This work is a reference source for the POWER RS/6000 family of workstations. Starting with a comprehensive overview of hardware and software concepts from a user's perspective, the book then focuses on the facilities available in the operating system and hardware subsystems from a systems point of view. The text is suitable for application and systems programmers implementing AIX on RS/6000. It provides detailed discussions of hardware and software features, including: microchannel features in the RS/6000 platform; fixed and floating point architectures; cache memory organization; superscalar implementation; I/O subsystem organization; AIX operating system kernal structure and processes; data flow issues AIX file system design details; AIX memory and process management features; peripheral device configuration; networking interoperability options; CPU layout; and SCSI interface and related protocols. In addition, the book provides essential maintenance, diagnostic, troubleshooting and administrative procedures for the hardware and software subsystems.
