I was trying to run a chapel program on two locales which are Linux systems. The below error was shown to me. I am using gasnet with udp conduit and ssh. I have installed gasnet without errors and I can do ssh from one machine to the other machine. I simply don't have any idea what this error means. Regarding udp, I am not sure if I need to do TCP to UDP forward on my machines or not? (I have not done it). In addition, my LAN system has no internet connection. Thanks in advance for any help.
