A Virtual Machine Monitor for Providing a Single System Image
نویسندگان
چکیده
We have designed and implemented a virtual machine monitor that virtualizes a sharedmemory multi-processor machine on a commodity cluster. This functionality greatly simplifies utilization of commodity clusters. For example, it enables parallel applications for sharedmemory multi-processor systems to run on clusters without any change of the applications. Moreover, commodity operating systems that support multi-processors (e.g., Linux) can be installed in a virtual machine with a small amount of modification. We built a virtual 8-way multi-processor machine on eight physical machines. We ran parallel coarse-grain tasks on Linux installed in the virtual machine and measured the execution time. The experimental result demonstrates the feasibility of our approach.

متن کاملImplementing Java on Clusters
We have implemented a virtual machine (VM) for Java which executes on a cluster. Our cluster VM completely hides the cluster from the application, presenting a single system image (SSI) (i.e., the application sees a traditional virtual machine). At the same time it leverages the cluster to achieve improved performance for a range of applications. We show how the flexibility and constraints of t...
متن کاملFault Isolation and Quick Recovery in Isolation File Systems
Lanyue Lu presented isolation file systems, providing fault isolation and quick recovery within a single file system. Because file systems are important data access interfaces in many environments, high availability is critical; however, a single fault can trigger a large-scale impact for the whole file system, such as remounting as read-only and a system crash. Lanyue explained how a metadata ...

Wedesigned and implemented threemiddleware systems for efficient use of dynamically joining and leaving computing resources. Clusters of computers and computational grids, which have become increasingly important, are dynamic environments. Because of factors such as resource sharing and failure, the quality of resources available to an application changes constantly. For example, since non-dedi...
متن کاملAnalysis of the Intel Pentium's Ability to Support a Secure Virtual Machine Monitor
A virtual machine monitor (VMM) allows multiple operating systems to run concurrently on virtual machines (VMs) on a single hardware platform. Each VM can be treated as an independent operating system platform. A secure VMM would enforce an overarching security policy on its VMs. The potential benefits of a secure VMM for PCs include: a more secure environment, familiar COTS operating systems a...
