Multi-CPU User's Guide

This document, the "Multi-CPU User's Guide" (EK-MULCP-UG-001, published December 1981), serves as a reference for operators, system administrators, and Digital Field Service personnel regarding systems configured with multiple KL10-D (1090) CPUs.

Key contents include:

• Product Description: An overview of the Multi-CPU system, which utilizes shared memory and a single copy of the TOPS-10 operating system to improve capacity and performance, supporting up to 300 active jobs.
• System Specifications: Provides electrical, mechanical, and environmental requirements, noting that Multi-CPU configurations have specific electrical demands dependent on the number of CPUs.
• System Considerations: Details configuration rules, including the role of the "policy CPU," the necessity of dual-ported disk drives, and the setup of MH10 core memories. It includes diagrams of various configurations (memory, disk, and tape drive setups) and information on maintaining a "stand-alone mode" for testing.
• Software Overview: A high-level description of the TOPS-10 operating system's features in a multi-CPU environment, including multiprogramming, job scheduling, batch processing, and synchronous communications.
• Installation: A step-by-step guide for installation and cabling, including site preparation, unpacking, deskidding, power-up procedures, and hardware acceptance testing requirements.
