“…The result of each collision, which we call a collision event, is detected, filtered, and transported to a selected computer that resides in what is called a farm of computers, i.e., a very large number of computers running identical analysis programs. The system component that is responsible for these tasks is called the event builder [5].…”

Simulation is an essential tool in the development, testing, and performance evaluation of communication systems. In this paper we discuss a practical case where large ATM switches are needed and develop a cell-level simulator to evaluate the performance of such switches. We exploit the conservative time-window algorithm for parallel simulation to reduce the simulation time and resolve the memory limitation problem with sequential machines. We simulate ATM switches of sizes up to 1 k x 1 k ports. A speed-up of 7 using ten processors on a shared-memory multiprocessor is achieved.

switching network and the specific problems caused by this ATM switching fabrics are good candidates to implement high performance parallel event builders for the future data acquisition systems in particle physics experiments. We are studying their feasibility through simulations and implementation of event builder demonstrators. We present results from performance measurements made with a demonstrator based on a commercial ATM switch and on network interfaces that we have developed. The measurements are compared with the simulation studies and their scalability is discussed.
