Cloud providers need tomanage complex infrastructures in a seamless fashion to support the highly dynamic andheterogeneous workloads and hosted applications customers deploy. Similarly, HPCenvironments have been increasingly adopting techniques that enable flexible managementof vast computing and networking resources, close to marginal provisioning cost, which isunprecedented in the history of scientific and commercial computing.Various virtualization technologies contribute to the overall picture in different ways: machinevirtualization, with its capability to enable consolidation of multiple underutilized servers withheterogeneous software and operating systems (OSes), and its capability to live-migrate afully operating virtual machine (VM) with a very short downtime, enables novel and dynamicways to manage physical servers; OS-level virtualization (i.e., containerization), with itscapability to isolate multiple user-space environments and to allow for their coexistencewithin 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 theunderlying physical topology is furthermore enabling virtualization of HPC infrastructures. PublicationAccepted papers will be published in a Springer LNCS proceedings volume.Topics of InterestThe VHPC program committee solicits original, high-quality submissions related tovirtualization across the entire software stack with a special focus on the intersection of HPCand the cloud.Major Topics- Virtualization in supercomputing environments, HPC clusters, HPC in the cloud and grids- OS-level virtualization and containers (LXC, Docker, rkt, Singularity, Shifter, i.a.)- Lightweight/specialized operating systems in conjunction with virtual machines- Novel unikernels and use cases for virtualized HPC environments- Performance improvements for or driven by unikernels- Tool support for unikernels: configuration/build environments, debuggers, profilers- Hypervisor extensions to mitigate side-channel attacks ([micro-]architectural timing attacks, privilege escalation)- VM & Container trust and security- Containers inside VMs with hypervisor isolation- GPU virtualization operationalization- Approaches to GPGPU virtualization including API remoting and hypervisor abstraction- Optimizations of virtual machine monitor platforms and hypervisors- Hypervisor support for heterogeneous resources (GPUs, co-processors, FPGAs, etc.)- Virtualization support for emerging memory technologies- Virtualization in enterprise HPC and microvisors- Software defined networks and network virtualization- Management, deployment of virtualized environments and orchestration (Kubernetes i.a.)- Workflow-pipeline container-based composability - Checkpointing facilitation utilizing containers and VMs - Emerging topics including multi-kernel approaches and NUMA in hypervisors- Operating MPI in containers/VMs and Unikernels - Virtualization in data intensive computing (big data) - HPC convergence- Adaptation of HPC technologies in the cloud (high performance networks, RDMA, etc.)- Performance measurement, modelling and monitoring of virtualized/cloud workloads- Latency-and jitter sensitive workloads in virtualized/containerized environments- I/O virtualization (including applications, SR-IOV, i.a.) - Hybrid local facility + cloud compute and based storage systems, cloudbursting- FPGA and many-core accelerator virtualization- Job scheduling/control/policy and container placement in virtualized environments- Cloud reliability, fault-tolerance and high-availability- QoS and SLA in virtualized environments- IaaS platforms, cloud frameworks and APIs- Energy-efficient and power-aware virtualization- Configuration management tools for containers (including in OpenStack, Ansible, i.a.)- ARM-based hypervisors, ARM virtualization extensionsSpecial Track: GPU - Accelerator VirtualizationGPU virtualization technologies, performance and benchmarking, integration withworkflow scheduling systems, integration to cluster managers.GPUs are taking on many HPC workload areas, especially in deep learning withinmachine 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 managerlevel (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 levelDevelopers - Real-life experience when addressing HPC/ML/DL problems with GPUs or hardware accelerators in virtual environmentsPerformance - Performance comparisons between different technologies / solutionsThe Workshop on Virtualization in High-Performance Cloud Computing (VHPC) aims tobring together researchers and industrial practitioners facing the challenges posed by virtualization in order to foster discussion, collaboration, mutual exchangeof knowledge and experience, enabling research to ultimately provide novelsolutions for virtualized computing systems of tomorrow.The workshop will be one day in length, composed of 20 min paper presentations, eachfollowed by 10 min discussion sections, plus lightning talks that are limited to 5 minutes.Presentations may be accompanied by interactive demonstrations.Important DatesFebruary 23, 2018 (AoE) - Abstract SubmissionApril 23, 2018 (AoE) - Paper submission deadline (Springer LNCS)May 30, 2018 - Acceptance notification June 28, 2018 - Workshop DayJuly 12, 2018 - Camera-ready version dueChairMichael Alexander (chair), Institute of Science and Technology, AustriaAnastassios Nanos (co-chair), OnApp, UKRomeo Kienzler (co-chair), IBM, SwitzerlandProgram committeeStergios Anastasiadis, University of Ioannina, Greece Jakob Blomer, CERN, Europe Eduardo César, Universidad Autonoma de Barcelona, SpainStephen Crago, USC ISI, USATommaso Cucinotta, St. Anna School of Advanced Studies, ItalyChristoffer Dall, Columbia University, USAFrançois Diakhaté, CEA, FrancePatrick Dreher, MIT, USA Kyle Hale, Northwestern University, USA Brian Kocoloski, University of Pittsburgh, USAUday Kurkure, VMware, USAJohn Lange, University of Pittsburgh, USAGiuseppe Lettieri, University of Pisa, ItalyQing Liu, Oak Ridge National Laboratory, USANikos Parlavantzas, IRISA, FranceKevin Pedretti, Sandia National Laboratories, USAAmer Qouneh, Western New England University, USA Carlos Reaño, Technical University of Valencia, SpainBorja Sotomayor, University of Chicago, USA Anata Tiwari, San Diego Supercomputer Center, USAKurt Tutschku, Blekinge Institute of Technology, Sweden Yasuhiro Watashiba, Osaka University, JapanChao-Tung Yang, Tunghai University, Taiwan Andrew Younge, Sandia National Laboratory, USANa Zhang, VMware, USAPaper Submission-PublicationPapers submitted to the workshop will be reviewed by at least twomembers of the program committee and external reviewers.
