A Virtualization Architecture for In-depth Kernel Isolation ∗

by Jiang Wang, Sameer Niphadkar, Angelos Stavrou, Anup K. Ghosh
"... Recent advances in virtualization technologies have sparked a renewed interest in the use of kernel and process virtualization as a security mechanism to enforce resource isolation and management. Unfortunately, virtualization solutions incur performance overhead. The magnitude of this overhead is d ..."

is directly proportional to the extend of virtualization they offer: full virtualization incurs an additional indirection layer to interface with the ever increasing hardware devices. In this paper, we propose a hypervisor-assisted, microkernel architecture which aims to provide in-depth resource isolation

An Open Software Architecture for Virtual Reality Interaction

by Gerhard Reitmayr, Dieter Schmalstieg - In Proc. VRST'01 , 2001
"... This article describes OpenTracker, an open software architecture that provides a framework for the di#erent tasks involved in tracking input devices and processing multimodal input data in virtual environments and augmented reality application. The OpenTracker framework eases the development and ma ..."

and maintenance of hardware setups in a more flexible manner than what is typically o#ered by virtual reality development packages. This goal is achieved by using an object-oriented design based on XML, taking full advantage of this new technology by allowing to use standard XML tools for development

Performance Profiling in a Virtualized Environment

by Jiaqing Du, Nipun Sehrawat, Willy Zwaenepoel - Proc. HotCloud 2010
"... Virtualization is a key enabling technology for cloud computing. Many applications deployed in a cloud run in virtual machines. However, profilers based on CPU performance counters do not work well in a virtualized environment. In this paper, we explore the possibilities for achieving performance pr ..."

profiling in virtual machine monitors (VMMs) built on paravirtualization, hardware assistance, and binary translation. We present the design and implementation of performance profiling for a VMM based on the x86 hardware extensions, with some preliminary experimental results. 1

A full GPU virtualization solution with mediated pass-through.

by Kun Tian , Yaozu Dong , David Cowperthwaite - In Proc. USENIX ATC, , 2014
"... Abstract Graphics Processing Unit (GPU) virtualization is an enabling technology in emerging virtualization scenarios. Unfortunately, existing GPU virtualization approaches are still suboptimal in performance and full feature support. This paper introduces gVirt, a product level GPU virtualization ..."

garnered significant research attention, fostering a race to achieve the lowest possible virtualization overhead. The evolution has led to three primary virtualization approaches: full-virtualization, para-virtualization, and container-based virtualization, each with a unique set of strengths

Virtual Distributed Environments in a Shared Infrastructure

by Xuxian Jiang, Dongyan Xu - IEEE Computer , 2005
"... A middleware system that integrates and elevates virtual machine and virtual network technologies facilitates the creation of virtual distributed environments in a shared infrastructure. Spanning multiple domains, the Grid provides for the federation, allocation, and management of heterogeneous netw ..."

Full Length Research Paper Effective virtual teams for new product development

by Nader Ale Ebrahim, Shamsuddin Ahmed, Salwa Hanim, Abdul Rashid, Zahari Taha , 2012
"... At present, the existing literature shows that the factors which influence the effectiveness of virtual teams for new product development are still ambiguous. To address this problem, a research design was developed, which includes detailed literature review, preliminary model and field survey. From ..."
Abstract - Add to MetaCart
. From literature review, the factors which influence the effectiveness of virtual teams are identified and these factors are modified using a field survey. The relationship between knowledge workers (people), process and technology in virtual teams is explored in this study. The results of the study

A Database of Full Body Virtual Interactions Annotated with Expressivity Scores

by V Demulier , E Bevacqua , F Focone , T Giraud , P Carreno , S Gibet , P De Loor , J-C Martin
"... Abstract Recent technologies enable the exploitation of full body expressions in applications such as interactive arts but are still limited in terms of dyadic subtle interaction patterns. Our project aims at full body expressive interactions between a user and an autonomous virtual agent. The curr ..."
