In this contribution we will present how CC-IN2P3 is preparing to use a dedicated instance of
dCache to help produce the Legacy Survey of Space and Time (LSST) of the Vera C. Rubin
Observatory. We will present how we intend to use dCache for both inter-site data exchange
and for serving data to image processing pipelines running locally in the batch farm and for
storing their products. We will highlight how our usage differs from the typical usage of dCache
made by the LHC experiments also supported by the site.
The Rubin observatory is in its final phase of construction in the Andes mountains in Chile and
due to start operations in early 2025 for 10 years. Its 8.4-meter telescope will nightly scan the
southern sky and collect images of the entire visible sky every 4 nights using a 3.2 Gigapixel
camera, the largest imaging device ever built for astronomy. Automated detection and
classification of celestial objects will be performed by sophisticated algorithms on
high-resolution images to progressively produce an astronomical catalog eventually composed
of 20 billion galaxies and 17 billion stars and their associated physical properties.
