S/390 cluster technology: Parallel Sysplex

This paper describes a clustered multiprocessor system developed for the general-purpose, large-scale commercial marketplace. The system (S/390e Parallel Sysplex™) is based on an architecture designed to combine the benefits of full data sharing and parallel processing in a highly scalable clustered computing environment. The Parallel Sysplex offers significant advantages in the areas of cost, performance range, and availability.

The IBM System/370 vector architecture: design considerations

The considerations that shaped the architecture of the IBM System/370 Vector Facility are reviewed. The architectural requirements, decisions, and innovations are summarized, and the rationale for the choices that were made is given. Issues related to vector function, performance, compatibility, migration, and integration with the rest of the System/370 architecture are covered. >

Concepts of the System/370 vector architecture

This paper discusses the performance, complexity and system-integration considerations that shaped the System/370 Vector Architecture [1, 9]. The architecture is intended for compatible systems providing a range of price and performance. The paper reviews the reasons for choosing a register-oriented architecture with compound instructions over storage-to-storage operations and vector-instruction chaining. Then it discusses the role of cache in stride-N storage accessing, and describes some new facilities introduced for control-program purposes.
