“In the arena of high-performance computing, 64-bit processing has always been the de-facto. All the supercomputers we facilitate for production here at the GSIC Center, Tokyo Institute of Technology, are 64-bit architecture machines. This is due to tremendous demand for large volumes of data being processed for multitudes of high-end and leading-edge scientific applications---a single application may consume 10s to 100s of Gigabytes of memory, and we expect that the next generation of applications in the next several years will require Terabytes. Moreover, high-end applications on desktops of tomorrow resemble high-end scientific applications of today; for example, physical simulations of entities in games, as well as graphics and sound capabilities, are increasingly exploiting advanced algorithms that essentially resemble what are being run on supercomputers today, with computing and data volume requirements that will likely scale to current-day supercomputing requirements in the very near future. As such, we deem 64-bit computing will quickly become the norm to facilitate the exciting applications that will likely be available for people at large, not just being restricted to advanced research by specialists, such as scientists and engineers.”
