  1. Install GooFit.

go to some folder, say bx-GooStats/..

# first login to node with GPU / qsub -I to GPU queue !!
mkdir build_GooFit
cd build_GooFit
cmake ../bx-GooStats/GooFit -DCMAKE_INSTALL_PREFIX="../GooFit-install"
make -j
make -j install

that's it.

  1. Test the installation

     cd ../
 mkdir build_GooFitTest
 cd build_GooFitTest
 export GOOFIT_DIR="$(pwd)/../GooFit-install"
 cmake ../bx-GooStats/GooFit/test -DCMAKE_MODULE_PATH="$(pwd)/../bx-GooStats/cmake"
 make -j
 ./exp

This is a binned likelihood fitting. The fit function is [0]*exp([1]*x). The fit will be performed twice, the first is with ROOT/CPU and the second is with GOOFIT/GPU, and the result should be [0] ~ 500 , [1] ~ -0.5
