 | | Most mainframes (rumoured to be 90%) have IBM's CICS software installed. | | | Supercomputers are optimized for complicated computations that take place largely in memory, while mainframes are optimized for simple computations involving huge amounts of external data accessed from databases ("mixed workload"). | | | Modern mainframe computers have abilities not so much defined by their performance capabilities as by their high-quality internal engineering and resulting proven reliability, "expensive" but high-quality technical support, top-notch security, and strict backward compatibility for older software. |

| | IBM mainframe - Wikipedia, the free encyclopedia |
| | Mainframe computers traditionally are expensive, physically large, and have high transaction processing and I/O performance, but are not as expensive and high-performance as supercomputers. | | | An IBM mainframe is a large, high-performance computer made by International Business Machines (IBM). | | | In many cases these software subsystems can run on more than one mainframe operating system. |

| | Mainframe is an industry term for a large computer, typically manufactured by a large company such as IBM for the commercial applications of Fortune 1000 businesses and other large-scale computing purposes. | | | Historically, a mainframe is associated with centralized rather than distributed computing. | | | CICS is an online transaction processing program from IBM that, together with the COBOL programming language, has formed over the past several decades the most common set of tools for building customer transaction applications in the world of large enterprise mainframe computing. |

| | Mainframe users were tied to small "dumb terminals," essentially keyboards and monitors with no capacity to compute or process information. | | | The mainframes had the capacity to compute but were slow and could handle only a limited number of users. | | | These computers were fast compared with the mainframe, which usually was slowed due to the number of users logged on from the individual dumb terminals. |

| | MAINFRAMES HAVE STAYING POWER |
| | The operating system on a mainframe was cryptic, requiring a specialized skill set, and it was difficult for ordinary users to get information from the computer. | | | So when minicomputers came on the scene in the 1970s and user-friendly personal computers became widely available in the 1980s, it was thought that mainframes soon would be relegated to the attic to molder with the buggy whips. | | | In the 1990s, according to Saloner, businesses are mixing and matching different computer systems that serve their different needs. |

| | The size of the mainframe’s processor cache is perfectly sized for the mainframe’s processors, as additional cache would have no performance value. | | | The mainframe’s shared cache can be considerably smaller than the dedicated cache on Sun’s servers because of the lower cache missed rate of shared cache systems. | | | Your claim that mainframes have reduced performance because of their “need to provide cache coherency across CPUs,” is likewise incorrect - the fundamental design of shared cache systems eliminates problems with cache coherency. |
