Having Trouble Running MPICH in Windows

[bayram_aygun]

Here is what I've done:

1) I installed "MPICH2" in the default location which is "C:\Program Files\MPICH2".

2) On the tasklist in my DOS Shell I see "smpd.exe", "smss.exe". Does that mean
the spmd service is running? If I write "smpd -start" in dos shell I get the following message: "An instance of the service is already running. (error 1056)". I guess that's a good sign, right?

3) I registered using my username and my password which is also the passphrase. That's OK right?

4) Setting Up Path Variable is done. I did it for all Users (System Variables). When I write "echo %PATH%" I get the following message:

U:\>echo %PATH%
C:\ProgramFiles\Tcl\bin;C:\WINDOWS\system32;C:\WINDOWS;C:\WINDOWS\system32\wbem;
c:\program files\ati technologies\ati control panel;C:\Program Files\MATLAB\R200
7a\bin;C:\Program Files\MATLAB\R2007a\bin\win32;C:\Program Files\SSH Communicati
ons Security\SSH Secure Shell;C:\Modeltech_6.1\win32


5) Finally, when I want to run a code via OpenSeesSP I get the following error:

U:\>mpiexec -np 2 OpenSeesSP Bayram_MSCS_WithActualandPseudoPiles_3D_fromScratch
.tcl
Aborting: unable to connect to bayrampc.ad.rice.edu, smpd version mismatch.

Do you have any idea what I might have done wrong?

Thanks,

Check your path enviroment setting, please.

Make sure the "X:\MPICH2\bin" is in front of the Matlab Path.

Since the Matlab also have an "mpiexec" command in their Path, which caused the "smpd version mismatch"...


Best regards,

Hi,

I saw your reply on OpenSees forum. I thank you for that. I followed your advice
and did the following:

1) I put MPICH2 in C: folder ==> C:\MPICH2

2) MATLAB also has mpiexec.exe . I deleted Matlab's mpiexec.exe and pasted the
one I'm using for OpenSees. So I get rid of the smpd mismatch error

3) The next error I get is this :

C:\>mpiexec -np 2 OpenSeesSP Bridge.tcl

"Credentials for ba2 rejected connecting to bayrampc.ad.rice.edu
Aborting: Unable to connect to bayrampc.ad.rice.edu"

I checked from Control Panel-->User Accounts that I belong to Administrators
Group, so I'm puzzled. Do you have any idea what might be the problem?

Thanks for your time. I realize it's valuable.
