The majority of cloud computing consists servers with different configurations which host several virtual machines (VMs) changing resource demands. Additionally, co-located VMs are vulnerable to co-resident attacks (CRA) in a networked environment. These two issues may cause uneven usage within the server and on service, leading performance security degradation. This paper presents an Agent-bas...

The rapid growth in demand for cloud services has led to the creation of large-scale data centers, which allows application service providers lease center capacity deployment as per user requirement terms quality (QoS). These centers consume a lot electrical power contributes increased operating costs and carbon dioxide emissions. In addition, modern computing environments must provide QoS thei...

Linux is widely used on high-performance computing (HPC) systems, from commodity clusters to Cray supercomputers (which run the Cray Linux Environment). These platforms primarily differ in their system configuration: some only use SSH to access compute nodes, whereas others employ full resource management systems (e.g., Torque and ALPS on Cray XT systems). Furthermore, the latest improvements i...

Cloud Computing shares computing resources to execute application. Cloud systems provide high-specification resources in the form of services, leading to the provision of user convenience and greater ease for personal-computer users; however, expansions of the cloudsystem service necessitate a corresponding enhancement of the technology that is used for server-resource management. In this paper...

A method to migrate a task dynamically from a virtual SPMD machine to a virtual SIMD machine is proposed. It is assumed that the SIMD and SPMD virtual machine models only differ to support the different modes of parallelism, and that the program was coded in a modeindependent programming language. The migration pro­ cedure does not require the SPMD PEs to be at the same location in the SPMD pro...

The migration of the execution context has been applied to remote execution and mobile agents, and noncooperative migration can be applied to even more applications, such as load balancing. We have therefore designed a system for the migration of Java threads, one that allows noncooperative and heterogeneous migration of the execution context of the running code. This paper describes an overvie...

The paper focus on Fault Tolerance, a long standing problem in cloud computing by extending Primary Backup model to include cloud features such as virtualization and elasticity. Fault tolerance is a challenging work in Cloud Computing as virtual machines are the basic computing instances rather than hosts that enable virtual machines to migrate to other hosts. The on demand provisioning of reso...

The migration of the execution context has been applied to remote execution and mobile agents, and asynchronous migration can be applied to even more applications, such as load balancing. We have therefore designed a system for the migration of Java threads, one that allows asynchronous and heterogeneous migration of the execution context of the running code. This paper describes an overview of...
