XPDDS17: PVH Dom0: The Road so Far - Roger Pau Monné, CitrixThe Linux Foundation
This talk will start with an overview of the x86 PVH Dom0 architecture together with some basic information about it, in order for the audience to understand why does Xen need PVH, and even more, why does Xen need a PVH Dom0 at all.
Then it will dive into the hypervisor side implementation, in order to understand how is PVH Dom0 implemented, and in which way it interacts with the existing Xen internal interfaces and subsystems. Details about the current implementation status will also be provided, together with a roadmap of the missing bits.
Hopefully after the talk the audience should have a good understanding about what's this new PVH mode, and how is it implemented inside of Xen.

OSv Unikernel — Optimizing Guest OS to Run Stateless and Serverless Apps in t...ScyllaDB
Unikernels have been demonstrated to deliver excellent performance in terms of throughput and latency, while providing high isolation. However they have also been shown to underperform in some types of workloads when compared to a generic OS like Linux. In this presentation, we demonstrate that certain types of workloads - web servers, microservices, and other stateless and/or serverless apps - can greatly benefit from OSv optimized networking stack and other features. We describe number of experiments where OSv outperforms Linux guest: most notably we note 1.6 throughput (req/s) and 0.6 latency improvement (at p99 percentile) when running nginx and 1.7 throughput (req/s) and 0.6 latency improvement (at p99 percentile) when running simple microservice implemented in Golang.
We also show that OSv' small kernel, low boot time and memory consumption allow for very high density when running server-less workloads. The experiment described in this presentation shows we can boot 1,800 OSv microVMs per second on AWS c5n.metal machine with 72 CPUs (25 boots/sec on single CPU) with guest boot time recorded as low as 8.98ms at p50 and 31.49ms at p99 percentile respectively.
Lastly we also demonstrate how to automate the build process of the OSv kernel tailored exactly to the specific app and/or VMM so that only the code and symbols needed are part of the kernel and nothing more. OSv is an open source project and can be found at https://github.com/cloudius-systems/osv.
This presentation gives a summary of SDXCentral 2017 Report on NFV Industry and its trends. The presentation gives jump start for beginners to navigate through NFV forest by getting necessary details and expand understanding elaborating each piece of puzzle.
It is the presentation file used by Jim Huang (jserv) at OSDC.tw 2009. New compiler technologies are invisible but highly integrated around our world, and we can enrich the experience via facilitating LLVM.
Presentation at Android Builders Summit 2012.
Based on the experience of working with ODM companies and SoC vendors, this session would discuss how to figure out the performance hotspot of certain Android devices and then improve in various areas including graphics and boot time. This session consists of the detailed components which seem to be independent from each other in traditional view. However, the situation changes a lot in Android system view since everything is coupled in a mass. Three frequently mentioned items in Android engineering are selected as the entry points: 2D/3D graphics, runtime, and boot time. Audience: Developers who work on Android system integration and platform enablement.

Two years ago, Spotify introduced Scio, an open-source Scala framework to develop data pipelines and deploy them on Google Dataflow. In this talk, we will discuss the evolution of Scio, and share the highlights of running Scio in production for two years. We will showcase several interesting data processing workflows ran at Spotify, what we learned from running them in production, and how we leveraged that knowledge to make Scio faster, and safer and easier to use.
