[mpich-discuss] Please Help Me! - Unable to register username/password with mpiexec on windows

[Jayesh Krishna]

Hi,
 You should find the source code for a sample MPI program, cpi, in the
examples directory of your MPICH2 installation (C version of cpi - icpi.c,
C++ version of cpi - cxxpi.cxx). The directory should also contain a
compiled version of cpi, cpi.exe (mpiexec -n 2 cpi.exe).
 Do you still get the error message when you run your MPI jobs? Are you
able to validate the username/password (mpiexec -validate) after
registering it (mpiexec -register)?
 
Regards,
Jayesh

Hi,
 Did you install MPICH2 as the administrator ? If so, did you specify that
MPICH2 is to be used by all users (The default is "Just me", you need to
select "Everyone" when installing MPICH2) ? Try re-installing MPICH2
making sure that you install MPICH2 for all users (Select "Everyone" when
prompted for while installing MPICH2).

(PS: Since the problem does not appear to be a bug we can discuss your
issue in the mpich-discuss mailing list. If we feel there is a bug in the
code we can re-open the ticket 717.)

Hi,

 EXCUSE ME! My English Is Very Low Level. EXCUSE ME!

I do this jobs that you said:

# Make sure you have the same user (reza) on both the machines and that
they have the same password (Assuming reza is not a domain user).
# Register your username/password using "-register" option of mpiexec
WITHOUT the "-user" option (mpiexec -register).
# Run your MPI jobs WITHOUT the "-user" option (mpiexec -n 2 cpi.exe)
# Use wmpiconfig if needed.

But it errored me!

Error is it " Credentials for reza rejected connecting to PC1
                 Aborting: Unable to connect to PC1 "

At first time I want to perform this statement "mpiexec -n 2 cpi.exe" it
errored!
But after I perform this statement "mpiexec -user 1 -n 2 cpi.exe"
                                    username:administrator
                                    password:administrator password.
the cpi is runing!

After Performing above statement I do this job:

I type this statement : "mpiexec -n 2 cpi.exe"
mpi not errored and running the cpi.exe!
