Hello all,<br><br>I am trying to run an MPI job beween two nodes using TCP/IP. The nodes consists of two different ethernet interfaces those are eth0 and ib0 (using ipoib)<br>I want to run my job through ib0 interface, host-names for both the interfaces are different node1 and node2 for eth0 and ibnode1 and ibnode2 for ib0, <br>
but when I run mpdboot by specifying ibnode1 and ibnode2 in the mdp.host file, mpdtrace shows<br>node1 and node2 still!<br>How can I select ib0 as communication interface?<br><br>-Devesh<br>
