Hmmm... my impression was/is severe issues in execution.  The technology 
is there, it seems that some in AMD (not the folks at the show) just 
"don't get it"(TM).  I am guessing they think HPC is a small niche 
market which is not important to them.

This is a shame, as they do have very good technology that, if they can 
just deliver it, would be quite competitive and leading in a number of ways.

I am not sure about this.  Have some tests to do.  Bug Doug Eadline on 
this, he has some good early impressions based upon his testing.

A little extreme I think.

Some of us doubt there ever will be any benefit from this merger.

I saw the Mellanox 10GbE units, Myricom's stuff,  the Arastra (sp?) 
switches, Woven systems stuff.  For 10GbE to be meaningful, it has to be 
port cost competitive with IB.  Three of the vendors above grasped that. 
  There were a number of vendors that (mistakenly) believe that $2k 
USD/port is a good thing in clusters and storage systems.  I wish them 
luck with that.  Myricom's stuff is pretty neat, well priced.  They have 
some interesting ideas.
