Special Track: GPU - Accelerator Virtualization 

Call for Papers

Virtualization technologies constitute a key enabling factor 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.

Various virtualization 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; I/O Virtualization 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. 


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

Special Track: GPU - Accelerator Virtualization
GPU virtualization technologies, performance and benchmarking, integration with
workflow scheduling systems, integration to cluster managers.

GPUs are taking on many HPC workload areas, especially in deep learning within
machine learning. In addition, a lot of workload is being pushed to elastic environments 
utilizing various virtualization technologies on different levels like hypervisors 
(e.g. VMWare, Xen, KVM), kernel (Docker, Kubernetes) or on the resource manager
level (YARN, Mesos). In this track we invite submissions addressing these problems. 

Suggested Themes and Topics:

Technology - What technologies and best practices exist for GPU - hardware accelerator 
virtualization and usage of hardware accelerators in virtual environments on the hypervisor, 
kernel or resource manager level

Developers - Real-life experience when addressing HPC/ML/DL problems with GPUs or 
hardware accelerators in virtual environments

Performance - Performance comparisons between different technologies / solutions

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.
