Abstract :
The central detectors of the ALICE experiment at LHC will produce a data size of up to 75 MB/event at an event rate ⩽200 Hz resulting in a data rate of ∼15 GB/s. Online processing of the data is necessary in order to select interesting (sub)events (“High Level Trigger”), or to compress data efficiently by modeling techniques. Processing this data requires a massive parallel computing system (High Level Trigger System). The system will consist of a farm of clustered SMP-nodes based on off-the-shelf PCs connected with a high bandwidth low latency network.
