This is a four-color brochure for the CRAY X-MP series of computer systems. The front cover has a color photograph of a Cray X-MP computer system on a yellow tile floor. The company logo is on the top right corner. The first part is about introducing the Cray X-MP series of computer systems. The Cray X-MP is a multi-processor system. The mainframe features two CPUs (Central Processing Units) and a multiport memory. Following is about the Cray X-MP hardware features. The X-MP has a 16-gate array integrated circuits, four parallel memory access ports per processor, and is in scalar and vector modes. Included in this section is a colored diagram of the Cray X-MP overall system organization. Following is about the Cray X-MP software features. There is a Cray Operating System (COS) which supports concurrent independent uniprocessor jobs and multiprocessing for a single job. Multiprocessing can be initiated and controlled by FORTRAN. Following is a section that lists the basic hardware components for the Cray X-MP Models 22 and 24. Subsections include Two Central Processing Units (CPUS); Central Memory; Input/ output channel configuration; I/O subsystem (IOS); optional Solid-state Storage Device (SS); Peripheral Expander; Power and cooling equipment; One standard; two optional front-end interfaces. Included in this section is a colored diagram of the hardware components for the X-MP Models 22 and 24. Following is a section highlighting the features of the X-MP computer system. Included in this section is a colored diagram that lists the hardware features of the X-MP and illustrated the SSD, mainframe and IOS. Following is a section about the software for the Cray X-MP. Software products supported by the system include Cray Operating System (COS); FORTRAN Compiler CFT); Cray assembler Language (CAL). Included in this section is a color photograph of a woman at her desk, typing on computer. Following is a section about the design of the Cray X-MP. Subsections include The Cray X-MP Mainframe; Physical Characteristics of the Cray X-MP Mainframe; CPU Computation Section; CPU Control Section; CPU Intercommunication Section; Central memory I/O Section; I/O Section; I/O Subsystem; Solid-state Storage Device (SSD); Interfaces to Front-end Computers; Configurations; Cray X-MP Maintenance; Cray X-MP Reliability. Included in this section is a colored system diagram. The inside back cover has a color photograph of the Cray X-MP.
