9th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '14)

held in conjunction with Euro-Par 2014, August 25-29, Porto, Portugal

Paper Submission Deadline: May 30, 2014


Virtualization technologies constitute a key enabling factor for
flexible resource
management in modern data centers, and particularly in cloud environments. Cloud
providers need to dynamically manage complex infrastructures in a
seamless fashion for
varying workloads and hosted applications, independently of the
customers deploying
software or users submitting highly dynamic and heterogeneous
workloads. Thanks to
virtualization, we have the ability to manage vast computing and
networking resources
dynamically and close to the marginal cost of providing the services, which is
unprecedented in the history of scientific and commercial computing.
Various virtualization technologies contribute to the overall picture
in different ways: machine
virtualization, with its capability to enable consolidation of
multiple under-utilized
servers with heterogeneous software and operating systems (OSes), and
its capability to
live-migrate a fully operating virtual machine (VM) with a very short
downtime, enables
novel and dynamic ways to manage physical servers; OS-level
virtualization, with its
capability to isolate multiple user-space environments and to allow
for their co-existence
within the same OS kernel, promises to provide many of the advantages of machine
virtualization with high levels of responsiveness and performance; I/O
allows physical NICs/HBAs to take traffic from multiple VMs; network
with its capability to create logical network overlays that are
independent of the underlying
physical topology and IP addressing, provides the fundamental ground
on top of which
evolved network services can be realized with an unprecedented level
of dynamicity and
flexibility; the increasingly adopted paradigm of Software-Defined
Networking (SDN)
promises to extend this flexibility to the control and data planes of
network paths.
These technologies have to be inter-mixed and integrated in an
intelligent way, to support
workloads that are increasingly demanding in terms of absolute performance,
responsiveness and interactivity, and have to respect well-specified
Agreements (SLAs), as needed for industrial-grade provided services.
Indeed, among
emerging and increasingly interesting application domains for
virtualization, we can find
big-data application workloads in cloud infrastructures, interactive
and real-time multimedia
services in the cloud, including real-time big-data streaming
platforms such as used in
real-time analytics supporting nowadays a plethora of application
domains. Distributed
cloud infrastructures promise to offer unprecedented responsiveness
levels for hosted
applications, but that is only possible if the underlying
virtualization technologies can
overcome most of the latency impairments typical of current
virtualized infrastructures (e.g.,
far worse tail-latency). What is more, in data communications Network Function
Virtualization (NFV) is becoming a key technology enabling a shift
from supplying
hardware-based network functions, to providing them in a
software-based and elastic way.
In conjunction with (public and private) cloud technologies, NFV may be used for
constructing the foundation for cost-effective network functions that
can easily and
seamlessly adapt to demand, still keeping their major carrier-grade
characteristics in terms
of QoS and reliability.

The Workshop on Virtualization in High-Performance Cloud Computing
(VHPC) aims to
bring together researchers and industrial practitioners facing the
challenges posed by
virtualization in order to foster discussion, collaboration, mutual
exchange of knowledge
and experience, enabling research to ultimately provide novel
solutions for virtualized
computing systems of tomorrow.

The workshop will be one day in length, composed of 20 min paper
presentations, each
followed by 10 min discussion sections, and lightning talks, limited
to 5 minutes.
Presentations may be accompanied by interactive demonstrations.
