And we just won the outstanding paper award at the MLArchSys workshop this year! Congrats Charles, @sahilb17 and @Sophia_Shao_! 🎉🎉
In this work, we show how to use off-the-shelf LLMs to generate code for accelerators. This is interesting as accelerators are often "low resources," i.e., there isn't much code written using such accelerators to train custom models. Check out our paper for details!.

happening now at NeurIPS!.
We’re excited to present our work on Verified Code Transpilation using LLMs at #NeurIPS2024 today! 🤖🔍 Come visit our poster in the East Exhibit Hall A-C #2904 from 11AM-2PM.

Many streaming systems out there lack formal semantics. Check out Flo, our semantics framework for reasoning about streaming systems. We've used it to reason about DBSP, Flink, and our very own .
Thrilled to share that our paper “Flo: A Semantic Foundation for Progressive Stream Processing” (with @mbpmilano, @alvinkcheung, and @joe_hellerstein) will appear at POPL 2025! Check out the preprint at and read on for more!

Humbly honored to receive the Dahl-Nygaard Junior Prize @ECOOPconf this year. Thank you AITO, and all the great students, mentors, and colleagues I have the fortune to learn from. Excited that our work is recognized by both the PL and DB communities!

Do you use the cloud to run your LLMs? Check out Mélange, our tool that tells you what mix of GPUs you should use for your deployment:

Unlike text, code is highly structured. We just released a new benchmark and leaderboard for fill-in-the-middle coding tasks, with splits based on code structures to be generated. Models should be "code structure aware" to do well. Submit your best models!

ICYMI like last year there are **two** deadlines for ECOOP in 2024. It's an awesome conference. Submit your best work to @ECOOPconf !.
I hope you’ll find our new reviewing model attractive as an author, & I encourage you to submit your work so it can be part of the great program we’ll be publishing in ECOOP 2024! Again, ECOOP papers are due on January 17 (round 1) and April 17 (round 2).

Can functional dependencies only be discovered using ML? Turns out many of them are hidden in app code! Lily will be presenting Coco this afternoon at #VLDB2023, where we analyze code to extract FDs and use a "search and verify" algo to rewrite queries.
