George, Yes, this is an option, create my own type library, but i need do a cover of MPI_Send, MPI_Receive, ... and other things . So was searching for an OpenMPI way, instead of doing it myself.
I'll try the option that mention Gilles Gouaillardet: i will build OpenMPI 4.0.1 with --enable-heterogeneous. Thank you very much for your help. Regards, Sergio.
