We are interested here in the first step of the parallelization of an OpenFoam simulation, which consists in using several cores on a single processor. For this purpose, OpenFoam does not use OpenMP (although dedicated to multi-core) but indeed MPI (as for the multi-processor parallelization of a cluster).

Automating the deployment of calculations on a platform such as AWS is an important issue in order to increase the productivity of Computational Fluid Dynamics (CFD) studies. Indeed a company should charge for the time spent developing the model and not not while performing command line sessions, which are difficult to remember when they are not practiced on a daily basis.
