    Dr Tom Downes (University of Wisconsin-Milwaukee)
    30/01/2018, 15:00

    In this lightning talk, I will discuss the development of a webhook-based tool for automatically converting Docker images from DockerHub and private registries to CVMFS filesystems. The tool is highly reliant on previous work by the Open Science Grid for scripted nightly conversion of images from DockerHub.

    Miklos Szeredi (Red Hat)
    31/01/2018, 08:30

    OverlayFS is the "union filesystem" soltion that is now available as part of the Linux kernel. OverlayFS is currently in active development. POSIX compliance, NFS export and improved performance are currently being worked on. There are plans to add user namespace and unprivileged mounting support.

    FUSE is a userspace interface for developing filesystems. FUSE started out on Linux, but is...

  21. 15. Designing the Git Virtual File System (GVFS)
    Saeed Noursalehi (Microsoft)
    31/01/2018, 09:10

    We’ve built a virtual file system that enables the Windows team to work in a Git repository that is a few orders of magnitude larger than what Git was previously able to support. In this talk we’ll cover a high level overview of the scale challenges we faced with Git, how we designed our virtual file system on top of NTFS, and some of the difficulties we ran into while building a file system...

  22. 16. Building Reproducible Science with Singularity Containers
    Michael Bauer
    31/01/2018, 10:10

    One of the biggest problems in scientific HPC is ensuring that results are reproducible. That is, the code a scientist runs locally must be able to run identically on any computational resource. Until recently, the job of ensuring that fell to system administrators who needed to manage a complex web of tools and dependencies on those resources. However, with the introduction of HPC containers...

  23. 17. Tooling for Using Linux
    Justin Cormack (Docker)
    31/01/2018, 10:50

    LinuxKit is a framework for building small, modular, immutable Linux systems that was open sourced last year by Docker. It came via a different design process than CernVM but shares much of the same philosophy. This talk looks at similarities and differences, and shows how to construct systems with LinuxKit, and future developments. It will also cover containerd, the new container runtime that...

  27. 27. West-Life, Tools for Integrative Structural Biology
    Tomas Kulhanek (STFC Daresbury Laboratory)
    31/01/2018, 15:20

    Structural biology is part of molecular biology focusing on determining structure of macromolecules inside living cells and cell membranes. As macromolecules determines most of the functions of cells the structural knowledge is very useful for further research in metabolism, physiology to application in pharmacology etc.

    As macromolecules are too small to be observed directly by light...

    HEATH SKARLUPKA (University of Wisconsin Madison)
    31/01/2018, 16:30

    IceCube is a cubic kilometer neutrino detector located at the south pole. CVMFS is a key component to IceCube’s Distributed High Throughput Computing analytics workflow for sharing 500GB of software across datacenters worldwide. Building the IceCube software suite across multiple platforms and deploying it into CVMFS has until recently been a manual, time consuming task that doesn’t fit well...

  31. 26. cernatschool.org's use of CVMFS and the CernVM
    Will Furnell
    31/01/2018, 16:45

    cernatschool.org is a very small Virtual Organisation made up of secondary school and university students, and participating organisations in the Institute for Research in Schools.

    We use CVMFS to delpoy dependencies and Python 3 itself for custom software used for analysing radiation data from Medipix detectors. This software is designed for running on GridPP worker nodes, part of the UK...
