-The Cloud computing offers dynamically scalable resources provisioned as a service over the Internet. It enables individuals and organization to use various services like software as a service (SaaS), Platform as a Service (PaaS) and Infrastructure as a Service(IaaS) over the Internet. Virtualization is the fundamental technology that powers cloud computing. Virtualization allows running multi...

At present, the mostly used and developed mechanism is hardware virtualization which provides a common platform to run multiple operating systems and applications in independent partitions. More precisely, it is all about resource virtualization as the term ‘hardware virtualization’ is emphasized. In this paper, the aim is to find out the advantages and limitations of current virtualization tec...

We introduce a virtualization technology into the control system as operator consoles. The virtualization technology is a hot topic for server computing. The virtualization technology enables to consolidate a lot of server computers to a few host computers and reduces system maintenance cost drastically. Recently a dozen of commercial and non-commercial virtualization products are proposed. We ...

Wireless testbed virtualization aims to provide a stable, reproducible, environment that is capable of simultaneously supporting multiple radio experiments in the same RF environment. Our study provides a brief overview of current effort in the direction of virtualization, and aspects affecting the feasibility of such setups. Our preliminary studies involve comparison of current virtualization ...

The importance of heterogeneous multicore programming is increasing, and Open Computing Language (OpenCL) is an open industrial standard for parallel programming that provides a uniform programming model for programmers to write efficient, portable code for heterogeneous computing devices. However, OpenCL is not supported in the system virtualization environments that are often used to improve ...

For the majority of common workloads, performance in a virtualized environment is close to that in a native environment. Virtualization does create some overheads, however. These come from the virtualization of the CPU, the MMU (Memory Management Unit), and the I/O devices. In some of their recent x86 processors AMD and Intel have begun to provide hardware extensions to help bridge this perform...

Embedded virtualization paired with multi-core CPUs is paving the way for the consolidation of multiple dissimilar workloads within a single embedded device. Products such as those found in industrial automation, medical imaging, and networking or telecom applications are enjoying the benefits of increased compute capacity and decreased power consumption offered by multi-core CPUs. A challenge ...

It has been widely accepted that software virtualization has a big negative impact on high-performance computing (HPC) applications performance. This work explores the potential use of Infiniband hardware virtualization in an OpenNebula cloud towards the efficient support of MPI-based workloads. We have implemented, deployed, and tested an Infiniband network on the FermiCloud private IaaS cloud...

We consolidated more than 50 operator consoles of SPring-8 beamlines into four server computers by using virtualization technology. Virtualization technology has been a hot topic in server computing in recent years. We evaluated and studied several virtualization products for several years. To test feasibility of virtualization technology, we installed Xen into the control systems of a few beam...

Virtualization is generally adopted in server and desktop environments to provide for fault tolerance, resource management, and energy efficiency. Virtualization enables parallel execution of multiple operating systems (OSs) while sharing the hardware resources. Virtualization was previously not deemed as feasible technology for mobile and embedded devices due to their limited processing and me...
