MIPS (Microprocessor without Interlocked Pipelined Stages) [1] is a family of reduced instruction set computer (RISC) instruction set architectures (ISA) [2]: A-1 [3]: 19 developed by MIPS Computer Systems, now MIPS Technologies, based in the United States.
A mainframe computer, informally called a mainframe or big iron, [1] is a computer used primarily by large organizations for critical applications like bulk data processing for tasks such as censuses, industry and consumer statistics, enterprise resource planning, and large-scale transaction processing.
zMIPS refers to the MIPS measure used internally by IBM to rate its mainframe servers (zSeries, IBM System z9, and IBM System z10). Weighted million operations per second (WMOPS) is a similar measurement, used for audio codecs.
IBM enforces an MSU rule called the “technology dividend”: each new mainframe model has a 10% lower MSU rating for the same level of system capacity. For example, when IBM introduced the System z9 -109 in 2005, if a particular z9 configuration could process the same number of transactions per second as its predecessor (a particular z990 ...
The result was the definition of a "VAX MIPS", the speed of a VAX-11/780; a computer performing at 27 VAX MIPS would run the same program roughly 27 times faster than the VAX-11/780. Within the Digital community the term VUP ( VAX Unit of Performance ) was the more common term, because MIPS do not compare well across different architectures.
IBM Z Development and Test Environment can be used for education, demonstration, and development and test of applications that include mainframe components. The Z390 and zCOBOL is a portable macro assembler and COBOL compiler, linker, and emulator toolkit providing a way to develop, test, and deploy mainframe compatible assembler and COBOL ...
In IBM System z9 and successor mainframes, the System z Integrated Information Processor (zIIP) is a special purpose processor.It was initially introduced to relieve the general mainframe central processors (CPs) of specific Db2 processing loads, but currently is used to offload other z/OS workloads as described below.
In the early 1990s, MIPS began to license their designs to third-party vendors. This proved fairly successful due to the simplicity of the core, which allowed it to have many uses that would have formerly used much less able complex instruction set computer (CISC) designs of similar gate count and price; the two are strongly related: the price of a CPU is generally related to the number of ...
