    A panel of eight leaders in the fields of supercomputer design and application was conceived by IEEE Spectrum and asked to foretell their technology's future. The panelists described the far-reaching effects of such technologies as: high-speed graphics systems and networks that let users refine designs in real time; more uniform operating systems and sophisticated compilers that will make supercom...

    The differences between optoelectronic and electronic ICs are identified. Crystal growth and device fabrication techniques for optoelectronic ICs are discussed, focusing on their advantages and disadvantages. Two novel devices that exist only as discrete components and will perform even better when integrated with other components on a monolithic chip are highlighted. One is an integrated passive ...

    The author discusses a measure of software reliability and various models for characterizing it, the result of 15 years of theoretical research and experimental application, which are moving into practice and starting to pay off. These tools let developers quantify reliability, give them ways to predict how reliability will vary as testing progresses, and help them use that information to decide w... View full abstract»

    The replacement of the standard series-connected pair of twisted copper wires that connects each home to the telephone network today by optical-fiber cabling that can handle broadband services is discussed. The technologies needed for the fiber to the home, which are dominated by such considerations as bit rates, network architecture, and power dissipation, are discussed. Various combinations of s...

    The competition faced by X-ray lithography from improved optical methods (down to 0.25 mu m) or from a potential breakthrough in fast-electron-beam or ion-beam lithography is examined. The requirements that have to be met for X-ray lithography to become a practical option are discussed. These include a technologically and economically viable source, masks that can withstand the radiation, and lith... View full abstract»
