[Call for Paper - late-breaking] VHPC'24: June 7th submission deadline
by Remo Andreoli 22 May '24

22 May '24

==================================================================== CALL FOR PAPERS 19th Workshop on Virtualization in High-Performance Cloud Computing (VHPC '24) held in conjunction with the European Conference on Parallel and Distributed Computing Aug 26-30, 2024, Madrid, Spain. (Springer LNCS Proceedings) ==================================================================== Paper submission deadline: June 7th, 2024 AoE (extended) Date: August 26, 27, 2024 Workshop URL: vhpc dot org To submit an abstract or paper, please follow the link provided in the Call for Papers (CfP) announcement at the end of this message. 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. 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 co-existence 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 manyvirtualization benefits with a minimized OS/library surface. I/O virtualization, in turn, allows physical network interfaces to exchange traffic with multiple VMs or containers; network virtualization, with its capability to create logical network overlays independently from the underlying physical topology, is another fundamental enabling technology for Cloud/HPC infrastructures. Last, storage virtualization needs to evolve to support increasingly demanding requirements in terms of performance and reliability for the managed application data. 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, containers/ virtualization and cloud computing.

Use cases and applications for RT-cloud - Use of cloud computing principles to improve performance/safety/ security in existing real-time systems/use cases - Real-time cloud and edge applications -- Industrial use cases and requirements -- Experiments and experiences with RT-cloud -- Real-time / safety-critical applications as a cloud-based service -- Real-time extension to existing cloud-computing technologies -- Decomposition between the edge, fog, and cloud 2. Virtualization and cloud computing technologies/models for RT-cloud - Development Operations (DevOps) for RT-cloud - Deterministic hypervisors and cloud execution environments, including containers and WASM - Real-time Saas, Paas, Iaas, and XaaS (anything as a service model) - Execution and deployment models for RT-Cloud, including serverless computing - Microservices Architectures for real-time system - Modeling of network and cloud, execution stacks, and applications - Adaptive SLAs for RT-cloud 3. Resource management (including monitoring, scheduling) and orchestration for RT-cloud -- Predictable orchestration and cloud operation -- Tools and techniques for resource sharing and isolation -- End-to-end resource management and scheduling in edge-cloud continuum -- Co-scheduling of virtual network and compute resources -- Edge-cloud-IoT continuum and interaction/interfacing -- QoS mechanisms and isolation guarantees -- Autonomous monitoring systems 4. Safety and Security for RT-cloud - Assurance in RT-cloud, deterministic scaling, fail-over, migration, etc. - Trusted RT-Cloud/edge environment -- Considering security and privacy together with safety -------------------------------------------------------------------------------- IMPORTANT DATES Submission deadline: May 16, 2024 (AoE) Notification of Acceptance: June 6, 2024 RT-Cloud Workshop: July 9, 2024 ECRTS 2024: July 9-12, 2024 -------------------------------------------------------------------------------- SUBMISSION INSTRUCTIONS Manuscripts must present original work.

Paper submissions are due on April 19th. Accepted papers will be published on Springer LNCS series, and indexed by Scopus, among others. Workshop Overview 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 seamlessly manage complex infrastructures, to support the highly dynamic and heterogeneous workloads 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-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 exchange traffic with multiple VMs or containers; network virtualization, with its capability to create logical network overlays independently from the underlying physical topology, is another fundamental enabling technology for Cloud/HPC infrastructures. Last, storage virtualization needs to evolve to support increasingly demanding requirements in terms of performance and reliability for the managed application data. *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, containers-virtualization and cloud computing, focusing on the following major topics: * HPC on Containers and VMs; * Containerized applications with OS-level virtualization; * Lightweight applications with Unikernels; * HPC-as-a-Service. Each of these major topics encompasses design/architecture, management, performance management, modeling and configuration/tooling, leading to the following detailed, but non-necessarily exhaustive, list of topics of interest: Design / Architecture: * Containers and OS-level virtualization (LXC, Docker, rkt, Singularity, Shifter, i.a.) * Hypervisor support for heterogeneous resources (GPUs, co-processors, FPGAs, etc.) * Hypervisor extensions to mitigate side-channel attacks([micro-]architectural timing attacks, privilege escalation) * VM & Container trust and security models * Multi-environment coupling, system software supporting in-situ analysis with HPC simulation * Cloud reliability, fault-tolerance and high-availability * Cloud-based quantum compute services * Energy-efficient and power-aware virtualization * Containers inside VMs with hypervisor isolation * Virtualization support for emerging memory and storage technologies * Lightweight/specialized operating systems in conjunction with virtual machines * Hypervisor support for heterogeneous resources (GPUs, co-processors, FPGAs, etc.) * Unikernels and use cases for virtualized HPC environments * Formal definition and verification of hypervisors and virtualization system properties * ARM-based hypervisors, ARM virtualization extensions Management: * Container and VM management for HPC and cloud environments * HPC services integration, services to support HPC * Service and on-demand scheduling & resource management * Dedicated workload management with VMs or containers * Workflow coupling with VMs and containers * Unikernels and lightweight VM application management * Environments and tools for operating containerized environments (batch, orchestration) * Models for non-HPC workload provisioning on HPC resources Performance Measurements and Modeling: * Performance improvements for, or driven by, unikernels * Optimizations of virtual machine monitor platforms and hypervisors * Scalability analysis of VMs and/or containers at large scale * Performance measurement, modeling and monitoring of virtualized/cloud workloads * Virtualization in supercomputing environments, HPC clusters, HPC in the cloud * Energy-efficient deployment of high-performance, ultra-low latency and real-time workloads in cloud infrastructures * Modeling, control and isolation of end-to-end performance for parallel & distributed cloud/HPC applications Configuration / Tooling: * Tool support for unikernels: configuration/build environments, debuggers, profilers * Job scheduling/control/policy and container placement in virtualized environments * Measuring and controlling "OS/Virtualization noise" * Operating MPI in containers/VMs and Unikernels * GPU virtualization operationalization *Organization* 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.
