<P><FONT SIZE=2> Hi,<BR>
Can you send us the debug output of mpiexec and smpd ? Please follow the instructions below to send us the debug output,<BR>
<BR>
# Stop any instances of smpd using the command, smpd -stop<BR>
# Start smpd in the debug mode using the command, smpd -d<BR>
# 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<BR>
<BR>
# 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<BR>
<BR>
# Send us the debug/verbose outputs of mpiexec and smpd.<BR>
<BR>
Let us know the results.<BR>
<BR>
Regards,<BR>
Jayesh<BR>

Hi,<BR>
