Job title
Intelligence Artificielle - Large Language Models optimizations for In-Memory Computing hardware H/F

Subject
Ce stage vise à mettre en place une infrastructure logicielle pour optimiser des modèles de langages (LLMs) afin de permettre leur implémentation sur du matériel performant. En partant d'infrastructures logicielles existantes, le stage vise à y intégrer des méthodes d'optimisation telle que la quantification.

This internship aims at putting together a software infrastructure for mapping, simulating and exploring the performance of Large Language Models (LLMs) on In-Memory Computing (IMC) hardware, starting with existing open-source tools chains and integrating functionalities dedicated to IMC hardware, such as quantization and error models.

Job Description
Large Language Models (LLMs), such as ChatGPT, have led to a new AI revolution with applications in every domain. However, LLMs are very resource-consuming (energy, compute…) and, hence, an important line of research focuses on optimizing these models. Existing open-source tool chains, such as LLM Compressor [1] and OpenVINO [2], enable almost-automatic optimizations to compress LLMs into smaller ones by, e.g., quantization and pruning. However, they only target conventional hardware, such as GPUs. New hardware paradigms, such as In-Memory Computing (IMC) are promising to accelerate and reduce the energy consumption of LLMs [3]. However, running LLMs on such hardware requires specific optimizations due to the characteristics of these hardware. For instance, they require extreme quantization of the model (reducing the number of bits on which data, weigths and activations are encoded), because analogue IMC fabric has a limited number of bits, and optimizing the robustness of the model, because IMC computations are prone to errors. Nevertheless, software tools and methods for mapping state-of-the-art LLMs on these hardware platforms lag behind.

This internship aims at putting together a software infrastructure for mapping, simulating and exploring the performance of LLMs on IMC hardware, starting with existing open-source tools chains and integrating functionalities dedicated to IMC hardware, such as quantization and error models. The student will be integrated within a multidisciplinary team of research engineers, PhDs, PostDocs and interns, at the heart of an ecosystem of industrial and academic partners in the world of embedded AI. He/she will have access to supercomputers infrastructure. He/she will benefit from increased expertise in LLMs, compression methods, and efficient hardware for AI. Leveraging the tools and knowledge developed during the internship, the student could be offered the opportunity to pursue a PhD on compression methods for LLMs.
