Hi, I have built mpich-master-v3.2-331-g44fd9c5f39e5 on my machines (Solaris 10 Sparc, Solaris 10 x86_64, and openSUSE Linux 12.1 x86_64) with gcc-5.1.0 and Sun C 5.13. Unfortunately I get an error if I try to specify different host lists for the master and slave program. linpc1 hello_2 116 mpiexec -np 1 --host sunpc1 hello_2_mpi : -np 2 --host sunpc1,linpc1 hello_2_slave_mpi [mpiexec@linpc1] hostlist_fn (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/ui/mpich/utils.c:373): duplicate host file or host list setting [mpiexec@linpc1] match_arg (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/utils/args/args.c:152): match handler returned error [mpiexec@linpc1] HYDU_parse_array (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/utils/args/args.c:174): argument matching returned error [mpiexec@linpc1] parse_args (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/ui/mpich/utils.c:1597): error parsing input array [mpiexec@linpc1] HYD_uii_mpx_get_parameters (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/ui/mpich/utils.c:1649): unable to parse user arguments [mpiexec@linpc1] main (../../../../mpich-master-v3.2-331-g44fd9c5f39e5/src/pm/hydra/ui/mpich/mpiexec.c:149): error parsing parameters linpc1 hello_2 117 I would be grateful if somebody can fix the problem. Please let me know, if you need more information. Thank you very much for any help in advance.
