Job Description

As one of Europe's leading facilities for high-performance computing, HLRS is a diverse community of scientists, engineers, and other professionals focused on discovering and developing new applications of powerful digital technologies and computer science methods.

HammerHAI — The AI Factory for Industry and Science

-------------------------------------------------------



The HammerHAI project offers to establish an AI Factory at the High-Performance Computing Center Stuttgart (HLRS), supported by a strong consortium from Germany, to successfully meet the growing demand for artificial intelligence (AI) infrastructure across Europe. HammerHAI is be a one-stop shop for many AI users, focusing primarily on start-ups, small and medium-sized enterprises (SMEs), and large industrial companies, as well as supporting academic institutions and the public sector. It offers tailored services and infrastructure to accelerate AI innovation and help develop a competitive AI ecosystem in Europe. The AI Factory is located in a region that is one of Europe’s powerhouses in manufacturing and engineering innovation, and it integrates into an ecosystem that promotes talent building that will be the basis of an ongoing digital transition.



The AI Factory HammerHAI will provide secure, scalable, and AI-optimised supercomputing resources to meet the needs of start-ups, SMEs, industry, and research institutions. Its infrastructure will enable users to easily migrate their AI applications from laptops or cloud environments to supercomputers, providing the computing power needed to develop large-scale AI models. Hereby, the AI Factory supports the entire AI lifecycle, from data preparation to model training, deployment, monitoring, and retraining, and provides a comprehensive package of services to ensure efficient and effective AI development and operation.
