Powerful mainstream computing equipment and the advent of affordable multi-Gigabit communication technology permit us to address data acquisition problems with clusters of inexpensive computers. Such networks typically incorporate heterogeneous platforms, real-time partitions and custom devices. We strive therefore for a software infrastructure that(More)
Mainstream computing equipment and the advent of affordable multi-Gigabit communication technology permit us to address data acquisition and processing problems with clusters of COTS machinery. Such networks typically contain heterogeneous platforms, real-time partitions and even custom devices. Vital overall system requirements are high efficiency and(More)
Powerful mainstream computing equipment and the advent of affordable multi-Gigabit communication technology allow us to tackle data acquisition problems with clusters of inexpensive computers. Such networks typically incorporate heterogeneous platforms, real-time partitions and custom devices. Therefore, one must strive for a software infrastructure that(More)
Mainstream computing equipment and the advent of affordable multi-Gigabit communication technology permit us to address grand-challenge data acquisition and processing problems with clusters of inexpensive computers. Such networks typically incorporate heterogeneous equipment, real-time partitions and even custom devices. Vital overall system requirements(More)
The data acquisition system for the CMS experiment at the Large Hadron Collider (LHC) will require a large and high performance event building network. Several switch technologies are currently being evaluated in order to compare different architectures for the event builder. One candidate is Myrinet. This paper describes the demonstrator which has been(More)
Traditional systems dominated by performance constraints tend to neglect other qualities such a maintainability and configurability. Object-Orientation allows one to encapsulate the technology differences in communication subsystems and to provide a uniform view of data transport layer to the systems engineer. We applied this paradigm to the design and(More)
