NEMO/README.md

+Description:
+============
+
+Presentation
+------------
+
+This template is just here to show the way that we should present the README for a given application. 
+
+Here I describe that this template is not performing any scientific simulation, and uses no specific library.
+
+Technical information:
+----------------------
+
+* website : http://this.url.doesnot.work 
+* Scientific domain : none 
+* Language : C/C++/Fortran/Python
+* Parallelism : MPI + OpenMP
+* GPU acceleration : Yes (CUDA) 
+* Scalability : high
+* Vectorization: poor
+
+
+Compilation and simulation:
+===========================
+
+Here we describe the different phases from the download to the validation of the simulation.
+
+Download:
+---------
+
+Information (if needed) about how to get the sources.
+
+For instance:
+```
+./download.sh
+```
+
+Compile:
+--------
+
+Information (if needed) about how to compile the application. 
+
+For instance:
+
+Compile the code using:
+```
+source machines/occigen-bdw/env
+./compile.sh
+```
+
+`machines/occigen-bdw/env` contains the information for compilation (module load gcc openmpi lapack hdf5 ...)
+
+Run and validate the simulation:
+--------------------------------
+
+For each test case, given in a separate folder (e.g. testcase_small), you can find three scripts:
+
+*  prepare.sh: prepare the simulation (move data to the right location, recompile some minor changes, ...)
+*  run.sh : run the application and print out the evaluated metric
+*  validate.sh: validation of the simulation on a scientific point of view
+
+For running and validating the simulation, one should be able to do:
+```
+cd testcase_XXX
+./prepare.sh
+./run.sh
+./validate.sh
+```
+And getting no error code returned.
+Those steps can also be used in a batch file for running the simulation using a job scheduler.
+

NEMO/compile.sh

+# XIOS Compilation
+xios-2.5 directory must be a sub-directory of NEMO/release-4.0
+# 1. Prepare an arch file for the target machine 
+./make_xios --arch X64_IRENE -j 8
+#NEMO
+#creation fichier arch-irene.fcm
+# lancement de la compilation pour BENCH
+  ./makenemo -m irene -a BENCH -v3
+#
+# Find the produced exec

+# find . -name nemo.exe

NEMO/testcase_small/README.md

+Test case presentation
+======================
+
+The small test case of the template application is doing nothing but watching videos on Youtube all day long.
+It uses no DFT method, nor spectral method or anything else. The FFTW is widely not use for this case.
+
+
+Case profile
+------------
+
+A profiling of a small specfem3D test case performed on Occigen on 1 haswell node (64GB) is available in this folder:
+`profile_occigen-hsw.html"
+
+It has been generated using Intel APS (infos: https://software.intel.com/sites/products/snapshots/application-snapshot/)
