[apologies for cross-postings] ==================================================================== 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 26th, 2024, Madrid, Spain. ==================================================================== Late-breaking submission deadline: June 7th, 2024 AoE (extended) (Springer LNCS Proceedings) Date: August 26th, 2024 Workshop URL: https://vhpc.github.io/ 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, uni-kernels 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. 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.
