Description
The Allen Telescope Array is a radio interferometer array located in Northern California. Each of the 42 antennas is 6 meters in diameter and is distributed randomly over an area of 350 meters. Each dish is sensitive to an ultra-wideband frequency range from 200 MHz to 12 GHz. While in operation, each dish can produce 1.5 GHz of bandwidth for each polarization adding up to 1.3 Tbps of data.
The huge amount of data produced each second by the telescope has to be processed in real time on-site. This talk will demonstrate how we are combining pre-existing software such as the Breakthrough Listen Accelerated DSP Engine (BLADE) with the NVIDIA Holoscan SDK to create the next-generation data processing pipeline at the ATA. This new architecture helps leverage the full power of the hardware by using Remote Direct Access Memory (RDMA) to facilitate data transfers between the network interface and the graphics card. Also, the extra flexibility provided by Holoscan helps to deploy new processing pipelines faster, and by using its powerful abstractions, deploy machine learning-based algorithms alongside traditional ones.
