    Suppose smpd service doesnt launched on your second workstation. Check it.

    Oh, sorry.

    Try to launch this command from any other workstation (or from this workstation, it doesnt matter):

    telnet Sejnt-PC 49753

    Errors like "actively refused it" means that situation can have two reasons:

    1) Service is not running

    2) Service is not listening for needed ports

    From my experience of working with MPI first reason is the point.

    yes you are right.Could not open connection to the host on port 49753 Connect failed. How do i open this port ??I think that my network card doesn't properly.

    I think your network card state is not related to our situation.

    Try to launch smpd that is located in compute cluster pack folder or try to launch any other program. PingPong is not what you need for situation with one workstation IMHO.

    Hello,

    It looked like the firewall blocked SMPD from opening port on 49753. You may try the following command to see whether it helps:

    advfirewall firewall add rule name="MyRule" dir=in action=allow protocol=TCP localport=32000-65535

    Thanks,

    James
