The ATLAS detector, recording LHC particles' interactions, produces events with rate of 40 MHz and size of 1.6 MB. The processes with new and interesting physics phenomena are very rare, thus an efficient on-line filtering system (trigger) is necessary. The asynchronous part of that system relays on few thousands of computing nodes running the filtering software. Applying refined filtering criteria...
