Performance Evaluation And Tests Of Real-time Cluster System

The benefit of Cluster computing with COTS components has been cognized from its applications. With the quickly increasing information in diverse military systems such as command and control, radar/image signal processing, physical simulating, the computing platforms in these systems are desired with well scalability, availability, persistiveness and performance-price ratio. In these platforms, all of hard deadline must be satisfied; the platforms never fail in a long life term. From viewpoint of technology, the information processing in these applications could be classified as real-time parallel computing in ontrolling loops.Real-time parallel system not only requires high throughput, response time constraints and demands hard life cycle not lapse features. Real-time system from the bottom usually parallel hardware, operating system software, parallel computing platforms and software applications upper four parts. Application layer dependent on parallel computing platforms, although there are some time to meet the requirements of the certification application whether algorithms, but these methods are based on real-time clustering platform basis. In the face of real-time applications developers and users demand these assessment methods have inherent deficiencies, the need for real-time parallel / distribution environment means a corresponding fall.In parallel group design parallel / distributed system architecture, targeted to address key point to take appropriate measures and mechanisms, optimizing the design results;in the certification stage assessment methods for the measurement of system performance information repeatedly refine and improve the system components, thereby obtaining satisfactory results. The object to the application characteristics as a starting point, according to the level of the cluster system behaviour, the types of clusters in real time by a system of assessment.To determine whether a cluster system is real-time, the need for an analysis of the system architecture and enabling technology. By analysing system architecture technology...
