Hi,rnrnI solved my problem using this tutorial:rnrnhttp://software.intel.com/en-us/articles/performance-tools-for-software-developers-building-open-mpi-with-the-intel-compilers/rnrnI just compiled the OpenMPI (in my case with the intel compilers) and after all used the MPI option in OpenLB makefile, changed the CXX to the MPI wrapper mpiCC).rnrnSorry about this thread.rnrnThanks,rnHenrique.
