MPICH2: Failed to register smpd's Service Principal Name with Domain Controller

Learning MPI (MPIPICH2). When I gave the following command 

C:\Program Files\MPICH2\examples>smpd -register_spn

I get the error: 

[-1:5440]...ERROR:GetComputerObjectName() failed (1351)Configuration information
 could not be read from the domain con
Failed to register smpd's Service Principal Name with Domain Controller

How do I remove this error? And what exactly is the meaning of the reported error. This might help me in solving this.

Solution

  • Which version of MPICH are you using? Anything after 1.4.1p probably doesn't run on Windows and even the versions before that are unsupported now. You might try some of the alternatives on the MPICH website.
