Thanks for your reply, Steven. I tried to use the absolute path of mpirun, but the problem was still there. I indeed did the mpi install several times and i'm not sure whether i have uninstalled the old one. Is there any method to list out all the mpi I have installed? _______________________________________________ meep-discuss mailing list [email protected] http://ab-initio.mit.edu/cgi-bin/mailman/listinfo/meep-discuss
