Computer Evaluation and Performance Measurement

Computer Evaluation

Computer evaluation, comparison, and selection is a decision-making process that relies on a variety of performance indicators, which are obtained through the computer performance measurement procedure. The evaluation procedure should be conditioned by the decision-making process to ensure the most appropriate selection of a computer system. This article delves into the aspects of computer performance measurement and evaluation within the context of computer evaluation, comparison, and selection.

Elementary Criteria for Performance Evaluation

The performance evaluation process begins with a set of elementary criteria for performance evaluation. These criteria are used to measure the computer system's performance in various aspects, such as monoprogramming performance, multiprogramming performance, and multiprogramming efficiency. The corresponding set of performance indicators is defined based on these criteria.

Monoprogramming Performance Measurement

Monoprogramming performance measurement assesses the computer system's ability to perform a single task without interruption or interference from other tasks. This measurement is crucial for determining the effectiveness of a computer system in handling complex tasks that require full system resources.

Multiprogramming Performance Measurement

Multiprogramming performance measurement evaluates the computer system's ability to handle multiple tasks simultaneously. This measurement considers factors such as context switching, task scheduling, and resource allocation. It is essential for assessing the computer system's efficiency in managing multiple tasks concurrently.

Multiprogramming Efficiency Measurement

Multiprogramming efficiency measurement determines the effectiveness of the computer system in managing multiple tasks while utilizing available resources optimally. This measurement considers factors such as the degree of multiprogramming, resource utilization, and system overhead. It is crucial for assessing the computer system's overall efficiency in managing multiple tasks.

Numerical Examples

The applicability of the proposed elementary criteria is illustrated through numerical examples. These examples demonstrate the practical application of the performance measurement procedure in evaluating and comparing different computer systems based on their performance indicators.

Conclusion

Computer evaluation, comparison, and selection are crucial processes that require a thorough understanding of computer performance measurement and evaluation. By following a standardized set of synthetic benchmark programs and measuring performance indicators based on elementary criteria for performance evaluation, it is possible to make informed decisions about the selection of a computer system. This approach ensures that the selected computer system is optimally suited to meet the specific needs of the user, whether it be for business, technical, scientific, industrial, or military applications.
