In the area of system architecture, there are two most significant trends: multi-core and system virtualization technology. Both of them have quite close relationship with energy efficient computing. Industry turns to integrate more cores on a single chip instead of increasing frequency to solve the heat problem. Meanwhile system virtualization could decrease the total power consumption by sharing...
Aimed at the needs for scheduling real-time tasks in the environment of open real-time system and embedded system, a scheduling mechanism based on messages has been suggested and applied on the Xen virtual machine, and a Multi-Real-Time-Task model based on VCPU is established. Influence on the real-time scheduling is analyzed and solutions will be given. Experiment results prove that scheduling based...
Safety-critical systems have to work correctly and meet time constraints even in the presence of faults. Hardware fault-tolerant technology can provide a high level of reliability, but custom-designed hardware and operating system are too costly to be accepted by most common applications. At present, some research works about hot-spare fault-tolerant systems based on virtualization technology have...
Providing single system image (SSI) on clusters has ever been one of the hot topics in the research field of parallel computer architecture, since SSI supports easier programming and administration on clusters. Currently, most SSI studies focus on the middleware level of clusters, leading to some problems of poor transparence, low performance and so on. This paper presents a novel solution to provide...
It is an important direction of the development of parallel computer architecture to implement single system image (SSI) on clusters, since SSI supports easier programming and administration on clusters. Currently, most SSI studies focused on the middleware level of clusters, leading to some problems of poor transparence, low performance and so on. This paper presents a novel solution to provide SSI...
