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

[Jayesh Krishna]

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.)

Regards,
Jayesh

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!
