Operational scheme of the LUPPI pipeline, including its main elements: initialization (A) of the observation parameters, the data processing cycle organized in threads around a shared memory and communicating through semaphores, and post-processing of the observation with production of “quicklook” plots. The network thread (B) catches the packets sent by the beamformer, the computing thread (C) processes the data in the Fourier domain on GPUs, and the write thread (D) exports data products to disks.
