Use hydra instead of MPD: http://wiki.mpich.org/mpich/index.php/FAQ#Q:_I_don.27t_like_.3CWHATEVER.3E_a... -Dave On Jan 11, 2013, at 12:55 PM CST, Na Zhang wrote:

Dear developers,

We want to start MPD daemons on 2 different subnets: for example, subnet #1 192.168.0.0/24 and subnet #2: 192.168.1.0/24

The two subnets are connected via switches and they can talk to each other. Next, we'd start MPD daemons on two nodes:

Node #1 (in subnet #1): (hostname:node_001) IP=192.168.0.1 Node #2 (in subnet #2): (hostname:node_002) IP=192.168.1.1

We used the following commands:

on Node #1: mpd --ifhn=192.168.0.1 --daemon (daemon is successfully started on node_001)

on Node #2: mpd -h node_001 -p <node1's_port_number> --ifhn=192.168.1.1 --daemon (daemon cannot be started on Node #2. there is no error message, we use "mpdtrace" to check on Node #1, it shows no daemon started on Node #2 )

Node #2 cannot join the ring that is generated by node #1.

How should we do?

Thank you in advance.

Sincerely, Na Zhang
