Abstract

The STAR level-3 trigger system will perform online track finding for high multiplicity Au+Au collider events (N_track≥8000, N_point≤45 per track), utilizing high-performance ALPHA 21264 CPUs and high-bandwidth MYRINET network interfaces (expected data transfer rate≈52 Mbytes/s). A global level-3 CPU will perform tasks like online invariant mass reconstruction and issue an accept/reject decision with a design input rate R = 100 Hz (R≤25 Hz for a prototype system in 12/99).
