The problem was that orted couldn't find ssh nor rsh on that machine. I've added my installation to PATH and it now works. So one question: I will definitely not use MPI_Comm_spawn or any related stuff. Do I need this ssh? If not, is there any way to say orted that it shouldn't be looking for ssh because it won't need it?
