The Fourier domain acceleration search (FDAS) is an effective technique for detecting faint binary pulsars in large radio astronomy data sets. This paper quantifies the sensitivity impact of reducing numerical precision in the graphics processing uni... Read More about Bits Missing: Finding Exotic Pulsars Using bfloat16 on NVIDIA GPUs.

We present an implementation of the overlap-and-save method, a method for the convolution of very long signals with short response functions, which is tailored to GPUs. We have implemented several FFT algorithms (using the CUDA programming language),... Read More about GPU Fast Convolution via the Overlap-and-Save Method in Shared Memory.
