Track: Modern Operating Systems

Location: Bayview AB

Day of week: Monday

Operating systems occupy a critical spot in the systems we build, but are often ignored as something that is just there, providing an interface. Recently though there has been a huge amount of innovation in the area of operating systems. Rather than being an esoteric field, it has opened up to new experiments and a wider community. Performance requirements have meant that architectural changes are necessary, leading to different designs, such as eBPF, a new in kernel programming language, and high-performance userspace device drivers. Unikernels question the monolithic architecture, building an application-centric operating environment. Emulation has become a realistic way of running existing code in new environments, with Microsoft supporting Linux on Windows as a leading example. New programming languages are being used, and there is an explosion of innovation. This track explores these changes that are taking place in this exciting field.

Track Host: Justin Cormack

gVisor: Building and Battle Testing a Userspace OS in Go

gVisor is a container runtime that implements the Linux kernel API in userspace using Go. This talk explains why on earth such a thing exists and covers three main areas of interest: First, architectural challenges associated with userspace kernels, such as traps, faults and memory management. Second, positive and negative experiences with Go as an implementation language -- it's not all about garbage collection. Finally, how to ensure API coverage and compatibility, along with production anecdotes whenever possible.

Adin Scannell, Software Engineer @Google

5:25pm - 6:15pm

Is It Time to Rewrite the Operating System in Rust?

Bryan Cantrill, Co-Creator DTrace, Co-Founder Fishworks Sun Microsystems, & Currently CTO @Joyent
