sarrvesh / cuFFS

A GPU-accelerated Rotation Measure Synthesis code

CUDA-accelerated Fast Faraday Synthesis (cuFFS)

Dependencies

• gcc
• libconfig
• cfitsio
• OpenMP
• gnuplot (Optional)
• nvcc (Need both the driver and the toolkit)
• hdf5

Installation

See build.sh for sample compiler instruction.

Notes

• The code assumes that the pixels values are IEEE single precision floating points (BITPIX=-32)
• The input cubes must have 3 axes (2 spatial dimensions and 1 frequency axis) with frequency axis as NAXIS1. If you have individual stokes Q and U channel maps, use the helper/makeFitsCube.py to get the data in the required format.
