POWER9 is a family of superscalar, multithreading, multi-core microprocessors produced by IBM, based on the Power ISA.It was announced in August 2016. [2] The POWER9-based processors are being manufactured using a 14 nm FinFET process, [3] in 12- and 24-core versions, for scale out and scale up applications, [3] and possibly other variations, since the POWER9 architecture is open for licensing ...
[3]: 9 Because of the gaps and other information, the recorded space is larger than that required for just the count data, key data, or user data. IBM provides a "reference card" for each device, which can be used to compute the number of records per track for various key and data field sizes, and to optimize the capacity of the device. [4]
In computing, a signed overpunch is a coding scheme which stores the sign of a number by changing (usually) the last digit. It is used in character data on IBM mainframes by languages such as COBOL, PL/I, and RPG. [1] Its purpose is to save a character that would otherwise be used by the sign digit. [2]
Products, services, and subsidiaries have been offered from International Business Machines (IBM) Corporation and its predecessor corporations since the 1890s. [1] This list comprises those offerings and is eclectic; it includes, for example, the AN/FSQ-7, which was not a product in the sense of offered for sale, but was a product in the sense of manufactured—produced by the labor of IBM.
Fixed-block architecture (FBA) is an IBM term for the hard disk drive (HDD) layout in which each addressable block (more commonly, sector) on the disk has the same size, utilizing 4 byte block numbers and a new set of command codes. [1]
SVC is a two byte instruction with the hexadecimal operation code 0A; the second byte of the instruction, the SVC number, indicates the specific request. [2] The SVC number can be any value from 0 to 255, with the particular SVC number being up to the implementer of the operating system, e.g. on IBM's MVS, SVC 3 is used to terminate a program, while on the UNIVAC VS/9 and Fujitsu BS2000 ...
IBM enhanced one of GM-NAA I/O's successors, the SHARE Operating System, and provided it to customers under the name IBSYS. [1] [2] As software became more complex and important, the cost of supporting it on so many different designs became burdensome, and this was one of the factors which led IBM to develop System/360 and its operating systems ...
