I installed MSMPI from the Windows Server 2008 R2 SP4 installation package on Windows 10 Professional and ran mpipingpong with smpd running in the background (SDK mode), everything looks fine. Could you please answer the following questions so that we can
dig deeper on your issue?
1. What's the exact version of your HPC Pack?
2. Are you launching your program via HPC Pack job submit or are you running mpiexec directly with smpd running in the background (SDK mode)?
3. Can you share the test program? Is the source code available?
4. Can you share the exact command line you used to submit the job or run mpiexec?
5. Can you share the output of your run? What's the MPI error?
Thanks,
Jeff
