_______________________________________________Hello Ralph,Your suggestion did the trick.>> I don't remember back to 1.4.3, but I think it was true even that long ago - we provide an environmental variable OMPI_COMM_WORLD_RANK that holds the rank of the process.Out of curiosity if I want to learn more about this topic in detail what would be a good place to start.
Thank You for your help.Regards,Deepak
