Ubuntu/16.04-OpenFOAM/README

+A few instruction for building an openfoam image to be used on the CFG platform.
+Openfoam in this image can be used directly, by calling the solver, or through a python procedure useful to monitor the calculation on the CFG platform.
+
+Usually I build a sandbox writable image. When it's ok, I build a read-only image to be uploaded on CFG platform.
+
+openfoamdev/ is the sandbox image, to be used for development and debug
+openfoam.simg is a non-writable image deployable on CFG platform
+
+
+BUILDING OF THE IMAGE
+
+To build the writable image, use the recipe-openfoam.txt recipe as follows
+
+   sudo singularity build -s openfoamdev recipe-openfoam.txt
+   
+Files in folders app and openfoam_hacks are needed with this recipe.
+In the app folders there are files needed for checking and monitoring the calculation.
+They can be modified or not added.
+Files in openfoam_hacks are needed to allows openfoam to run in the container.
+
+
+TESTING OF THE IMAGE
+
+To test the container, the two mountpoints requested by the CGF platform are to be creted.
+Of course they can reside in a folder different than ~.
+
+  mkdir ~/scratch
+  mkdir ~/service
+  
+- Serial test (direct call of the solver). Specify the solver and the case folder (-case option)
+
+  singularity -B ~/service:service ~/scratch:/scratch exec --cleanenv openfoamdev ###SOLVER###
+
+- Parallel test (direct call of the solver). Specify the solver, the case folder (-case option) and the number of processors.
+Of course, modify the system/decomposeParDict file accordingly.
+
+  singularity -B ~/service:service ~/scratch:/scratch exec --cleanenv openfoamdev decomposePar
+  mpirun -np ###PROCS#### singularity -B ~/service:service ~/scratch:/scratch exec --cleanenv openfoamdev ###SOLVER### -parallel
+
+NOTE When executing directly a solver in parallel mode, this can be a truly MPI calculation.
+     Instead, when testing the python procedure, only processors on one single node can be used.
+
+- Python procedure test.
+When using the python procedure, the solver, the case folder and the number of processors are specified on command line.
+The decomposePar utility is executed, then the solver is started through an mpirun command and the the check utility is started.
+As stated before, in this way only processors on a single node can be used. This will hopefully change in future.
+A webpage is displayed in "~/service/status.html". The abort button can't work locally, but only on the CFG platform.
+Anyway, the interrupt procedure is implemented. See /app/notification file.
+
+  singularity -B ~/service:service ~/scratch:/scratch --cleanenv exec openfoamdev /app/startup -s SOLVER -f FOLDER -p NUMBER_OF_PROCESSORS
+
+The /app/check file is to be modified in order to display the desided webpage.
+The parsing procedure is taylored for interFoam solver and can fail when parsing output of different solvers, so please modify it and test it locally.
+
+
+DEPLOYMENT ON CFG PLATFORM
+
+To build to a non writable image:
+   sudo singularity build openfoam.simg recipe-openfoam.txt
+
+The hpc_image script can be used to upload and register the new image on the CFG platform, 
+or to unregister and delete. Specify username, password and project in the script before using it.
+To upload and register 
+  
+  ./hpc_image upload openfoam.simg
+
+To unregister and delete
+
+  ./hpc_image delete openfoam.simg
+
+
+
