Scaling ML models on Google's TPUs

Tensor Processing Units are Machine Learning accelerators developed at Google. A TPU v3 Pod offers over 100 PFLOPs of compute, leading to dramatic reductions in training time of Machine Learning models. In this talk, we will explore some of the scalability challenges, often not unique to TPUs, and techniques to address those challenges. Naveen Kumar is a Software Engineer at Google. He currently leads Performance within Google Brain. Previously, Naveen worked on Google's second generation Tensor Processing Units. Prior to Google, Naveen focused on microprocessor research at Intel Labs. Naveen holds a PhD from University of Pittsburgh and enjoys outdoor life in the Bay Area.

Scaling Deep Learning Workloads on GPUs

The computational size, complexity and footprint of neural network training has been doubling about every 3.5 months, according to OpenAI. As well, the amount of data used for training has been increasing, for instance as researchers are able to take advantage of unsupervised training methods as in BERT. These researchers now require multiple systems for training their models (a trend similar to scientific simulations on HPC systems in the past). This talk will discuss the techniques needed for running deep learning training at scale on GPUs, and state of the art results. The discussion will also review how to deploy, scale, load balance and optimize the trained network inference (or prediction) throughput on GPUs, using tools such as TensorRT Inference Server. Ujval has spent the last 10 years working on software and libraries for deep learning and HPC at NVIDIA. Previously, he co-founded Stream Processors, a fabless-semi startup building programmable processors for signal and image processing. Ujval earned his PhD in EE at Stanford and a BS at Brown University.

We will cover a wide range of performance experiments, including good ideas that failed, and summarize the lessons we learned along the way. Sarvesh leads the performance team at Bing, Microsoft and is passionate about solving complex data problems with rich visualizations. Sarvesh holds a M.S. in Computer Science from Columbia University, NY.
1:55pm - 2:25pm

Open-Source Browser Contributions at Facebook

The Web as an application platform is still very much behind native platforms like Android and Windows for performance and richness of integration APIs. This makes it challenging for developers to create sophisticated yet performant webapps which require a non-trivial amount of client-side JS code. The Browser Engineering team at Facebook finds bottlenecks in browser implementations, contributes code to open-source browsers, prototypes new Web technologies, and advances new API proposals through Web standards committees. This talk will cover our current and future projects for making Web apps as fast and as powerful as native apps, including the new isInputPending() API, the upcoming JS Self-Profiling API, and new ideas for eliminating JavaScript overheads. Vladan is the tech lead for the Browser Engineering team at Facebook. His technical focus is browser technology, performance, and low-level systems. Previously, he lead the Firefox performance team at Mozilla, working on browser startup, responsiveness and performance measurement.
2:25pm - 3:00pm

FlameScope: A Different Way of Looking at Profilers

Even under constant load, the behavior of a system is affected by variance, perturbations, single-threaded execution and other time-based issues, and never completely uniform. Using profilers to analyze the performance of a system generally involves aggregating events or samples over a period of time, and identifying these small variations in the full profile becomes a needle-in-a-haystack problem. FlameScope solves this by combining a subsecond-offset heatmap, for navigating a profile and visualizing these perturbation, with a flame graphs for code-path analysis. For the past 13 years Martin's career evolved around technology and performance engineering, leading major initiatives at Netflix, Expedia and other companies. Currently, as a Performance Architect at Netflix, Martin is responsible for improving the performance of the Netflix service, for its 148+ million users, watching hundreds of millions of hours of movies and TV shows every day. Martin is also a Venture Advisor at monashees+, one of the largest venture capital firms in Brazil, angel investor and advisor to multiple startups, and an avid open source contributor.

Improving iOS Startup Performance with Binary Layout Optimizations

Startup of the iOS app is an important performance metric user experience. However, poor ordering of functions in the iOS binary can greatly increase page faults during startup and significantly hurt startup performance. An “order file” can be used to direct the linker how to order functions in an iOS binary better. To generate an order file for iOS apps, we usually use dtrace, but some apps have multiple startup scenarios that we want to optimize for with the order file. The dtrace approach does not scale well and it is not easy to automate. In this talk, we describe some more scalable approaches to generating order files. Manman Ren is a Software Engineer at Facebook. She currently works on iOS app performance. Previously, Manman worked at Apple's compiler team and on bringing Android to support IA at Intel. Manman holds a PhD from Stanford University.
