[mpich-discuss] SMPD, Problem launching when using -host

[Jayesh Krishna]

 Hi,
  Can you send us the debug output of mpiexec and smpd ? Please follow the
instructions below to send us the debug output,

# Stop any instances of smpd using the command, smpd -stop
# Start smpd in the debug mode using the command, smpd -d
# Run a non-MPI program with mpiexec in the verbose mode using the
command, mpiexec -verbose -n 1 hostname : -host IPADDRESS_OF_roobarb -n 1
hostname

# Run an MPI program (cpi.exe provided with MPICH2) with mpiexec in the
verbose mode using the command, mpiexec -verbose -n 1 cpi.exe : -host
IPADDRESS_OF_roobarb -n 1 cpi.exe

# Send us the debug/verbose outputs of mpiexec and smpd.

  Let us know the results.

Regards,
Jayesh

Hi,

     No I get the same error if I use the ipaddress.
