Hi,
 Great, let us know if you have any further issues.

(PS: Yeah, I meant ignore the message from wmpiconfig.)
Regards,
Jayesh

	Hi Jayesh ~

	Sorry - perhaps I wasn't clear: everything was working through wmpiexec but not working on the command line (behaved like MPICH2 was installed but services were not running). (You may have meant ignore the error message from wmpiconfig below.) However, after closing my command prompts and reopening them (after the successful test through wmpiexec) they now seem to behave perfectly. I can't say I have a good explanation for this but I am glad everything is operational. I will chime in again if I have any more difficulty. 

	Thanks for all the help,
	~Mike C.

Hi,
 Ignore the error message from wmpiexec. There is a known bug that causes it to report inaccurate status (does not work as expected).
 Can you run an MPI job from the command line?

Regards,
Jayesh

	The instructions referenced below were followed to install MPICH2 on the Windows 7 system (uninstalled / reinstalled twice with the same results). Is there any reason the wmpiexec and command line behavior would be different? Perhaps some system-wide post-install setting?

	Thanks,
	~Mike C.

Hi,
 The earlier error message (smpd error message) indicates that MPICH2 was not installed correctly on your system. I would recommend the following,

# Uninstall MPICH2 from the system
# Follow instructions in Section 9.4 (NOT 9.1) of the MPICH2 installer's guide (available at http://www.mcs.anl.gov/research/projects/mpich2/documentation/index.php?s=docs) to install MPICH2.

Regards,
Jayesh

Follow up: I can run the example successfully through the GUI wrapper (wmpiexec.exe) but not from the command line through a console, which seems odd. So the installation works and the relevant service must be running but it doesn’t seem the command line environment can communicate with it. Besides setting the path, is there anything else I can do on this front? 



Thanks,

Trying to run the cxxpi.exe example program and I'm hitting a roadblock (seems others have shared this as well) on a Windows 7 x64 system. I have followed the instructions summarized in: http://lists.mcs.anl.gov/pipermail/mpich-discuss/2011-April/009694.html . Checking services, the "MPICH2 Process Manager" is started (I restarted it to confirm). However, checking the status of SMPD: 



>smpd -status 

no smpd running on mike-studio17 



Trying to run a test produces the error in the thread above: 



>mpiexec -n 2 hostname 

Error while connecting to host, No connection could be made because the target machine actively refused it. (10061) 

Connect on sock (host=mike-studio17, port=8678) failed, exhausted all end points 

Unable to connect to 'mike-studio17:8678', 

sock error: Error = -1 



In the menu of wmpiconfig.exe under "error" it says " mike-studio17: MPICH2 not installed or unable to query the host ". I didn’t install to the default path, but other than that there is nothing extraordinary (bin directory added to path of course). If I scan hosts for versions, the wmpiconfig tool does detect the correct version on this host. Using “scan hosts”, I get “ Error: No servers available for this domain ”. It seems like the service simultaneously is and is not running. Anything I can do to debug? 



Thanks, 

~Mike C.
