-************************************************************************************
-Code_Saturne 4.2.2 is linked to PETSC developer's version, in order to benefit from
-its GPU implementation. Note that the normal release of PETSC does not support GPU.
-************************************************************************************
-Installation
-************************************************************************************
-
-The version has been tested for K80s, and with the following settings:-
-
--OPENMPI 2.0.2
--GCC 4.8.5
--CUDA 7.5
-
-To install Code_Saturne 4.2.2, 4 libraries are required, BLAS, LAPACK, SOWING and CUSP.
-The tests have been carried out with lapack-3.6.1 for BLAS and LAPACK, sowing-1.1.23-p1
-for SOWING and cusplibrary-0.5.1 for CUSP.
-
-PETSC is first installed, and PATH_TO_PETSC, PATH_TO_CUSP, PATH_TO_SOWING, PATH_TO_LAPACK
-have to be updated in INSTALL_PETSC_GPU_sm37 under petsc-petsc-a31f61e8abd0
-PETSC is configured for K80s, ./INSTALL_PETSC_GPU_sm37 is used from petsc-petsc-a31f61e8abd0
-It is finally compiled and installed, by typing make and make install.
-
-Before installing Code_Saturne, adapt PATH_TO_PETSC in InstallHPC.sh under SATURNE_4.2.2
-and type ./InstallHPC.sh
-
-The code should be installed and code_saturne be found under:
-
-PATH_TO_CODE_SATURNE/SATURNE_4.2.2/code_saturne-4.2.2/arch/Linux/bin/code_saturne, which should return:
-
-Usage: ./code_saturne <topic>

-************************************************************************************
-Test case - Cavity 13M
-************************************************************************************
-
-In CAVITY_13M.tar.gz are found the mesh+partitions and 2 sets of subroutines, one for CPU and the
-second one for GPU, i.e.:
-
-CAVITY_13M/PETSC_CPU/SRC/*
-CAVITY_13M/PETSC_GPU/SRC/*
-CAVITY_13M/MESH/mesh_input_13M
-CAVITY_13M/MESH/partition_METIS_5.1.0/*
-
-To prepare a run, it is required to set up a "study" with 2 directories, one for CPU and the other one for GPU
-as, for instance:
-
-PATH_TO_CODE_SATURNE/SATURNE_4.2.2/code_saturne-4.2.2/arch/Linux/bin/code_saturne create --study NEW_CAVITY_13M PETSC_CPU
-cd NEW_CAVITY_13M
-PATH_TO_CODE_SATURNE/SATURNE_4.2.2/code_saturne-4.2.2/arch/Linux/bin/code_saturne create --case PETSC_GPU
-
-The mesh has to be copied from CAVITY_13M/MESH/mesh_input_13M into NEW_CAVITY_13M/MESH/.
-And the same has to be done for partition_METIS_5.1.0.
-
-The subroutines contained in CAVITY_13M/PETSC_CPU/SRC should be copied into NEW_CAVITY_13M/PETSC_CPU/SRC and
-the subroutines contained in CAVITY_13M/PETSC_GPU/SRC should be copied into NEW_CAVITY_13M/PETSC_GPU/SRC.
-
-In each DATA subdirectory of NEW_CAVITY_13M/PETSC_CPU and NEW_CAVITY_13M/PETSC_GPU, the path
-to the mesh+partition has to be set as:
-
-cd DATA
-cp REFERENCE/cs_user_scripts.py .
-edit cs_user_scripts.py
-At line 138, change None to "../MESH/mesh_input_13M"
-At line 139, change None to "../MESH/partition_METIS_5.1.0"
-
-At this stage, everything is set to run both simulations, one for the CPU and the other one for the GPU.
