GPU version of HemePure.
The user can either:

1. Run the Full build script (FullBuild.sh), which first builds the dependencies and then compiles the source code or
2. Do these steps as listed here:

Build dependencies before attempting to build hemepure_gpu.

1. Create dep/build/ .
2. In dep/build/ run ccmake -B. -H../ or ccmake .. .
3. Configure using CMake.
4. Run make in dep/build/.

1. Create src/build/.
2. In src/build/ run ccmake -B. -H../ or ccmake .. .
3. Configure using CMake.
4. Run make in src/build/.

IMPORTANT NOTE
Remember to modify the following (in the script FullBuild.sh, or in src/CMakeLists.txt) depending on the GPU compute capability (-gencode arch=compute_70,code=sm_70) of the NVIDIA GPUs available on the system
-DCMAKE_CUDA_FLAGS="-ccbin g++ -gencode arch=compute_70,code=sm_70 -lineinfo --ptxas-options=-v --disable-warnings"

Running the executable can be done in the same way as the CPU version.
Launch a HemeLB simulation with the instruction:
mpirun -n N -in <input file *.xml address> -out
e.g. mpirun -n 4 ./hemepure_gpu -in ./input.xml -out results

A detailed description of the input file and how to run a simulation is provided in the official HemeLB website
http://hemelb.org.s3-website.eu-west-2.amazonaws.com/tutorials/simulation/

The folder cases/bifurcation_hires/ contains:

1. the geometry input file (bifurcation.gmy)
2. the input file for the simulation (input.xml)

The analysis of results can be done following the instructions provided in the official HemeLB website
