Throughput Computing at Work: Reports from the Field

Speaker

Description

Rubin Observatory will begin conducting the Legacy Survey of Space and Time (LSST), a 10 year survey of the Southern sky. This presentation will briefly cover how the project successfully uses HTCondor based workflows for several flavors of processing, including preparations for the project's Data Release Production at the United States Data Facility.
The project's middleware that interfaces between the user and HTCondor,  a.k.a., Batch Production Service (BPS), will be introduced as well as the "allocateNodes" mechanism being used to submit user glideins to Slurm clusters.
