The package

GooFit is a powerful, fast fitting library designed to mimic the familiar syntax of ROOT’s RooFit. The code and installation instructions are available here, on GitHub, and a description of the fitting process and API is available on GitHub IO.

Docker builds

The development version of GooFit is available through Docker as well. To use the OpenMP version:

docker run -it goofit/goofit-omp

And, the CUDA version:

nvidia-docker run -it goofit/goofit-cuda

This will put you in a /GooFit folder. You should git pull the latest changes, and then go to /GooFit/build and rebuild. If you have a GooFit Package, you can check it out to /GooFit/goofit_*. If you want to persist you session, you should use Docker to mount a volume or folder.

The source for the docker builds is available on GitHub.
