make_MC-GPU_v1.5b.sh

#!/bin/bash
# 
#    ** Simple script to compile the MC-GPU code with CUDA, and optionally with MPI **
#
#      The installations paths to the CUDA toolkit and SDK (http://www.nvidia.com/cuda) and
#      the MPI library path may have to be adapted before runing the script.
#      The zlib.h library is used to allow gzip-ed input files.
# 
#      Please set the compilation architecture to the compute capability of your GPU cards!
#
#      Default paths:
#         CUDA:  /usr/local/cuda
#         SDK:   /usr/local/cuda/samples
#         MPI:   /usr/include/openmpi
