CESG Seminar: Dr. Bo Yuan

4:10 – 5:00 p.m.
via Zoom (link below)
 
Dr. Bo Yuan
Asst. Professor, Dept. of Electrical & Computer Engineering, Rutgers University

Title: “Algorithm and Hardware Co-Design for Efficient Deep Learning: Sparse and Low-rank Perspective”

Talking Points

  • Algorithm and hardware co-design for structured and unstructured deep neural networks
  • Algorithm and hardware co-design for high-order tensor decomposition-based deep neural networks

Abstract
In the emerging artificial intelligence era, deep neural networks (DNNs), a.k.a. deep learning, have gained unprecedented success in various applications. However, DNNs are usually storage intensive, computation intensive and very energy consuming, thereby posing severe challenges on the future wide deployment in many application scenarios, especially for the resource-constraint low-power IoT application and embedded systems. In this talk, I will introduce the algorithm/hardware co-design works for energy-efficient DNN in my group, from both the sparse and low-rank perspectives. First, I will show the benefit of using structured and unstructured sparsity of DNN for designing low-latency and low-power DNN hardware accelerators. In the second part of my talk, I will present an algorithm/hardware co-design framework that leverages low tensor rankness towards energy-efficient high-accuracy DNN model and accelerators.

 ETB 1020 – **In-person**
 
Dr. Craig Robinson
Tech Lead and Manager for Positioning at Waymo

Title: “Waymo Self Driving: An Overview”

Talking Points

    • Self-driving is driven by corner cases
    • Sensor fusion is important; but independence is more useful
    • No problem is too simple

Abstract
We will first give an overview of Waymo, the “Waymo Driver” and the vision for Self-Driving systems we have under development. We will then take a closer look at the current generation vehicle from a technical standpoint and delve into the sensor systems and modalities onboard (radar, laser, camera, IMU’s and microphones(!)). That will lead to a discussion of higher level system architecture (hardware and software) and the safety framework that underpins the system. Finally we will wrap up with some observations from the field regarding differences between research, development and deployment of complex systems like self-driving vehicles.

Title: “Subactive Techniques for Guaranteeing Routing and Protocol Deadlock Freedom in Interconnection”

Talking Points:

    • Correctness is of paramount concern in interconnection networks. (Routing and Protocol) Deadlock freedom is a cornerstone of correctness.
    • Prior solutions either over-provision the network or incur performance penalty to provide deadlock freedom
    • We propose new set of unified techniques to resolve routing and protocol deadlocks

Abstract
Interconnection networks are the communication backbone for any system. They occur at various scales: from on-chip networks, for example 2.5D/chiplet networks, between processing cores, to supercomputers between compute nodes, to data centers between high-end servers. One of the most fundamental challenges in an interconnection network is that of deadlocks. Deadlocks can be of two types: routing level deadlocks and protocol level deadlocks. Routing level deadlocks occur because of cyclic dependency between packets trying to acquire buffers, whereas protocol level deadlock occurs because the response message is stuck indefinitely behind the queue of request messages. Both kinds of deadlock render the forward movement of packets impossible leading to complete system failure.

Prior work either restricts the path that packets take in the network or provisions an extra set of buffers to resolve routing level deadlocks. For protocol level deadlocks, separate sets of buffers are reserved at every router for each message class. Naturally, proposed solutions either restrict the packet movement resulting in lower performance or require higher area and power.

We propose a new set of efficient techniques for providing both routing and protocol level deadlock freedom. Our techniques provide periodic forced movement to the packets in the network, which breaks any cyclic dependency of packets. Breaking this cyclic dependency results in resolving routing level deadlocks. Moreover, because of periodic forced movement, the response message is never stuck indefinitely behind the queue of request messages; therefore, our techniques also resolve protocol level deadlocks. We use the term ‘subactive’ for these new class of techniques.

Dr. Mayank parasar works at Samsung Austin R&D Center (SARC) in Austin, TX. Mayank Parasar has received his Ph.D. from the School of Electrical and Computer Engineering at Georgia Institute of Technology. He received an M.S. in Electrical and Computer Engineering from Georgia Tech in 2017 and a B.Tech. in Electrical Engineering department from Indian Institute of Technology (IIT) Kharagpur in 2013.

He works in computer architecture with the research focus on proposing breakthrough solutions in the field of interconnection networks, memory system and system software/application layer co-design. His dissertation, titled Subactive Techniques for Guaranteeing Routing and Protocol Deadlock Freedom in Interconnection Networks, formulates techniques that guarantee deadlock freedom with a significant reduction in both area and power budget.

He held the position of AMD Student Ambassador at Georgia Tech in the year 2018-19. He received the Otto & Jenny Krauss Fellow award in the year 2015-16.
