Clément Fournier received his engineering degree in Software Engineering from INSA Rennes and his Computer Science Diplom from TU Dresden in July 2022. In 2021, he wrote his diploma thesis on the Rust implementation of the Lingua Franca coordination language. In 2022, he did an internship at Xilinx (then AMD), working on an MLIR-based neural network compiler.
In September 2022, he joined the chair as a research assistant. He works on high-level compiler frameworks (like MLIR) and programming models like Lingua Franca. He focuses on the compilation of neural network and related tensor algebra programs onto recent non-von Neumann platforms, like AMD's AI Engines.
2024-09 I am currently working on a dataflow representation for compilation of neural networks. Please drop me an email if you are interested in compiler implementation (in the MLIR C++ framework), we can talk about an appropriately sized topic.

Abstract
Actor frameworks and similar reactive programming techniques are widely used for building concurrent systems. They promise to be efficient and scale well to a large number of cores or nodes in a distributed system. However, they also expose programmers to nondeterminism, which often makes implementations hard to understand, debug, and test. The recently proposed reactor model is a promising alternative that enables deterministic concurrency. In this paper, we present an efficient, parallel implementation of reactors and demonstrate that the determinacy of reactors does not imply a loss in performance. To show this, we evaluate Lingua Franca (LF), a reactor-oriented coordination language. LF equips mainstream programming languages with a deterministic concurrency model that automatically takes advantage of opportunities to exploit parallelism. Our implementation of the Savina benchmark suite demonstrates that, in terms of execution time, the runtime performance of LF programs even exceeds popular and highly optimized actor frameworks. We compare against Akka and CAF, which LF outperforms by 1.86x and 1.42x, respectively.
