[mpich-discuss] problem about host node has multiple IP addresses

Dear developers/users: We try to specify the IP address in host file when start Hydra to run app: shell$ cat hosts 192.168.0.1 (host node IP) 192.168.1.1 The host node has multiple IP addresses. But it turns out the host node IP address who actually sends message isn't what we specified in the host file. How should we do to get the specified IP to send the message? Any help is highly appreciated :) Sincerely, Na Zhang
