| | Amdahl Corporation - Wikipedia, the free encyclopedia |
 | | Amdahl was a major supplier of large mainframe computers, and later of UNIX and Open systems software and servers, data storage subsystems, data communications products, application development software, and a variety of educational and consulting services. | | | Amdahl Corporation was founded by Dr. Gene Amdahl, a former IBM employee, in 1970, and specializes in IBM mainframe-compatible computer products. | | | Amdahl owed some of its success to antitrust settlements between IBM and the U.S. Department of Justice which assured that Amdahl's customers could license IBM's mainframe software under reasonable terms. |

| | Gene Amdahl - Wikipedia, the free encyclopedia |
| | Gene Myron Amdahl (born November 16, 1922) is an American computer architect and hi-tech entrepreneur of Norwegian descent, chiefly known for his work on mainframe computers at International Business Machines (IBM) and later his own companies. | | | Amdahl also developed a streamlined version of IBM's VM operating system software, further increasing performance. | | | At IBM Amdahl worked on the IBM 704, the IBM 709, and then the Stretch project, the basis for the IBM 7030. |

| | In 1955, Amdahl worked with others to design the Datatron, which led to a computer called the Stretch, and eventually became the IBM 7030, a computer that used the new transistor technology. | | | In 1987, Amdahl founded his third company, this one called Andor Systems after the "and" and "or" logic gates of computer circuitry. | | | Basically, he designed the first computer clones, known then as "plug-to-plug compatibles." Amdahl became the most celebrated entrepreneur in the computer industry for awhile. |

| | In 1967, an IBM designer, Gene Amdahl made the statement that the bottlenecks present in sequential computers would be difficult to overcome because even parallel solutions involved an overhead that is innately sequential and therefore unlikely to be overcome by parallel techniques. | | | We get the formula in the same way as Amdahl's Law with the exception that T(N) is set to one, or, in other words, the problem is scaled up to fit the parallel computer. | | | If we start with a parallel computer, working a problem using N processors will take T(N) = b + (1 - b), or 1, time, since the parallel part, (1 - b), is being performed on all the processors simultaneously. |
