[mpich-discuss] MPICH2 on Windows 7

[Jayesh Krishna]

 Do you have any firewalls (Windows firewall) running on the machine ? If you do, turn off the firewall and try re-running your code.
 What does "smpd -status" return ?

Regards,
Jayesh

Thanks a lot Jayesh! I unistalled MPICH2 and reinstalled it from the command line. I also ran wmpiregister from the command line (passed windows domain\username and password) and ran mpixec from the command line too (passed "behappy") at the command prompt but got the following error message. Any pointers will be very helpful!

C:\Program Files\MPICH2\bin>mpiexec.exe -n 1 C:\Dev-Cpp\Projects\FirstShot\First_Shot.exe

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!
