Rough/Meeting notes
The O2 project stands for Online-Offline. It essentially handles all computing tasks for the ALICE experiment. Including Data Acquisition, Experiment control, Bookkeeping, among countless smaller tasks.
ALICE O2 Data Acquisition and trigger
The job of DAQ is to receive data from the detectors, filter the data, and store in permanent storage. This job requires filtering around 3.5TB/s to 90GB/s.
ALICE O2 Data quality control
The job of data quality control is to ensure data coming off the detectors is valid and correct. They try not take resources away from the main data acquisition pipeline, and use statistical methods, not including machine learning, to validate the data.
ALICE O2 Bookkeeping
This is the project I work on! The bookkeeping project keeps track of runs and environments, and allows the LHC shifters and scientists to keep track of LHC and ALICE events.
