit/64-bit processing has opened the door for a transition to 64-bit operating systems and native 64-bit processing applications.
OptiFDTD 7.1 is the first Optiwave product optimized to support multicore processors and multiprocessor configurations for maximum performance and scalability. Multicore/multiprocessor workstations can benefit from increased simulations speeds where complex OptiFDTD simulations can run up to 10x faster than a normal desktop.
