Abstract :
A VME-based multiprocessor system for online data analysis is presented. The system is based on a master CPU board that distributes incoming event buffers to several slave CPUs running the same analysis program. A large shared memory is provided to hold final histograms. A Vaxstation, linked to the system via Ethernet, provides control and graphics management of the analyzed data. A numerical simulation of the system is described and results are compared with real performance using a prototype of the system
