fdreadoutlibs - Far Detector readout libraries

Collection of Far Detector FrontEnd specific readout specializations. This includes type definitions to be used with the implementations in readoutlibs and frontend specific specializations (i.e. frame processors or software hit finding). It is the glue between readoutlibs and readoutmodules that specifies types and implementations for the use of readoutlibs that can then be imported by readoutmodules to be initialized in the DataLinkHandler module.

Building and setting up the workarea

How to clone and build DUNE DAQ packages, including readout, is covered in the daq-buildtools instructions. For examples on how to run the standalone readout app, take a look at the readoutmodules documentation.

Frontends and features provided by fdreadoutlibs

The following frontends and features are provided by this package:

• Daphne: Frame processor and request handler to be used with the SkipList latency buffer.
• SSP: Only frame processor
• WIB: Frame processor for WIB, software and hardware WIB TPs. Implementation of avx based software hit finding (software tpg) for WIB
• WIB2: Frame processor for WIB2, implementation of avx based software hit finding (software tpg) for WIB2

Test Software TPG on WIB2

To test the execution of the DUNE WIB2 software TPG, first download a raw data file, either by running curl https://cernbox.cern.ch/index.php/s/ocrHxSU8PucxphE/download -o wib2-frames.bin or clicking on the CERNBox link and put it into <work_dir>

Example of daqconf configuration file used for testing:

{
"boot" : {
   "opmon_impl": "cern"
},

"readout": {
   "enable_software_tpg": true,
   "clock_speed_hz": 62500000,
   "data_file": "./wib2-frames.bin",
   "readout_sends_tp_fragments": false
},

"trigger": {
  "trigger_rate_hz": 10,
  "tpg_channel_map": "HDColdboxChannelMap",
  "enable_tpset_writing" : true
},

"dataflow" : {},

"dqm" : {}

}

NOTE: the swtpg was tested with a single link using a local binary input file (AAA 22-09-2022).
