Aahh, sure ... you are testing their rack mount stuff after a pop-out/pop in.  I see. Are we talking SDR or DDR Infiniband?  Do the systems have ConnectX technology?  I assume the bandwidth intensive stuff is much improved with Harpertown.  What about the version of MPI ... any changes to that.  Do you compare to Barcelona in fact or indirectly?  Clocks speeds equal?  Bios upgrades?
Maybe I will see you at SC07.
Thanks,

PS  How is it working with Maria M. ... ;-) ...??
