In this paper we tackle the problem of providing Quality of Service guarantees to virtualized
applications, focusing on computing and networking guarantees. We propose a mechanism …

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 …

Tightly-coupled parallel applications in cloud systems may suffer from significant
performance degradation because of the resource over-commitment issue. In this paper, we …

The move towards high-performance computing (HPC) applications comprised of coupled
codes and the need to dramatically reduce data movement is leading to a reexamination of …

High performance parallel computing demands careful synchronization, timing, performance
isolation and control, as well as the avoidance of OS and other types of noise. The …

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 …

Virtual machine based distributed computing greatly simplifies and enhances
adaptive/autonomic computing by lowering the level of abstraction, benefiting both resource …

Ubiquitous sensing in human spaces is rapidly becoming a fact of life. Large collections of
IoT devices feed a vast sensing infrastructure that records and analyzes personal and …

The optimization problems associated with adaptive and autonomic computing systems are
often difficult to pose well and solve efficiently. A key challenge is that for many applications …

This paper proposes a prediction engine designed for non-dedicated clusters, which is able
to estimate the turnaround time for parallel applications, even in the presence of serial …
