<BR><FONT SIZE=2>> Also, as far as I know, no one outside of Mellanox has looked at this.</FONT>
<BR><FONT SIZE=2>> So that would be a next step.</FONT>
<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Is there any documentation on IBDM ?</FONT>
<BR><FONT SIZE=2>[EZ] Not much. The attached tar file holds:</FONT>
<BR><FONT SIZE=2>IBDM Overview - a diagram showing IBDM objects and their relations (maybe I should UML this one day).</FONT>
<BR><FONT SIZE=2>Ibdm_wrap.html - the TCL API to the IBDM utilities and datamodel</FONT>
<BR><FONT SIZE=2>IBNL Specification - describing the format for defining arbitrary systems IB netlist</FONT>
<BR><FONT SIZE=2>MTS14400-48.ibnl - example IBNL for 144 ports switch.</FONT>
</P>
<P><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> Also, are there updates to this or is the version in the tree what</FONT>
<BR><FONT SIZE=2>> should be looked at (and commented on) ?</FONT>

<BR><FONT SIZE=2>> </FONT>
<BR><FONT SIZE=2>> By using the comment fields appropriately with semantics for logical</FONT>
<BR><FONT SIZE=2>> hierarchy.</FONT>
<BR><FONT SIZE=2>[EZ] So the user is supposed to annotate the entire cluster at the node level with hierarchy names? Is there a tool to create these netlists?</FONT></P>

<BR><FONT SIZE=2>> Yes.</FONT>
<BR><FONT SIZE=2>[EZ] Can you provide an example system definition file?</FONT>
