Prototype of a Dedicated Multi-Node Data Processing System for Realtime Trigger and Analysis Applications — •Daniel Kirschner — II. Phys. Inst. Giessen, Heinrich-Buff-Ring 14, 35392 Giessen

Modern experiments in hadron physics like the HADES detector at GSI-Darmstadt produce a large amount of data that has to be distributed, stored and analyzed. Analysis of this data is very time consuming due to the large amount of data and the complex algorithms needed.

One approach to these topics are custom made systems like the GEMN (Gigabit Ethernet Multi Node). The developed prototype features two Gigabit Ethernet connections and a TigerSHARC DSP.

As test for the capabilities of this system an example application in the context of the HADES experiment (@GSI) is presented: online matching of rings in the RICH detector with fired wires in the MDC detector to filter out fake rings and thereby reducing data rate to the storage system and saving time in the offline analysis.

This project is supported by: EU, GSI and BMBF.
