In this paper, we propose a self-boosted co-scheduling(SBCO) algorithm to reduce synchronization latency among consolidated virtual machines. Different from conventional co-scheduling which requires all runnable sibling vCPUs that are from the same VM to be scheduled at precisely the same time, SBCO reorders all these sibling vCPUs threads coarsely at the same level in their respective run queue,...
The purpose of this study is to develop a new system to synchronously control the simulated robot and humanoid robot based on the skeletal tracking technology. This system is a human-robot interaction system. Human can control the robot through the skeletal tracking technology without placing any marker on the subject's body. We use the Microsoft Kinect to get the skeleton framework information of...
Dynamic resource configuration is crucial to the provisioning of service level agreements (SLAs) in cloud computing. Most of today's autonomic resource configuration approaches are designed to scale a single type of resource. A few works are able to partition multiple resources, but mainly to meet the requirement of throughput. Unlike throughput, however, response time behaves nonlinearly with respect...
Cloud elasticity allows dynamic resource provisioning in concert with actual application demands. Feedback control approaches have been applied with success to resource allocation in physical servers. However, cloud dynamics make the design of an accurate and stable resource controller challenging, especially when application-level performance is considered as the measured output. Application-level...
Cloud elasticity allows dynamic resource provisioning in concert with actual application demands. Feedback control approaches have been applied with success to resource allocation in physical servers. However, cloud dynamics make the design of an accurate and stable resource controller more challenging, especially when response time is considered as the measured output. Response time is highly dependent...
