The 17th International dCache workshop 2023 will take place from 2023-05-31 to 2023-06-01 in person and hosted by the HTW Berlin - University of Applied Sciences. As with earlier workshops, the dCache team is eager to maintain and strengthen the relationship to dCache system administrators, experienced or novice. Contributions to the workshop will focus on presenting mechanisms helping sysadmins to run secure and fault tolerant dCache systems.

6 On how CC-IN2P3 intends to use dCache for digitizing the Universe

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.

Speakers: Mr Adrien Georget (IN2P3), Mr Fabio Hernandez (IN2P3)
