<br>We brought it up with our admins onsite, and they dont' think that setting up NAT would be any big problem, so they're looking into it now. What we want to do is use the IceTDesktop render mode to parallel process across our 12 nodes with the display piped to a client (probably windows) that's not part of the cluster. It was my understanding (and experience) that in this setup (mpirun -np 12 pvserver -rc) that each pvserver process will want an independent connection to the Client, which would require full network connectivity if it's any host other than the head node.

Hello,<br><br>Actually, as far as I remember there is no need for connectivity from<br>satellite nodes. I am pretty sure Randal's setup does not use NAT, so<br>there is no way his satellite nodes can access Internet. Randal, this is
<br>the tile cluster?<br><br>But, again, I see no reason for satellite nodes to access client. They<br>will try to access render server nodes if you do render/data server<br>separation.<br><br> Andy<br><br>Wylie, Brian wrote:
