| Abstract: |
The ASTRI Mini-Array project, led by the Italian National Institute for
Astrophysics, aims to construct and operate nine Imaging Atmospheric Cherenkov
Telescopes for high-energy gamma-ray source study and stellar intensity interferometry. Located at the Teide Astronomical Observatory in Tenerife, the project’s software
is essential for remote operation, emphasizing the need for prompt feedback on observations. This contribution introduces the Online Observation Quality System (OOQS)
as part of the Supervisory Control And Data Acquisition (SCADA) software. OOQS
performs real-time data quality checks on data from Cherenkov cameras and Intensity
Interferometry instruments. It provides feedback to SCADA and operators, highlighting abnormal conditions and ensuring quick corrective actions for optimal observations.
Results are archived for operator visualization and further analysis. The OOQS data
quality pipeline prototype utilizes a distributed application with three main components
to handle the maximum array data rate of 1.15 Gb/s. The first is a Kafka consumer
that manages the data stream from the Array Data Acquisition System through Apache
Kafka, handling the data serialization and deserialization involved in the transmission.
The data stream is divided into batches of data written in files. The second component
monitors new files and conducts analyses using the Slurm workload scheduler, leveraging its parallel processing capabilities and scalability. Finally, the process results are
collected by the last component and stored in the Quality Archive. |
