Abstract
SCI’s ultra low latency and high bandwidth [11] make it a possible candidate to solve the problem of interconnecting a large number of processors in order to filter data produced in high energy physics experiments. In particular this chapter focuses on prototyping for the second level trigger system of the ATLAS experiment [2], at the European Laboratory for Particle Physics (CERN).
After a brief introduction to the problem of real-time data selection in HEP experiments in Section 23.2, Section 23.3 presents the definition, design, implementation and test of a low-level Application Programming Interface (API) for SCI. In Section 23.4 and 23.5 the higher-level application software, the overall architecture of the system and their evolution are described.
