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.
My collaborators and I will have three papers on programmable switches appearing in NSDI'22!
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.
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.
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!
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.
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.
I’m currently chairing USENIX HotCloud 2019. Looking forward to exciting submissions on early-stage work and new research directions!
