Abstract:One of the goals of the RD13 project at CERN is to investigate the feasibility of parallel switch-based event building systems for LHC detectors. First Studies have been carried out by building a proto- type using the HiPPI standard and by modelling the prototype and extended architectures with MODSIM II.
The prototype uses commercially available VME-based HiPPI modules and a HiPPI switch, and has been tested successfully in different configurations and with different data flow control schemes. The total data throughput is about 40 MB/s and scales with the number of destinations due to the modular structure of the software. The simulation program is written in MODSIM II and was used to understand the measurements with which it shows good agreement. The program could then be used to simulate large-scale event buil- ding systems and to extend it to simulations of event building sys- tems using the FibreChannel standard.
