>  Title:  Virtuoso: Distributed Computing Using Virtual Machines
>
>
> Abstract:
> Virtual machine monitors, such as VMware, Virtual PC, UML, VM, and 
> many others, provide a powerful mechanism that can be used to greatly 
> simplify wide-area distributed computing. These tools allow us to 
> lower the level of abtraction that resource providers can present to 
> their users to the advantage of both. The Virtuoso abstraction is that 
> of a raw machine with no software. The user can customize the hardware 
> of his virtual machine(s) (VMs), install whatever operating system and 
> software he needs, and instantiate and migrate his VMs to run on 
> whatever resources are most appropriate at any given time. The system 
> continuously executes measurement, inference, adaptation and resource 
> reservation techniques on behalf of the user’s VMs.
>  
>
> The Virtouso project is developing and extending the middleware 
> services necessary to make this vision of distributed computing 
> possible. Beyond introducing Virtuoso in general, this talk will 
> concentrate on the following specific topics:
>  
>
> • Virtual networking We have developed software that overlays an 
> adaptive protocol-agnostic layer 2 virtual network that connects the 
> user’s virtual machines, making them appear to be on his local 
> network.
> • Measurement and inference The virtual network provides an excellent 
> vantage point to discover the communications demands of a user’s VMs. 
> From the vantage point of the virtual network system, we can derive 
> the traffic load matrix and communication topology. We are now working 
> to measure the communication capabilities of the underlying network 
> using our transfers.
> • User-centric resource control Providers need to be able to control 
> resource contention among virtual machines to preserve the illusion of 
> separate machines to users. This is particularly important for 
> interactive VMs. We have studied user comfort with different kinds and 
> levels of resource contention and are now developing resource control 
> techniques that use direct user feedback.

> Biography
> Peter A. Dinda is an assistant professor in the Department of Computer 
> Science at Northwestern University. He holds a B.S. in electrical and 
> computer engineering from the University of Wisconsin and a Ph.D. in 
> computer science from Carnegie Mellon University. His research centers 
> on the intersection of interactive applications and high performance 
> computing, and in particular on frameworks, resource discovery, and 
> online performance analysis and prediction for such applications. He 
> is the recipient of a 2001 NSF CAREER award, and holds the Slivka 
> junior chair of computer science at Northwestern.
