[mpich-discuss] MPICH2 on Windows 7

[Jayesh Krishna]

Hi,
 You should register a valid Windows username and password with mpiexec (mpiexec -register OR wmpiregister) . The "behappy" passphrase should be specified during the installation process (by default it is specified for you).
 This could be an issue with the MPICH2 installation on Windows 7. I would recommend following the instructions in Section 9.4 of the Installer's guide (available at http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs -- don't follow instructions in Section 9.1) to install MPICH2.
 Let us know if it works.

Regards,
Jayesh

Hi Jayesh, 

I got your email id while browsing through the following discussion list: 

http://lists.mcs.anl.gov/pipermail/mpich-discuss/2010-February/006529.html 


I am trying to run MPICH2 from the Windows 7 environment but I can't get the wmpiexec.exe working and get the following error message: 


Error: No smpd passphrase specified through the registry or .smpd file, exiting. 

I did the installation as per the instructions on the folowing link but I am not sure what info I should provide for account name and password when I run wmpiregister.exe. I tried several combinations of account name and password (admin account name from which I installed/my login account name and "behappy" password and the passwords associated with the account names.

Any pointers will be appreciated! 

Thanks & Regards!
