Cool Doug!
So are your numbers consistent with:
A 2 socket, 8 core Linpack number of about ~77 GFLOPs
Stream Triad for the same 2 socket board of ~8.6 GBytes/sec.
Are the numbers you are reporting from Appro Dual Socket Blades?  I did not think they had announced Harpertown Blades yet.  As I recall the Tri-Labs win was for Dual Socket Barcelona's and there Intel blades solution was Clovertown.   Can you clarify without violating an embargo ... ;-) ...
