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...

Virtualizing the physical resources of a computing system to improve sharing and utilization has been done for decades. Virtualization had once been confined to specialized server and mainframe systems, but improvements in the performance of platforms based on Intel technology now allow those platforms to efficiently support virtualization. However, the IA-32 and Itanium processor architectures...

Virtualization has received much attention the past few years. However, it is anything but new, as one of the first implementations were done in the 1960s to create a multi user system by running multiple instances of a single user operating system. Virtualization mechanisms have evolved much since that time, and an ever increasing number of similar technologies have been collected under the vi...

Virtualization is increasingly being used as a component in designing secure cyber architectures. The proposed applications include strong isolation, monitoring, fault tolerance, execution replay, etc. However, there are various virtualization approaches which differ in their security implications, proper applications, overheads, requirements, and most importantly threat models. Firstly, virtua...

For the last two decades, virtualization processes have been considered developing phenomena in management studies, particularly within the context of the creation of interand intra-organizational networks, establishing strong relationships with customers and the appreciation of intangible assets in companies. The purpose of this paper is to define the concept of virtualization from a marketing...

Despite its current popularity, para-virtualization has an enormous cost. Its diversion from the platform architecture abandons many of the benefits that come with pure virtualization (the faithful emulation of the platform API): stable and well-defined platform interfaces, single binaries for kernel and device drivers (and thus lower testing, maintenance, and support cost), and vendor independ...

In common sense, virtualization technology is adopted to offer several isolated execution environments and make better use of computational resources in server environment. However, in embedded systems, the significance of virtualization does not come into the picture. The extensive utilization of mobile smart devices has led to a series of issues such as security, wasting of resources, and pow...

The need for flexible, low-overhead virtualization is evident on many fronts ranging from high-density cloud servers to mobile devices. During the past decade OS-level virtualization has emerged as a new, efficient approach for virtualization, with implementations in multiple different Unix-based systems. Despite its popularity, there has been no systematic study of OS-level virtualization from...
