Notable exceptions include IBM mainframes, which support IBM's own format ( in addition to the IEEE 754 binary and decimal formats ), and Cray vector machines, where the T90 series had an IEEE version, but the SV1 still uses Cray floating-point format.

Current mainframes in IBM's line of business computers are developments of the basic design of the IBM System / 360.

Software upgrades usually require setting up the operating system or portions thereof, and are non-disruptive only when using virtualizing facilities such as IBM's Z / OS and Parallel Sysplex, or Unisys ' XPCL, which support workload sharing so that one system can take over another's application while it is being refreshed.

Most such editors are derivatives of XEDIT, IBM's editor for VM / CMS.

While there are other industrial-strength transaction processing systems, notably IBM's own CICS and IMS, TPF's raison d ' être is extreme volume, large numbers of concurrent users and very fast response times, for example VISA credit card transaction processing during the peak holiday shopping season.

Typically third party software packages such as IBM's TPF Tool Kit or Step by Step Trace from Bedford Associates or CMSTPF, TPF / GI, zTPF / GI from TPF Software Inc. are employed to aid in the tracing and tracking of errant TPF code.

IBM's line of Deskstar hard drives ( and to a lesser extent Hitachi's ) are colloquially referred to as " Deathstars ", especially the very unreliable 60GXP and 75GXP models.

The POWER series microprocessors are used as the CPU in many of IBM's servers, minicomputers, workstations, and supercomputers.

IBM's POWER-based processor boards and the workstation-level Intel-based Xeon processor boards, for example, have multiple CPUs, more on-die cache and ECC memory, which are features more suited to demanding content-creation, engineering and scientific work than to general desktop computing.

In IBM's OS / 360 and its successors they are referred to as partitioned data sets.

IBM's own 3101 and 3151 ASCII display terminals are examples of this.

The IBM origin of the numbering scheme is reflected in the fact that the smallest ( first ) numbers are assigned to variations of IBM's EBCDIC encoding and slightly larger numbers refer to variations of IBM's extended ASCII encoding as used in its PC hardware.

IBM's current assignments are listed in their CCSID repository.

However, proprietary transaction-processing environments such as IBM's CICS are still very popular, although CICS has evolved to include open industry standards as well.

The SCO Group asserted that there are legal uncertainties regarding the use of the Linux operating system due to alleged violations of IBM's Unix licenses in the development of Linux code at IBM.

Thus, the definition of IBM's " corporate mission " in the 1940s might well have been: " We are in the business of handling accounting information need for the larger US organizations group by means of punched cards.

IBM's and Hewlett Packard's main Southern Africa and South Africa offices are in Rivonia, Sandton.

Various add-on modules are provided for interfacing, e. g., to GNU Octave, OpenDX ( IBM's scientific visualization software ), Tcl / Tk and ODBC.

Some high-level assemblers are Borland's TASM, NASM, Microsoft's MASM, IBM's HLASM ( for z / Architecture systems ), Alessandro Ghignola's Linoleum, and Niklaus Wirth's PL / 360.

CICS provides the same run-time container as IBM's WebSphere product family so EJB applications are portable between CICS and Websphere and there is common tooling for the development and deployment of EJB applications.

IBM's zSeries revenues are actually increasing despite declining prices.

Unlike prior models, these Fujitsu systems are not compatible with IBM's and cannot run z / OS, but the announcement has customers wondering if Fujitsu will take the next step in re-entering the ( now growing ) market.

This technical leadership and the rivalry with IBM was emphasized when the Systempro server was launched in late 1989-this was a true server product with standard support for a second CPU and RAID, but also the first product to feature the EISA bus, designed in reaction to IBM's MCA ( MicroChannel Architecture ).

The IBM 3270 display terminal subsystem was designed and developed by IBM's Kingston, NY, laboratory ( which later closed during IBM's difficult time in the mid-1990s ).

AltiVec is a floating point and integer SIMD instruction set designed and owned by Apple, IBM and Freescale Semiconductor, formerly the Semiconductor Products Sector of Motorola, ( the AIM alliance ), and implemented on versions of the PowerPC including Motorola's G4, IBM's G5 and POWER6 processors, and P. A.

Although both the consumer desktop and the workstation benefit from CPUs designed around the multicore concept ( essentially, multiple processors on a die, the application of which IBM's POWER4 was a pioneer ), modern workstations typically use multiple multicore CPUs, error correcting memory and much larger on-die caches than those found on " consumer-level " CPUs.

Business System 12, or simply BS12, was one of the first fully relational database management systems, designed and implemented by IBM's Bureau Service subsidiary at the company's international development centre in Uithoorn, Netherlands.

Since the PC architecture was well documented in IBM's manuals, and PC DOS was designed to be similar to earlier CP / M operating system, the PC soon had thousands of different third-party add-in cards and software packages available.

A major feature of the system was its ability to run programs that were designed to run on IBM's mainstream operating system ( MVS ).

It is based on IBM's PL / I language, and was designed in the early 1970s.

The IBM Personal Computer AT, more commonly known as the IBM AT and also sometimes called the PC AT or PC / AT, was IBM's second-generation PC, designed around the 6 MHz Intel 80286 microprocessor and released in 1984 as machine type 5170.

Feistel networks were first seen commercially in IBM's Lucifer cipher, designed by Horst Feistel and Don Coppersmith in 1973.

The 8100 also supported a terminal called the 8775 ( which shared the same case as the 3279 colour display terminal for IBM's mainframes and, like the 3279 was designed at IBM's UK Development Lab at Hursley Park, England ) which was the first to ship with the ability to download its functionality from the host computer to which it was attached.

It was designed to operate a text printer that used IBM's 8-bit extended ASCII character set.

Three implementations of the FS architecture were planned: the top-of-line model was being designed in Poughkeepsie, NY, where IBM's largest and fastest computers were built ; the middle model was being designed in Endicott, NY, which had responsibility for the mid-range computers ; and the smallest model was being designed in Rochester, MN, which had the responsibility for IBM's small business computers.

* He designed a revolutionary address translation system, the " Blaauw Box ", which was removed from the original System / 360 design, but was later used in IBM's unsuccessful proposal to MIT's Project MAC.

The initial structure was designed by Eero Saarinen, who clad the structure in blue panels of varying hues after being inspired by the Minnesota sky, as well as IBM's nickname of " Big Blue ".

IBM's initial answer was OfficeVision / 2, a server-requestor system designed to be the strategic implementation of IBM's Systems Application Architecture.

For example, one of IBM's FORTRAN compilers ( H Extended IUP ) had a level of optimization which reordered the machine code instructions to keep multiple internal arithmetic units busy simultaneously.

An alternative view of IBM's actions, born out of the belief that corporations maintain consistent strategies over the short and medium term despite executive changes, is that IBM acquired Sequent not to nurture it but simply to keep it out of Sun's clutches.

IBM's solution was provided by quarter-inch cartridge ( QIC ) magnetic tape drives that use standard DC300 cartridges to store 204 Kbytes.

The IBM 729 Magnetic Tape Unit was IBM's iconic tape mass storage system from the late 1950s through the mid 1960s.

Starting in the late-1960s IBM's lab in Boulder, Colorado began development of a low-cost mass storage system based on magnetic tape cartridges.

The company originally challenged IBM's dominance in tape storage, and expanded to compete in the printer business for more than a dozen years.

IBM's prior technology employed 9 recording tracks with a data density of 6, 250 bytes per inch of tape, so the 3480 format was greeted as a major breakthrough.
