Sorry, I should be more clear. The system has 3 servers which are HP xw8600 workstations (<a href="http://h20331.www2.hp.com/Hpsub/downloads/xw8600_xw6600_FAQ_hi_res.pdf" target="_blank">http://h20331.www2.hp.com/Hpsub/downloads/xw8600_xw6600_FAQ_hi_res.pdf</a>). Each of them has 1 gpu (nvidia quadro fx 5600 with 2 dvi connectors). There is only one cluster. Sorry about the confusion.<div>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Sorry, but I'm confused by the question.<br>
<br>
You say you have a display comprising 6 screens. Your rendering cluster<br>
has 3 nodes each with 1 GPU. How do you get a signal to all 6 screens<br>
with only 3 GPU's? Does each GPU have a dual output that can drive two<br>
screens? If so, are the two screens treated as one so that one window<br>
from one MPI process covers both, or do you have to run two MPI processes<br>
per GPU node to drive both screens?<br>
<br>
You also say that you have nodes with only CPU's in them. How many do you<br>
have? And how are they connected to the GPU nodes? Are they two totally<br>
separate clusters or all they all part of the same cluster and the GPU<br>
nodes are just three special nodes in a larger cluster?<br>
