14. Evolution of FUSE and OverlayFS

Miklos Szeredi (Red Hat)

1/31/18, 8:30 AM

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...

15. Designing the Git Virtual File System (GVFS)

Saeed Noursalehi (Microsoft)

1/31/18, 9:10 AM

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...

16. Building Reproducible Science with Singularity Containers

Michael Bauer

1/31/18, 10:10 AM

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...

17. Tooling for Using Linux

Justin Cormack (Docker)

1/31/18, 10:50 AM

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...
