[mpich-discuss] [mpich2-dev] I can not make MPI recognizes a dual core

Tue May 25 15:10:40 CDT 2010

Hi,
I reinstalled MPICH and I does not modified the default SMPD
passphrase provided in the user input textbox, it is behappy.
After the installation I try to run a non-MPI program (mpiexec -n 2
hostname) and I have the same error:
I have the output:
Please specify an authentication passphrase for smpd: I write behappy
The system response to me:
Aborting: unable to connect to User-PC
Very thanks.
I will thanks any help.

>> Hi,
>>  The error message shows that you did not specify an authentication passphrase for SMPD. If the installation process was successful you should not be seeing this message.
>>  During the installation process, the MPICH2 installer requests for the SMPD passphrase. A default SMPD passphrase is provided in the user input textbox for convenience. Did you delete/remove the default passphrase during the installation step ?
>>  Can you reply with details the steps used to install MPICH2 (You can add inputs to the installation steps that I provided in my previous email)? Also specify, in detail, if you modified any default input values during the installation process.

>>> Hi,
>>>  I would recommend uninstalling MPICH2 and installing it again from the administrator command prompt by following the steps below.

>>> # Download the latest version of MPICH2 (http://www.mcs.anl.gov/research/projects/mpich2/downloads/index.php?s=downloads).
>>> # Open an administrator command prompt (Right-click on the command prompt icon and select "Run as administrator")
>>> # From the admin command prompt use the msiexec utility to uninstall MPICH2 (eg: Type "msiexec /x mpich2-1.2.1p1-win-ia32.msi" to uninstall MPICH2 using the mpich2-1.2.1p1-win-ia32.msi installer)
>>> # The above command will bring up the Installer GUI to uninstall MPICH2. Follow the steps to uninstall MPICH2.
>>> # From the admin command prompt use the msiexec utility to install MPICH2 (eg: Type "msiexec /i mpich2-1.2.1p1-win-ia32.msi" to install MPICH2 using the mpich2-1.2.1p1-win-ia32.msi installer)
>>> # The above command will bring up the Installer GUI to install MPICH2. Follow the installer steps to install MPICH2.
>>> # After the installation try to run a non-MPI program (mpiexec -n 2 hostname) . If the job launcher, mpiexec, requests for a username/password please provide the same (When specifying the username/password make sure that you specify the domain name if the user is a domain user).
