The ReadoutCard userspace driver for the new Alice O2 computing system
2021
IEEE Transactions on Nuclear Science
The ALICE (A Large Ion Collider Experiment) experiment focuses on the study of the quark-gluon plasma as a product of heavy-ion collisions at the CERN LHC (Large Hadron Collider). During the Long Shutdown 2 of the LHC in 2019-2020, a major upgrade is underway in order to cope with a hundredfold input data rate increase with peaks of up to 3.5 TB/s. This upgrade includes the new Online-Offline computing system called O 2 . The O 2 readout chain runs on commodity Linux servers equipped with
