Description
Fast Radio Bursts (FRBs) are millisecond dispersed radio pulses of predominately extra-galactic origin. Despite hundreds of FRBs discovered at frequencies above 400 MHz, only a few were discovered below 400 MHz. One of the reasons is computational complexity of low-frequency FRB searches over wide fields of view (hundreds or thousands of square degrees) and long dispersion delays (of the order of tens of seconds). I will present a recently developed imaging software BLINK utilising modern Graphical Processing Units (GPUs), which is intended to address some of these issue. The primary target instruments are the MWA and SKA-Low prototype station EDA2. BLINK imager can be compiled in either NVIDIA or AMD GPU programming frameworks on HPC or server/desktop architectures. It is intended to become a part of a GPU-based processing pipeline, which will correlate voltages recorded by a telescope (in real-time or off-line), apply calibration, form images and perform FRB and transient searches. The software will be executed entirely on GPU in order to minimise I/O operations and copying memory to and from the GPU. Hopefully, this work will enable first ever detections of low-frequency FRBs with the SKA-Low precursors in the Southern Hemisphere!
