In the virtualization technique, numbers of different components are involved to manage the network, storage, memory. Live migration is the key concept in which the live or active virtual machine is migrated from one host to another host i.e. physical server without disturbing the live environment and the services. This feature is useful for handling the different tasks like power management, I...

The High Performance Computing (HPC) field is witnessing a widespread adoption of Graphics Processing Units (GPUs) as co-processors for conventional homogeneous clusters. The adoption of prevalent SingleProgram Multiple-Data (SPMD) programming paradigm for GPU-based parallel processing brings in the challenge of resource underutilization, with the asymmetrical processor/co-processor distributio...

Nowadays, it is an important trend in the system domain to use the software-based virtualization technology to build the execution environments (e.g., the Clouds). After introducing the virtualization layer, there exist two schedulers: One in the hypervisor and the other inside the Guest Operating System (GOS). To fully understand the virtualized system and identify the possible reasons for per...

The purpose of this paper is to propose a visualization framework for container supply chain by modern information technologies. The concept of container supply chain is studied. The approaches of modeling and visualizing container supply chain are discussed. The model of container based data acquisition is studied. A holistic framework of visualizing container supply chain is built. The paper ...

Network virtualization provides the ability to run multiple concurrent virtual networks over a shared substrate. However, it is challenging to design such a platform to host multiple heterogenous and often highly customized virtual networks. Not only high degree of flexibility is desired for virtual networks to customize their functions, fast packet forwarding is also required. This paper prese...

for enterprise data centers. The ability to consolidate infrastructure and dynamically manage workloads delivers high value, both through cost savings and increased business agility. However, not all virtualization solutions are created equal. Performance, scalability, security, and cost can vary significantly between competing solutions. The degree of openness and standards-adherence also vari...

Data centers have become indispensable infrastructure for data storage and facilitating the development of diversified network services and applications offered by the cloud. Rapid development of these applications and services imposes various resource demands that results in increased energy consumption. This necessitates the development of efficient energy management techniques in data center...

Currently, the exchange cycles of various computers, smartphones, tablets, and others have become shorter, because new high-performance devices continue to roll out rapidly. However, existing legacy devices are not old-fashioned or obsolete to use. From the perspective of sustainable information technology (IT), energy-efficient virtualization can apply a way to increase reusability for special...
