SANDS lab

We develop techniques and algorithms for building and managing key networked systems that are worthy of society’s trust. Our core interests lie in improving the modern computing environment where distributed systems and computer networks are a pervasive component.

  • We focus on bridging the gap between the abstractions that users (i.e., software developers, cloud providers, or network operators) need and what a performant, scalable, dependable and deployable system can achieve in practice.
  • We build prototypes that directly improve the lives of real users.
  • We seek solutions based on theoretically grounded arguments while also gaining insights into constraints and trade-offs in the design space.

Our goal is to enrich the human knowledge of how to build future-proof systems that can stand the test of time.

News

  • Aug'23: Chen-Yu (Elton) has defended his PhD thesis titled “Tackling the Communication Bottlenecks of Distributed Deep Learning Training Workloads” and will next join Bytedance (USA). Congratulations!
  • Mar'23: Arnaud has defended his PhD thesis titled “Verification and Privacy Techniques for Improving the Trustworthiness of Neural Networks” and will next join Nokia Bell Labs. Congratulations!
  • LineFS wins the Best Paper Award at SOSP'21.
  • Rethinking gradient sparsification as total error minimization accepted as spotlight paper (top 3%) at NeurIPS'21.
  • We organize a tutorial on Network-Accelerated Distributed Deep Learning at SIGCOMM'21.
  • In our NSDI'21 paper we demonstrated how to accelerate distributed ML via in-network aggregation with SwitchML. In our upcoming SIGCOMM'21 paper introducing OmniReduce, we are advancing streaming aggregation to leverage the sparsity of large models’ gradient vectors to accelerate training.
  • In the GRACE project, we survey popular gradient compression techniques for distributed deep learning and perform a comprehensive comparative evaluation. Read our ICDCS'21 paper.
