  11. 6. Lazy Container Image Distribution With eStargz And P2P Image Sharing on IPFS
    Kohei Tokunaga
    13/09/2022, 09:30

    Pulling images is known as one of the time-consuming steps during starting up containers. In this talk, Kohei will share the approach of speeding up container startup using eStargz image format and recent works around eStargz.

    eStargz allows container runtimes to start containers without waiting for the pull completion. This has been available on a variety of tools in the community,...

  12. 24. Harbor Registry at CERN: Status and Enhancements
    Ricardo Rocha (CERN)
    13/09/2022, 09:50

    CERN offers a centralized OCI registry at registry.cern.ch, based on the Harbor project and available to the whole community. In addition to the standard container registry functionality, Harbor adds support for any kind of OCI artifact (Helm Charts, ML Models, etc) as well as support for proxy caches to external registries, automated replication between multiple registry instances,...

  15. 20. Decarbonizing Scientific Computing
    Andrew Grimshaw (Lancium Compute)
    13/09/2022, 11:20

    Scientific computing uses a tremendous amount of energy, and given the location of most HPC centers, results in a similarly large amount of CO2 emissions. In the US, for example, in 2019, every MWh of generated power on average led to 0.7 metric tons of CO2 emissions. To address the huge carbon footprint of computing Lancium Compute is building, low carbon, renewable-energy-driven data centers...

    Kenneth Hoste
    13/09/2022, 14:00

    The European Environment for Scientific Software Installations (EESSI, pronounced as "easy") is a collaboration between different HPC sites and industry partners, with the common goal to set up a shared repository of scientific software installations that can be used on a variety of systems, regardless of which flavor/version of Linux distribution or processor architecture is used, or whether...

  22. 23. ATLAS Cloud R&D, Kubernetes and CVMFS
    Fernando Harald Barreiro Megino (University of Texas at Arlington)
    13/09/2022, 16:00

    Different groups, sites and experiments in the WLCG community have started using Kubernetes to manage services, implement novel analysis facilities or run batch services . Despite being in a native containerised environment, many of these use cases depend on CVMFS to stay compatible with the existing Grid model or to benefit from a well established software distribution model. Multiple of...

  23. 27. A new UK StashCache at Edinburgh for DUNE
    Wenlong Yuan (Edinburgh University)
    13/09/2022, 16:20
    Presentation

    The Deep Underground Neutrino Experiment (DUNE) utilizes CVMFS and CVMFS StashCache to distribute both its software stack and reference files for distributed computing workflows. DUNE utilizes CVMFS as it provides a read-only POSIX interface to StashCache, with the redundant features, e.g. built-in GeoIP locating, rate monitoring, and fallback in failures. During Dec-’21 to Jan-’22, it was...
