Satisfies Acceptance Criteria
Description
LEAP (Rioja, Dodson & Franzen 2018; MN 478, 2337) is a method for evaluating delays for a grid of sources across the sky, from which solutions can be interpolated to arbitrary directions and provided to CSP for beam-forming.The goal is to run it on ionospheric variation timescales, at least for compact configurations. This calls for a high performance implementation, that exploits data parallelism to suffice the real time constraint.
For proof of concept a CPU-based prototype has been put together, which serves as a starting point and reference when porting it to CUDA.
