Call for Papers


Containers and virtualization technologies constitute key enabling
factors for flexible resource management in modern data centers, and
particularly in cloud environments. Cloud providers need to manage
complex infrastructures in a seamless fashion to support the highly
dynamic and heterogeneous workloads and hosted applications customers
deploy. Similarly, HPC environments have been increasingly adopting
techniques that enable flexible management of vast computing and
networking resources, close to marginal provisioning cost, which is
unprecedented in the history of scientific and commercial computing.
Most recently, Function as a Service (Faas) and Serverless computing,
utilizing lightweight VMs-containers widens the spectrum of
applications that can be deployed in a cloud environment, especially
in an HPC context. Here, HPC-provided services become accessible
to distributed workloads outside of large cluster environments.

Various virtualization-containerization technologies contribute to the
overall picture in different ways: machine virtualization, with its
capability to enable consolidation of multiple under­utilized 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 (i.e., containerization),
with its capability to isolate multiple user­-space environments and
to allow for their co­existence within the same OS kernel, promises to
provide many of the advantages of machine virtualization with high
levels of responsiveness and performance; lastly, unikernels provide
for many virtualization benefits with a minimized OS/library surface.
I/O Virtualization in turn allows physical network interfaces to take
traffic from multiple VMs or containers; network virtualization, with
its capability to create logical network overlays that are independent
of the underlying physical topology is furthermore enabling
virtualization of HPC infrastructures.


Publication


Accepted papers will be published in a Springer LNCS proceedings
volume.

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, plus
lightning talks that are limited to 5 minutes. Presentations may be
accompanied by interactive demonstrations.
