A hierarchical model of computer organizations is developed, based on a tree model using request/service type resources as nodes. Two aspects of the model are distinguished: logical and physical. General parallel- or multiple-stream organizations are examined as to type and effectiveness-especially regarding intrinsic logical difficulties. The overlapped simplex processor (SISD) is limited by data dependencies. Branching has a particularly degenerative effect. The parallel processors [single…

TLDR
An optimal assignment of swbps r modules, to a two-processor system has been considered by Stone in which the cost of interprocessor communication has been taken into account, in addition to the communication and other collective costs.
Analysis of a Shared Resource MIMD Computer Organization
TLDR
In this paper, a MIMD structure with one shared resource is analyzed for both synchronous and asynchronous request arrivals and it appears that a similar approach can be used to extend the model to more general M IMD cases.
Operating System Structure
TLDR
Characteristics of the resource structure found in the operating system as a mechanism for classifying distributed computer systems are considered, showing that computer networks are easy to develop from uniprocessors in a value-added fashion, but that true network computers are not yet available because development by extending computer network operating systems is not practical.
A Comparative Study of Some Two-Processor Organizations
TLDR
A comparative performance study of four models of two-processor organizations is presented, with the aim being to compare their response times under different workloads and the possibility of switching between alternate organizations in a dynamically reconfigurable system.
Performance evaluation of some computer organisations
TLDR
A simplified model has been analysed for both synchronous and asynchronous request arrivals and results indicate the possibility of selecting an optimum amount of resource replication so that the cost utilisation is optimised.
A new taxonomy for distributed computer systems based upon operating system structure
TLDR
Characteristics of the resource structure found in the operating system are considered as a mechanism for classifying distributed computer systems and the character of the kernel O/S structure needed for future computer systems is defined.

  • 1975
The evolution of hardware organization is traced from early uniprocessor systems with no parallelism through several stages of both single and multiple computer systems each providing a higher degree
Minimization of supervisor conflict for multiprocessor computer systems
TLDR
A methodology is developed through simulation which reduces supervisor queueing by scheduling jobs to processors such that they request the use of the supervisor when the supervisor is predicted to be available.
DISC: dynamic instruction stream computer
TLDR
The Dynamic Instruction Stream Computer is a novel computer architecture which addresses many of the problems present in real-time systems by dynamically partitioning the processor throughput between multiple instruction streams based upon requirement demands.

TLDR
Present trends indicate that future general-purpose computer will be smaller and less costly, but not significantly faster.
Matrix Inversion Using Parallel Processing
TLDR
It is shown that both methods of matrix inversion are indeed able to make effective use of parallel capability, and with reasonable assumptions on the parallelism that is available, the speeds of the two methods are roughly comparable.

TLDR
The high speed computer area seems to be dominated by a continued reduction in the price of computer switching circuits and the approach of these circuits to speeds at which the velocity of light becomes an important factor, so simultaneousity becomes more and more essential if computer performance is to continue to increase.
