A superminicomputer (Interdata 7/32) preserved in a museum. A superminicomputer, colloquially supermini, is a high-end minicomputer. [1] The term is used to distinguish the emerging 32-bit architecture midrange computers introduced in the mid to late 1970s from the classical 16-bit systems that preceded them.
This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has ...
For example, the computers behind the first Space Shuttle simulator consisted of thirty-six 32-bit minis inputting and/or outputting data to networked mainframe computers (both IBM and UNIVAC), all in real-time. The 8/32 was used in the Lunar and Planetary Laboratory, Department of Planetary Sciences at the University of Arizona for research ...
The term supercomputer itself is rather fluid, and the speed of today's supercomputers tends to become typical of tomorrow's ordinary computer. Supercomputer processing speeds are measured in floating-point operations per second, or FLOPS. An example of a floating-point operation is the calculation of mathematical equations in real numbers.
Mainframes and supercomputers cannot always be clearly distinguished; up until the early 1990s, many supercomputers were based on a mainframe architecture with supercomputing extensions. An example of such a system is the HITAC S-3800 , which was instruction-set compatible with IBM System/370 mainframes, and could run the Hitachi VOS3 operating ...
The appearance of even lower-priced scientific workstations (e.g., Dana Computer/Ardent Computer/Stellar Computer (the merger of these companies)) based on microprocessors with high performance floating point units (FPUs) during the 1990s (such as the MIPS R8000, IBM POWER2), and Weitek eroded the demand for this class of computer.
The Cyber 18 is a 16-bit minicomputer which was a successor to the CDC 1700 minicomputer. It was mostly used in real-time environments. One noteworthy application is as the basis of the 2550—a communications processor used by CDC 6000 series and Cyber 70/Cyber 170 mainframes. The 2550 was a product of CDC's Communications Systems Division, in ...
An incompatible small computer, the IBM 1130 introduced the following year, was designed for scientific and engineering computing. The design of the Model 20 was the result of a tug of war within IBM. John Haanstra had wanted a low-end machine that could execute IBM 1401 instructions. Fred Brooks wanted the machine to have System/360 architecture.
