Description
Jean Zay, hosted at IDRIS, provides large-scale computing resources for AI research. This talk will offer a practical introduction for the IN2P3 and CEA-IRFU communities, focusing on the resources available and the steps required to access and use them effectively.
I will present the computing resources and software environment, together with an outlook on future capabilities. The presentation will address both administrative and technical aspects of access: eligibility, allocation schemes, proposal preparation and evaluation, and the practical steps from obtaining an account to running AI workloads. Particular attention will be paid to demand for computing time and its implications for applicants, including how to estimate computational needs and formulate realistic, well-justified resource requests. I will also discuss practical considerations for GPU-based and distributed workloads, as well as the user support and training available at IDRIS.
A few examples drawn from cosmology, including emulation and simulation-based inference, will illustrate relevant use cases and their computational requirements. The aim is to help participants assess whether Jean Zay is a suitable platform for their AI projects and identify a clear path from an initial idea to a computing allocation and their first runs.
