Plugin catalogue

An EDD plugin is an independently versioned Ansible Galaxy collection. It may provide processing pipelines, device controllers, writers, interfaces, dashboards, container build roles, and provision tests. A site pins its plugin set in EDD_PLUGINS and uses fully qualified role names in provision files.

The pages below document the implementations inspected in the accompanying working tree. Production behaviour is determined by the versions pinned in the site inventory; compare those versions before copying an example.

Plugin selection

Major capabilities

Plugin	Primary capability	Typical products
Gated spectrometer	Spectroscopy and spectropolarimetry with noise-diode gating	Gated power, coherences, or Stokes spectra
Pulsar	Coherent timing, searching, voltage recording, and LEAP processing	PSRFITS archives/filterbanks or DADA voltage files
DBBC	Software-defined VLBI backend	Down-converted subbands, VDIF files or UDP, Field System integration
CBF	Array correlation and beamforming	Voltage beams, power beams, full-Stokes beams, and visibilities
HDF5 writer	Generic EDD stream recording	HDF5 files
Digitizer controller	Receiver digitizer and packetizer control	Versioned packetized voltage streams

Compatibility rules

Before combining plugins, verify:

• the EDD core version and supported Ubuntu/CUDA suite;

• exact stream format names, versions, units, and timestamp conventions;

• aggregate multicast, disk, memory, and accelerator requirements;

• unique product IDs, DADA keys, message queues, ports, and multicast ranges;

• whether each pipeline is measuring or streaming; and

• whether a downstream writer understands every subdivision of the upstream output.
