DUNE-DAQ
DUNE Trigger and Data Acquisition software
|
This package extends the schema from the confmodel package to describe readout, dataflow and trigger applications.
SmartDaqApplication is an abstract class that has no direct relationships with DaqModules. The DaqModules themselves must be generated on the fly by an implementation of the generate_modules()
method. The SmartDaqApplication has relationships to QueueConnectionRules and NetworkConnectionRules to alow the generate_modules()
method to know how to connect the modules internally and to network endpoints.
NB: The declaration of the generate_modules()
method must be repeated in each subclass and an implementation provided. The declaration in SmartDaqApplication is not pure virtual but its implemetation calls the generate_modules() implementation of the specific subclass using a 'magic' map of class names to generate functions.
Readout, HSI, Hermes andDataflow and Trigger applications extend from SmartDaqApplication
The ReadoutApplication inherits from both SmartDaqApplication and ResourceSetAND. This means it has a contains relationship that can contain any class inheriting from ResourceBase but should only contain DetectorToDaqConnection**s. The generate_modules()
method will generate a **DataReaderModule for each DetectorToDaqConnection associated with the application, and set of DataHandlerModule objects, i.e. DLH for each DetectorStream plus a single TPHandlerModule (FIXME: this shall become a TPHandler per detector plane). Optionally DataRecorderModule modules may be created (not supported yet)). The modules are created according to the configuration given by the data_reader, link_handler, data_recorder and tp_handler relationships respectively. Connections between pairs of modules are configured according to the queue_rules relationship inherited from SmartDaqApplication.
Several OKS classes have far detector specific customisations, as shown in the diagram.
The Datflow applications, which are also SmartDaqApplication which generate DaqModules on the fly, are also included here.
The Trigger applications, which are also SmartDaqApplication which generate DaqModules on the fly, are also included here.
The WIEC application is a SmartDaqApplication which generates HermesModule modules , and in future WIB modules, on the fly. It extends from ResourceSetAND and contains DetectorToDaqConnection**s, which each contains a **DetDataReceiver and **DetDataSender**s containing **DetectorSrteam**s.
This package also provides a program generate_modules_test
for testing the generate_modules method of SmartDaqApplications. It reads a configuration from an OKS database, generates the DaqModules for the requested SmartDaqApplication and prints a summary of the DaqModules and Connections.
