CfP 13th Virtualization in High-Performance Cloud Computing Workshop (VHPC '18) ==================================================================== CALL FOR PAPERS 13th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '18) held in conjunction with the International Supercomputing Conference - High Performance, June 24-28, 2018, Frankfurt, Germany. (Springer LNCS Proceedings) ==================================================================== Date: June 28, 2018 Workshop URL: http://vhpc.org Paper Submission Deadline: May 15, 2018 (extended). Springer LNCS, rolling abstract submission Abstract/Paper Submission Link: https://edas.info/newPaper.php?c=24355 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 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 (i.e., containerization), 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 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. Publication Accepted papers will be published in a Springer LNCS proceedings volume. Topics of Interest The VHPC program committee solicits original, high-quality submissions related to virtualization across the entire software stack with a special focus on the intersection of HPC and 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 extensions 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.
