Abstract

A data acquisition system in almost all the high energy physics experiments is now requires high performance, i.e. a high speed data transfer, a high speed calculation for a data reduction, and so on. In order to achieve these requirements, a DAQ system based on multi-CPU will be applied. Several kinds of systems have lots of CPUs in not only an event building part but also a front-end one to reduce data. The number of CPUs will be more than 1,000 for such systems. However, it is not so easy to manage such a large number of CPUs. We have developed a management system for a multi-CPU based DAQ system. This system manages to boot up CPUs and to control and monitor them in the DAQ system. The management system consists of one root-server and several co-servers, which are connected with a cascade topology for a high scalability of the system. The system enables us to manage the multi-CPU based DAQ system easily.
