A real-time application for the CS-2

Abstract

Future high energy experiments planned at CERN for the next-generation collider like LHC will generate amounts of data which are orders of magnitude larger than those produced by existing systems. A trigger system is used to reduce these data in real-time to an amount which can be stored on mass storage for later off-line analysis. Due to the high bandwidth and short latency constraints the solution will most probably consists of a parallel processing implementation. We describe an implementation of the second-level trigger on a commercial multiprocessor system, the Meiko CS-2. Measurements show that such systems are able to reach about 25 to 30 % of the required performance today, which makes them a promising candidate for a complete solution in the next few years.
