Virtualization can deliver significant benefits for cloud computing by enabling VM migration
to improve utilization, balance load and alleviate hotspots. While several mechanisms exist …

Distributed system emulators provide a paramount platform for testing of network protocols
and distributed applications in clusters and networks of workstations. However, to allow …

Experimental computer systems research typically ignores the end-user, modeling him, if at
all, in overly simple ways. We argue that this (1) results in inadequate performance …

Distributed systems, such as grids, are composed of geographically distributed computing
elements that belong to multiple administrative domains and are controlled by multiple …

It is now possible to allow VMs hosting HPC applications to seamlessly bridge distributed
cloud resources and tightly-coupled supercomputing and cluster resources. However, to …

We propose a new approach to scheduling virtual machines (VMs) on a provider CPU that is
unique in that is based around the use of direct user input. In our system, a user's VM is …

An execution environment consisting of virtual machines (VMs) interconnected with a virtual
overlay network can use the naturally occurring traffic of an existing, unmodified application …

In a resource-constrained, contested environment, computing resources need to be aware of
possible size, weight, and power (SWaP) restrictions. SWaP-aware computational efficiency …

A collection of virtual machines (VMs) interconnected with an overlay network with a layer 2
abstraction has proven to be a powerful, unifying abstraction for adaptive distributed and …

In the last decade we have seen tremendous increases in computer and network speeds
and performance, resulting in the emergence of wide-area distributed computing. However …
