Abstract
At the upcoming Large Hadron Collider (LHC) at CERN one expects to measure 20,000 particles in a single Pb-Pb event resulting in a data rate of ~75MByte/event. The event rate is limited by the bandwidth of the storage system. Higher rates are possible by selecting interesting events and subevents (Level-3 trigger) or compressing the data efficiently with modeling techniques. Both require a fast parallel pattern recognition. One possible solution to process the detector data at such rates is a farm of clustered SMP nodes, based on off-the-shelf PCs, and connected by a high bandwidth, low latency network.
