First Level Processor (FLP)

The O2/FLP project addresses the challenge of reading out the Pb–Pb collisions at rates of 50kHz, sampling the pp and p–Pb at up to 1 MHz. The resulting data throughput from the detector has been estimated to be greater than 3TB/s for Pb–Pb events, roughly two orders of magnitude more than in

The O2/FLP project is in charge of the FLP farm, the detector readout software, the data quality control system (QC) and the general computing services such as the experiment control system (ECS) and the monitoring/configuration/logging infrastructure.

In terms of operations, the O2/FLP project includes 2 Subsystem Run Coordinators: FLP and QC.
