  I’m deeply honored to share that the Overshadow paper from ASPLOS 2008 has won the ASPLOS Influential Paper Award!

• 09 December 2024

  Slides from my keynote at APSys 2024 in Kyoto are now (belatedly) available!

• 02 September 2024

  I’ll be giving the keynote at APSys 2024. See everyone in Kyoto!

• 18 November 2022

  Announcing discuss.systems - a Mastodon instance for the greater systems research and practice community

  Open to anyone interested in operating systems, distributed systems, networked systems, or just chatting in general.

  This is being run and moderated by me, Dev, and Irene

• 10 January 2022

  My collaborators and I will have three papers on programmable switches appearing in NSDI’22!

  • FPISA shows how to execute in-switch operations on floating point data
  • SwiSh shows how to implement distributed shared state, including global sketches with bounded error
  • NetVRM shows how to support multitenant applications with dynamic memory reallocation
• 15 April 2021

  Very excited to share that our work on SwitchML is now available. SwitchML shows that distributed ML training workloads are often network-bound, and in-network aggregation using a programmable switch can resolve this bottleneck.

  We’ve released the code as open source through the P4 Consortium, so check that out – or the NSDI 21’ paper, presentation video, or explanation through cat photos

• 18 March 2021

  I recently gave a Distinguished Lecture at the National University of Singapore about Accelerating Distributed Systems with In-Network Computation.

  The recording is now available to watch online.

• 15 November 2020

  On 11/18, Papers We Love is holding a mini-conference to help raise money for USENIX and support open access – a great cause!

  I’ll be speaking on a panel with a number of very distinguished guests!

• 02 November 2020

  Check out our latest work on Pegasus, appearing in OSDI 2020, which shows that a programmable switch can help a key-value store run as efficiently on a skewed workload as a uniform one.

  Paper, source code, and explanation using cat photos are all available.

• 06 May 2020

  I recently gave a keynote about in-network computation at the SPMA workshop at Eurosys.

  Having finally remembered how to update my website, here are three cool new systems:

  • Harmonia (VLDB ‘20) lets replicated storage systems scale their performance linearly with the number of replicas, without sacrificing linearizability, by using a programmable switch as a contention detector.

  • LeapIO (ASPLOS ‘20) is an architecture for efficiently offloading complex cloud storage stacks to ARM-based coprocessors, avoiding the 10-20% “storage tax” CPU overhead that cloud providers pay today.

  • Meerkat is a new multicore-scalable replicated transaction protocol that avoids both cross-core and cross-replica coordination for non-conflicting transactions.

• 15 April 2019

  I’m happy to share this position paper with our take on in-network computing – not just what we can do, but what we should do; what applications it’s good for; and what we need to solve before we can deploy it.

  This will appear in HotOS ‘19.

• 01 March 2019

  I’m currently chairing USENIX HotCloud 2019. Looking forward to exciting submissions on early-stage work and new research directions!
