Hi,
I have solved the credentials issue. Now I have registered an Admin
account following the steps you proposed and seems to be solved.
The executalbles seems to start as expected! The only problem is that they are
trying to read files from \Program Files\MPICH2\bin\ folder instead from
corresponding folders D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster\,
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1\ .... etc
Just need to make the four executables to read data from different folders
(exactly where the executables are located)
See atteched error. The mpi2.bat didn´t changed.
Thanks for your help.
Horacio.

Hi,
Try registering a valid Windows username/password with mpiexec by following the
steps below,
# Delete the default username registered by typing "mpiexec -remove" at the
command prompt
# Register a valid Windows username/password by typing "mpiexec -register" at
the command prompt
# Validate that the registered username/password by typing "mpiexec -validate"
at the command prompt
# If the validation is successful try running a simple non-MPI program, mpiexec
-n 2 hostname
# If the above steps are successful try running your batch file.
(PS: I still recommend providing the full path to the mpiexec executable in your
batch file until to finish sorting out issues with the setup)
Regards,
Jayesh

Hi Jayesh,
This time it seems it´s going to work. I have modified the "mpi2.bat" file, now
it is:
C:
cd \Program Files\MPICH2\bin\
mpiexec -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster2\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster3\Prueba32-01
Now the system is asking for user credentials. But when I enter
"computer-name\User" and my windows account password, it didn´t accept it.
Do you know what credentials is this referring to? (Please see the attached
image)
Horacio.
PS: I asume if I add \Program Files\MPICH2\bin\ to my path environmental
variable this should work without need to go to this directory to run the
mpiexec.

Hi,
AFAIK, MPICH and MPICH2 can be installed on the same machine (Although we don't
test that setup routinely in our lab). We currently do not support installing
two versions of MPICH2 on the same machine.
Try specifying the complete path to mpiexec (C:\Progra~1\MPICH2\bin\mpiexec -n 1
...). Let us know if it works.
Regards,
Jayesh

Hi Jayesh,
Thanks for your answer.
I followed your suggestion by creating a bat file that executes the command you
sent to me.
The content of the bat file is:
D:
cd \HORACIO\DOCTORADO\2-Corridas\MPI\Cluster
mpiexec -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster2\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster3\Prueba32-01
The answer is:
Aborting, unable to connect to Usuario-PC, smpd version mismatch
¿How can be problems with smpd version if this is only one machine with four
cores? There is no way to have different versions of MPICH2 installed.
Note: In addition to have MPICH2 installed I also have MPICH installed into the
same computer.
Thank you.
Horacio.

Hi,
You should be able to launch different executables as part of the same job by
separating the executables (and the executable specific args) by a colon (:).
Try the following command and let us know if it works for you.
mpiexec -n 1 D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster2\Prueba32-01 : -n 1
D:\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster3\Prueba32-01
Regards,
Jayesh

Hello,
I got this e-mail from the mpich_discuss forum. I have already suscribed to it.
I have a code paralellized that is runnig OK when I compile it using Win32 Intel
Fortran compiler and MPICH1 libraries.
When I compile it using EMT64 Intel Fortran compiler and MPICH2 libraries it is
compiled OK but I can´t make it run.
I need to run this on a single Windows 7 machine using its four cores (Intel
i7). Once the core is finished I will run it on a 20 node cluster. Now my
problem is to run on a single machine.
When running the win32 MPICH1 compiled executable there is no problem at all.
I´m using four different folders and executing four executables. The executables
are the same, but the information they use is readed from different folders. For
this, I´m setting the enviromental varibles manually, and runing the executable
"Prueba32-01.exe" on four cores as follows:
file "mpi.bat" on folder \HORACIO\DOCTORADO\2-Corridas\MPI\Cluster:
D:
cd
\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster
set MPICH_JOBID=ns.123
set MPICH_IPROC= 0
set MPICH_NPROC= 4
set MPICH_ROOT=Usuario-PC:1
Prueba32-01
file "mpi.bat" on folder \HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1:
D:
cd
\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster1
set MPICH_JOBID=ns.123
set MPICH_IPROC= 1
set MPICH_NPROC= 4
set MPICH_ROOT=Usuario-PC:1
Prueba32-01
file "mpi.bat" on folder \HORACIO\DOCTORADO\2-Corridas\MPI\Cluster2:
D:
cd
\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster2
set MPICH_JOBID=ns.123
set MPICH_IPROC= 2
set MPICH_NPROC= 4
set MPICH_ROOT=Usuario-PC:1
Prueba32-01
file "mpi.bat" on folder \HORACIO\DOCTORADO\2-Corridas\MPI\Cluster3:
D:
cd
\HORACIO\DOCTORADO\2-Corridas\MPI\Cluster3
set MPICH_JOBID=ns.123
set MPICH_IPROC= 3
set MPICH_NPROC= 4
set MPICH_ROOT=Usuario-PC:1
Prueba32-01
This works fine with MPICH1. I couldn´t find a way to launch this executable on
four different folders using mpiexec or even manually by setting the
environmental variables "PMI_RANK" and "PMI_SIZE"
Could you please help me?
Thank you in advance.
Horacio.
