VHPC 2025

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 HPC/Cloud scenarios in order to foster discussion, collaboration, mutual exchange of knowledge and experience, enabling research to ultimately provide novel solutions for virtualized computing systems.

The workshop features paper presentations, discussion sessions, and lightning talks. Accepted papers will be published in a Springer LNCS volume.

Focus Topics

• GPU hypervisor memory virtualization: Techniques for virtualizing GPU memory to allow flexible and efficient allocation across multiple workloads
• Flat CPU/GPU memory page tables/TLB: Unified virtual memory spaces and page table structures
• Storage/filesystem to virtual memory mapped approaches
• Distributed memory virtualization
• Memory compression and reduction techniques: Approaches for compressing model parameters, activations, and gradients
• Out-of-core training algorithms
• Efficient memory allocation and management
• Memory-efficient data formats and processing
• Benchmarking and profiling tools
• Case studies and applications in LLM training scenarios

In addition to regular topics:

• Container Platforms (Kubernetes, Docker/Podman, Nitro/Firecracker, Singularity, …) and Unikernel Frameworks
• Composable Lightweight Application Components and Lambda / Function-as-a-Service Paradigms
• Latency Control, Warm/Cold-start issues and Data/Container Placement
• Energy-efficiency and Service Orchestration in Virtualized Cloud & HPC Infrastructures

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 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 enables consolidation and live-migration capabilities; OS-level virtualization (containerization) promises many advantages with high performance; unikernels provide virtualization benefits with minimized OS/library surface. I/O virtualization, network virtualization, and storage virtualization continue to evolve to support increasingly demanding requirements.

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.

Paper Submission & Publication

Papers submitted to the workshop will be reviewed by at least two members of the program committee and external reviewers. Submissions should include abstract, keywords, the e-mail address of the corresponding author, and must not exceed 10 pages, including tables and figures at a main font size no smaller than 11 points.

Accepted papers will be published in a Springer LNCS volume (SCOPUS indexed). The format must be according to the Springer LNCS Style. Camera-ready versions are allowed a maximum of 12 pages.

Lightning Talks

Lightning Talks are in a non-paper track, synoptical in nature and strictly limited to 5 minutes. They can be used to gain early feedback on ongoing research, for demonstrations, to present research results, early research ideas, perspectives and positions of interest to the community. Submit abstracts via the main submission link.
