dedisp

This repository is derived from Ben Barsdell's original GPU De-dedispersion library (code.google.com/p/dedisp) And forked from https://github.com/ajameson/dedisp. This fork adds an improved (performance) implementation of dedisp, referred to as Time Domain Dedispersion (TDD) and adds a new dedispersion algorithm for Fourier Domain Dedispersion (FDD).

Installation Instructions:

1. Clone the directory
2. Set-up cmake in a build directory, e.g. /build/dedisp
   • $ cmake <source dir path> -DCMAKE_INSTALL_PREFIX=<install dir path>
3. Optionally further configure cmake through interactive build settings
   • $ccmake .
   • e.g. set ENABLE_BENCHMARK to ON to enable build for performance reporting [default: ON]
   • e.g. set DEDISP_DEBUG to ON to enable build with more verbose output (for debugging purposes) [default: OFF]
4. make and install
   • $ make install

This repository has been developed and tested with cmake 3.16.2, gcc 8.3.0 and CUDA 11.0.1
