Abstract

Virtualization technologies constitute a key enabling factor for flexible resource management in modern data centers, cloud environments, and increasingly in HPC as well. 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 Virtualization allows physical network adapters to take traffic from multiple VMs; network virtualization, 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; 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 Service– Level 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). 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. TOPICS Topics of interest include, but are not limited to: – Virtualization in supercomputing environments, HPC clusters, cloud HPC and grids – Optimizations of virtual machine monitor platforms, hypervisors and OS–level virtualization – Hypervisor and network virtualization QoS and SLAs – Cloud based network and system management for SDN and NFV – Management, deployment and monitoring of virtualized environments – Performance measurement, modelling and monitoring of virtualized/cloud workloads – Programming models for virtualized environments – Cloud reliability, fault–tolerance, high–availability and security – Heterogeneous virtualized environments, virtualized accelerators, GPUs and co–processors – Optimized communication libraries/protocols in the cloud and for HPC in the cloud – Topology management and optimization for distributed virtualized applications – Cluster provisioning in the cloud and cloud bursting – Adaptation of emerging HPC technologies (high performance networks, RDMA, etc..) – I/O and storage virtualization, virtualization aware file systems – Job scheduling/control/policy in virtualized environments – Checkpointing and migration of VM–based large compute jobs – Cloud frameworks and APIs – Energy–efficient / power–aware virtualization
