2024


Career: It is official: I'll start my sabbatical this coming September and I will work for Google for one year. I'm very excited about it and I look forward to experience the working environment at Google! If you are at Google and would like to catch up before I start, please reach out. I will be in the Chicago office.

Teaching: Slides of the ATC class are now up-to-date to the ones used this year. I hope they will help others.

Software: We have released HBC, the first compiler that transforms loop-based nested parallelism into binaries that benefit from heartbeat scheduling. HBC builds upon NOELLE, which is also open sourced.

Teaching: The student's evaluation of CC is out! Take a look at them. Thank you to all students that took the time to share their thoughts about this class.

Conference: I'm very happy to have been invited to serve on the MICRO program committee for 2024! MICRO is a great conference for computer architecture research. Consider submitting your work!

Research: Congratulations to Ishita Chaturvedi for having her paper accepted at ISCA 2024! This work proposes an energy efficient solution to make cores within GPUs Out of Oder.

Teaching: Slides of the CC class are now up-to-date to the ones used this year. I hope they will help others.

Teaching: Ryan Wong and Ethan Havemann won the competition for the best compiler of the year for the CC class. Ryan and Ethan are now in the Hall of Fame of the class. Congratulations!

Research: Congratulations to Nick Wanninger for having his paper accepted at ASPLOS 2024! This work proposes a compiler-runtime co-design to relocate C/C++ memory objects at run-time using memory handles.

Software: We have released GINO, the first parallelizing compiler that includes DOALL, HELIX, and DSWP parallelization techniques! GINO builds upon NOELLE, which is also open sourced.

Research: Congratulations to Celine for having her paper accepted at ICLR 2024! This work is a beautiful integration of large language models and compilers to exploit their relative strengths and overcome their relative weaknesses. I'm very happy about this paper because this is my first collaboration with Celine Lee, Abdulrahman Mahmoud, Michal Kurek, Stephen Chong, and Alexander M. Rush. Also, this is the first work I was involved with my mentors David Brooks and Gu-Yeon Wei since the end of my Post-doc (2015) and I've missed working with them during my pre-tenure journey.

Conference: I'm very happy to have been invited to serve on the ASPLOS program committee for 2025! ASPLOS is a great conference for research that cross hardware/software boundaries. Consider submitting your work!

Research: Congratulations to Yian Su for having his paper accepted at ASPLOS 2024! This work is about a compiler that is capable to automatically generate parallel code that implements the heartbeat scheduling from fork-join parallelism declared in the source code (e.g., with OpenMP). No more hand-writing heartbeat scheduling solutions anymore!

2023


Research: Congratulations to Ziyang Xu for having his paper accepted at OOPSLA 2024! This work is about a profiling infrastructure for memory operations and their dependences to easily generate very efficient and scalable memory profilers. We can now profile memory operations and their dependences with little overhead, finally!

Proud advisor I'm very proud to announce Enrico A. Deiana will join Google after his Ph.D.! congratulations Enrico (and Google for having recognized how good Enrico is!)

Proud advisor I'm very proud Enrico A. Deiana successfully defended his Ph.D. thesis last week. Enrico did a fantastic job both at presenting his research and at answering all questions, I'm very proud of him! I know he will do great in his next chapter of his life, good luck Enrico! Thank you Peter Dinda, Nikos Hardavellas, Robby Findler, Margo Seltzer, and Arthur Maccabe (Barney) for being part of Enrico's committee, we have greatly appreciated your work!

Research: Congratulations to Tommy McMichen for having his paper accepted at CGO 2024! This work is about the first compiler's IR with collections (in SSA) as first-class citizen. This IR, called MemOIR, will make memory-centric analyses and transformations much, much, much easier (and, for many cases, finally possible!)

Research: Our latest co-design between compilers and the underlying OS that aims to replace paging has been accepted to ASPLOS! Congratulations everyone, especially Brian and Souradip!

Research: We started the NOELLE project in 2016 as an accelerator for doing compiler research (building a research prototype directly upon LLVM was taking too long for us). We built several compilers upon it over the last 5 years, which allowed us to publish several research prototypes (e.g., CCK, CARAT, CPF, PRVJeeves, Time Squeezer, and many more are coming :) ). While this was gratifying, it didn't feel complete because we haven't published a paper about NOELLE yet. Until now :)
Our paper describing NOELLE has been accepted to CGO this year! This was a significant engineering effort from many people over 5 years, so congratulations to everyone!
We open sourced NOELLE with the hope it can help others as well.
