The name is an acronym for Performance Optimization With Enhanced RISC. [1] The ISA is used as base for high end microprocessors from IBM during the 1990s and were used in many of IBM's servers, minicomputers, workstations, and supercomputers. These processors are called POWER1 (RIOS-1, RIOS.9, RSC, RAD6000) and POWER2 (POWER2, POWER2+ and P2SC).
Underlying ISPF/PDF is an extensive set of tools that allow application developers to create panel-driven applications, and a set of guidelines to promote consistent use of ISPF functions. A "panel" is a character-based "window" which can encompass all or part of a 3270 session's screen real estate.
In 1974 IBM started a project to build a telephone switching computer that required, for the time, immense computational power. Since the application was comparably simple, this machine would need only to perform I/O, branches, add register-register, move data between registers and memory, and would have no need for special instructions to perform heavy arithmetic.

On April 8, 2014, in honor of the 50th anniversary of the System/360 mainframe, IBM announced [23] the release of its first converged infrastructure solution based on mainframe technology. Dubbed the IBM Enterprise Cloud System, [ 24 ] this new offering combines IBM mainframe hardware, software, and storage into a single system and is designed ...
hiperspaces (High performance space). [21] [22] These spaces are similar in that both are areas of virtual storage that a program can create, and can be up to 2 gigabytes. Unlike an address space, a dataspace or hiperspace contains only user data; it does not contain system control blocks or common areas.
IBM's Hierarchical File System (HFS) is a POSIX-style hierarchical file system [1] for the MVS/ESA/SP through z/OS operating systems.. IBM introduced HFS on February 9, 1993 in MVS/ESA System Product Version 4 Release 3 OpenEdition [2] [3] with DFSMS/MVS Version 1 Release 2 [4] for 3090 mainframes.
SMF data can be collected through IBM Z Operational Log and Data Analytics and IBM Z Anomaly Analytics with Watson. IBM Z Operational Log and Data Analytics collects SMF data, transforms it in a consumable format and then sends the data to third-party enterprise analytics platforms like the Elastic Stack and Splunk, or to the included operational data analysis platform, for further analysis.
