Abstract

Current topics in computing for data acquisition, control, and trigger systems for high energy physics experiments are discussed with emphasis on those topics presented in papers submitted to the International Conference on Computing in High Energy Physics, Berlin, April 7–11, 1997.

Highlights

  • Fifty-one high quality presentations and posters on the topics of data acquisition, control, and trigger systems were presented at the International Conference on Computing in High Energy Physics, held in Berlin in April 1997

  • These presentations covered architectures, algorithms, implementations, and tools, as well as both hardware and software topics. They covered a wide variety of subjects ranging from highly technical topics such as custom gallium arsenide adder circuits and how to select an implementation of CORBA to broad topics such as high-performance architectures and software for distributed processing

  • Higher level triggers are based on network switches and processor farms in order to achieve high performance data transport and processing
