#   ** Simple script to compile the code MC-GPU v1.3.
#      For information on how to compile the code for the CPU or using MPI, read the
#      file "make_MC-GPU_v1.3.sh".
#
#      The installation paths to the CUDA toolkit and SDK (http://www.nvidia.com/cuda) 
#      and the MPI libraries (openMPI) may have to be modified by the user. 
#      The zlib.h library is used to allow gzip-ed input files.
#
#      Default paths:
#         CUDA:  /usr/local/cuda
#         SDK:   /usr/local/cuda/samples
#         MPI:   /usr/include/openmpi
