Mission confiée
Artificial Intelligence (AI) is increasingly indispensable across various society sectors due to its potential to transform conventional applications, from smart homes to safety-critical systems like autonomous driving and space exploration. Deep neural networks (DNNs) are state-of-the-art AI methods that outperform other approaches in language processing, image and video classification, audio and radar processing, and instance segmentation [1-3]. Notably, DNNs such as OpenAI GPT-4, Meta LLaMA2, and Mistral Mixture of Experts have captivated public interest with their high accuracy.
Due to their resource-intensive nature, DNNs require powerful dedicated hardware accelerators, such as GPUs and TPUs. However, large hardware accelerators are unsuitable for embedded safety-critical systems due to their high energy consumption. New unconventional accelerator architectures like the ones based on PIM [4] and neuromorphic computing [5] have been proposed for complex DNN deployment in critical applications where power and performance are critical requirements, offering energy-efficient alternatives to traditional GPUs and TPUs. However, their reliability, particularly against radiation-induced faults, remains to be fully assessed.
In this Ph.D., we will identify hardware and software vulnerabilities in PIM accelerators for DNNs and propose fault mitigation techniques.
Principales activités
Activities
The Ph.D. student will characterize the radiation-induced impact on system reliability for different DNN model architectures and how the acceleration that PIM enables impacts the final error rate. The results will be combined with software simulation data for a detailed fault propagation analysis, aiming at deploying effective hardening solutions tailored for PIM executing DNNs.
The Ph.D. student will participate in international experiments and internships at laboratories like Rutherford Appleton Laboratory in the UK and Los Alamos National Laboratory in the USA. The student will participate in conferences and international projects and have their research published in prestigious scientific venues. This will help them develop their research skills and network with professionals in their field.
