[mpich-discuss] mpiexec / Windows networking

[Michael Colonno]

            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,

            ~Mike C.

            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.
