Hi,
 Please uninstall your existing version of MPICH2 and install it following the instructions in Section 9.4 (NOT Section 9.1) of the Installer's guide (available at http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs). The error messages that you see is because MPICH2 was not installed correctly in the system (a known bug with Win7/Vista).

Regards,
Jayesh

Hello 
Trying to setup MPICH2 to run on a single Windows 7 Professional multprocessor machine to execute MCNP5. Install of the windows binary seemed to go correctly. 




Tried to set a user account in 

wmpiregister.exe 

Seemed to accomplish the task. 

Tried to set things for a single machine in 

wmpiconfig.exe 

Get message 

Error: No smpd passphrase specified through the registry or .smpd file exiting 

I had a passphrase entered during the install of MPICH2. Created a .smpd file with that passphrase. File doesn’t seem to be compatible with Windows 7. I can see it from CYGWIN but not from Explorer. 

Looked at 

wmpiexec.exe 

I don’t see any way to pass command line arguments to the program being executed. Typical usage 

\MCNP\mcnp5\bin\windows\mcnp5mpi.exe i= \rm3\155-1600c.m 

Where the input file path for the program is passed on the command line. Additional parameters are for output file names, neutron source files and others. 

Trying from a command window. 

C:\Program Files\MPICH2\bin>smpd.exe -start 

OpenSCManager failed: 

Access is denied. (error 5) 



On the off chance, tried the command line for execution. 

C:\Program Files\MPICH2\bin>mpiexec -n 7 \mcnp\mcnp5\windows\mcnp5mpi.exe i= \rm3\155-1600c.m 

Please specify an authentication passphrase for smpd: 

Error while connecting to host, No connection could be made because the target machine actively refused it. (10061) 

Connect on sock (host=localhost, port=8676) failed, exhaused all end points 

Unable to connect to 'localhost:8676', 

sock error: Error = -1 

Just for grins 

C:\Program Files\MPICH2\bin>smpd.exe -stop 

OpenSCManager failed: 

Access is denied. (error 5) 



Local IT is no help for anything outside of the standard desktop program set.
