  1. 2. Exploring Cloudflare Workers
    Harris Hancock (Cloudflare)
    04/06/2019, 09:00

    Cloudflare Workers is a serverless computing platform optimized to minimize latency to end users. Cloudflare runs every guest function in each server of its network's 175 points of presence, meaning code runs as close to the end user as possible, and is not confined to geographic regions. This requires overcoming a scalability challenge faced by container-based platforms: how to reduce each...

  2. 3. The evolution of the HPC facility at JSC
    Dorian Krause (Jülich Supercomputing Centre)
    04/06/2019, 09:45

    The Jülich Supercomputing Centre (JSC) operates a large-scale network-, data- and compute-infrastructure for scientific research covering a broad spectrum of use cases from scalability-focused large-scale simulations to community-specific services with high-throughput requirements. In this talk we will discuss the design of JSC’s facility addressing such different use cases though a mixture of...

  3. 19. Solving Problems in HPC with Singularity
    Michael Bauer (Sylabs)
    04/06/2019, 11:00

    The Singularity container runtime has become widely adopted as the de facto standard container platform for HPC workloads. At the beginning of 2018, Sylabs was founded to further HPC innovation by driving Singularity development. This talk will explore some of the ways in which the Singularity community and Sylabs are helping to solve problems in the HPC space, with a focus on the efforts of...

  6. 22. Rootless containers with Podman and fuse-overlayfs
    Giuseppe Scrivano (Red Hat)
    04/06/2019, 17:00

    During my talk, I will show how it is possible to run OCI containers with Podman without requiring root privileges on the host.

    In the second part of the talk, I'll focus on how we use fuse-overlayfs to replace the kernel overlay file system implementation, and the fuse-overlayfs built-in shifts-like capabilities.
