Bookkeeping, a new logbook system for ALICE / Boulais, Martin (CERN) ; Raduta, George C (CERN) ; Huijberts, Jik (CERN)
The ALICE experiment at CERN’s Large Hadron Collider is designed to study the physics of strongly interacting matter at extreme energy densities, where a quark-gluon plasma is expected to be formed. After a major upgrade, the new ALICE Online-Offline computational system expects to read an estimated throughput of 3.5TB/s of raw data and store and index 900Gb/s reconstructed data. [...]

Commissioning of the ALICE readout software for LHC Run 3 / Chapeland, Sylvain (CERN) /ALICE Collaboration
ALICE (A Large Ion Collider Experiment) is a heavy-ion detector studying the physics of strongly interacting matter and the quarkgluon plasma at the CERN LHC (Large Hadron Collider). During the second long shut-down of the LHC, the ALICE detector was upgraded to cope with an interaction rate of 50 kHz in Pb-Pb collisions, producing in the online computing system (O2) a sustained input throughput of 3.5 TB/s.In the past years, the O2/FLP project built the new data-acquisition system capable of handling this load. [...]

The ALICE Data Quality Control / von Haller, Barthélémy (CERN) ; Konopka, Piotr (CERN) /ALICE Collaboration
ALICE (A Large Ion Collider Experiment) has undertaken a major upgrade during the Long Shutdown 2. The increase in the detector data rates, and in particular the continuous readout of the TPC, led to a hundredfold increase in the input raw data, up to 3.5 TB/s. [...]
