  CS Colloquium - Jonathan Balkind - "Fixing Serverless Computing in the Post-Moore Era With Open-Source Hardware"

  Department of Computer Science

  12:00 PM Room 3514, Mudd Hall ( formerly Seeley G. Mudd Library)

  EVENT DETAILS

  Title: Knowledge Is Power: Sensing The Physical World Around Devices

  Abstract

  Function-as-a-Service "serverless" platforms like Amazon Lambda have quickly emerged as a popular environment for developers since their arrival in 2014. FaaS offers developers automatic scaling of their applications with user demand and the promise to only pay for the resources their application uses, down to the millisecond range. Despite its desirability and positive features, FaaS has its dirty secrets. In this talk, I will reveal how the paradigm disregards decades of architectural wisdom and rewards misbehaviour from the FaaS provider. These issues require a rethink of the hardware and software stack to make today's markets more efficient and to enable the applications of tomorrow that will make FaaS shine in the post-Moore era.

  To prototype these changes, we need to build full-stack prototype systems ready to run complex virtualised or containerised applications like FaaS, as high-level simulation alone abstracts away the complex system interactions. I will introduce OpenPiton, our open-source manycore research platform used to evaluate architecture research ideas for the cloud and beyond. OpenPiton enables the exact kind of full-stack system-on-chip prototyping we need in a push-button way, making it ideal for evaluating serverless applications and future research ideas. By embracing open-source hardware, the platform reduces the barrier to entry for new users across Computer Science and Electrical Engineering and creates a nexus where research ideas can come together to build a single coherent system.

  One example of such a system I will introduce is our "Bring Your Own Core" (BYOC) platform for enabling heterogeneous-ISA systems research. BYOC enabled the development of both the first open-source, general-purpose, heterogeneous-ISA processor and the first open-source, SMP Linux-booting RISC-V manycore. By providing our novel interface for the connection of processor cores, one can bring a core of their choice and turn it into a heterogeneous manycore system with minimal effort. With this we have built multiple heterogeneous-ISA prototypes and connected ten cores of ISAs including RISC-V, X86, and SPARC. BYOC brings the potential to break down the ISA barrier, treating it as "just another interface" in the broader system stack, and to enable a new class of application-optimised heterogeneous systems to live alongside emerging application-specific accelerators.

  Biography

  Jonathan Balkind is a PhD Candidate in Computer Science at Princeton University. His research interests lie at the intersection of Computer Architecture, Programming Languages, and Operating Systems. He is the Lead Architect of OpenPiton and its heterogeneous-ISA descendent, BYOC, which are productive research platforms with thousands of downloads from over 70 countries worldwide. In developing Piton (a 25-core OpenPiton ASIC), Jonathan's verification effort helped ensure a functional, Linux-booting chip, a notable accomplishment for a small academic team's first chip. Jonathan was also a developer of FaaSProfiler, a tool for profiling Function-as-a-Service "serverless" applications. His research on FaaS unveiled a series of architectural problems with today's FaaS workloads which will only be effectively addressed through hardware-software co-design. Jonathan was a Class of 2018 Siebel Scholar and recipient of the Gordon Y.S. Wu Fellowship in Engineering. He received his Master's in Science in Computing Science with Honours of the First Class from the University of Glasgow in June 2013. He has completed internships at Samsung Electronics (Suwon, South Korea), Arm Ltd (Cambridge, UK), and Microsoft Research (Cambridge, UK).

  CS Seminar: Hardware-Aware Efficient Primitives for Machine Learning (Dan Fu)

  Department of Computer Science (CS)

  12:00 PM 3514, Mudd Hall ( formerly Seeley G. Mudd Library)

  EVENT DETAILS

  

  Friday / CS Seminar
  April 19th / 12:00 PM
  In Person / Mudd 3514

  Speaker
  Dan Fu, Stanford University

  Talk Title
  Hardware-Aware Efficient Primitives for Machine Learning

  Abstract
  Efficiency is increasingly tied to quality to machine learning, with more efficient training algorithms leading to more powerful models. However, today's most popular machine learning models are built on asymptotically inefficient primitives. For example, attention in Transformers scales quadratically in the input size, while MLPs scale quadratically in model dimension. In this talk, I discuss my work on improving the efficiency of the core primitives in machine learning, with an emphasis on hardware-aware algorithms and long-context applications. First, I focus on replacing attention with gated state space models (SSMs) and convolutions, which scale sub-quadratically in context length. I describe the H3 (Hungry Hungry Hippos) architecture, a gated SSM architecture that matches Transformers in quality up to 3B parameters and achieves 2.4x faster inference. Second, I focus on developing hardware-aware algorithms for SSMs and convolutions. I describe FlashFFTConv, a fast algorithm for computing SSMs and convolutions on GPU by optimizing the Fast Fourier Transform (FFT). FlashFFTConv yields up to 7x speedup and 5x memory savings, even over vendor solutions from Nvidia. Third, I will briefly touch on how these same techniques can also be used to develop sub-quadratic scaling in the model dimension. I will describe Monarch Mixer, which uses a generalization of the FFT to achieve sub-quadratic scaling in both sequence length and model dimension. Throughout the talk, I will give examples of how these ideas are beginning to take hold, with gated SSMs and their variants now leading to state-of-the-art performance in long-context language models, embedding models, and DNA foundation models.

  Biography
  Dan Fu is a PhD student in the Computer Science Department at Stanford University, where he is co-advised by Christopher Ré and Kayvon Fatahalian. His research interests are at the intersection of systems and machine learning. Recently, he has focused on developing algorithms and architectures to make machine learning more efficient, especially for enabling longer-context applications. His research has appeared as oral and spotlight presentations at NeurIPS, ICML, and ICLR, and he has received the best student paper runner up at UAI.

  CS Seminar: AI Powered Movement Analysis, Big Rehabilitation Data and a Path to Precision Rehabilitation (R. James Cotton)

  Speaker
  R. James Cotton, Northwestern University & Shirley Ryan AbilityLab

  Talk Title
  AI Powered Movement Analysis, Big Rehabilitation Data and a Path to Precision Rehabilitation

  Abstract
  This talk will discuss multiple methodological lines of work making movement and gait analysis more clinically accessible and biomechanically grounded. This includes reconstruction from synchronized multiview videos, smartphone videos, and wearable sensors. We will also discuss how implicit functions provide a powerful representation to map from time to joint angles, and GPU accelerated methods that enable end-to-end biomechanical fits from these different modalities. It will discuss some of the opportunities that large movement data enables, including the use of self-supervised learning to discover gait representations that can function as both diagnostic and response biomarkers. Finally, we will outline a vision for a Causal Framework for Precision Rehabilitation that can model this data to link from impairment to function and identify the optimal dynamic treatment policies to improve rehabilitation outcomes.

  Biography
