[MPICH] smpd error message on windows - Do you have sufficient privileges ?

[Jayesh Krishna]

Hi,
 Is there any specific reason why you chose to register (mpiexe -register)
the service account ? The service account might not have enough privileges
for accessing registry entries since MPICH2 is installed for the individual
account. 
 Try registering (mpiexec -register) the individual account (used to install
MPICH2 package) for running the MPI jobs and let us know if you still get
the error messages.
 
Regards,
Jayesh

I checked the registry on the machine which shows this error message and
didn't see process entry under \software\mpich\smpd.
This is the case for all other machines used to run our MPI APP, but we
didn't experience the same problem on those machines.

The MPICH2 package is installed on each machine using individual account
which has local admin right and then we create a service account and use
mpiexec -register to register the service account on every machine for MPI
run. What could be wrong here on this machine?

Thanks
Richard

Hi,
 MPICH2 uses this (HKEY_LOCAL_MACHINE\Software\mpich\smpd\process\) registry
entry to store information (like the full path of the executable) pertaining
to an MPI process created by the PM/smpd.
 Check to see if you have sufficient privileges (to access registry entries)
on the machine where you are executing your MPI job.
 Since your program is executing correctly, the error could be during the
cleanup of the registry entries. Please look into the process registry
entries on the machine and let us know if it is clean.
 

1. Run "regedit.exe"
2. Check the values in HKEY_LOCAL_MACHINE\SOFTWARE\MPICH\SMPD\process  --
This should be clean (no entries) if there are no MPI processes running on
the system. (Also right-click on the process entry and you will know more
about the permissions allocated for the entry)
  
Regards,
Jayesh

Hi,

I saw the following error message when running our MPICH APP on windows.


"unable to open the HKEY_LOCAL_MACHINE\Software\mpich\smpd\process\3884
registry error 5 acces denied."


While I don't believe that our APP  is affected by the error
message(everything seems to be OK and we get the results we want),
I would like to make sure that nothing is going wrong. Does anyone have any
idea what that error message means and what its 
implications are ?

Thanks

Richard
