the blade chassis infrastructure is expensive.  for supercomputing, the 
cheap cloud tray computers are probably much more cost effective.    
bunches of folks, HP and Dell included, are making server trays that 
have 2 or more complete nodes per 2U chassis, much cheaper than 
traditional blades, like the Dell C microservers.

I *am* kind of surprised at the 64 core per node thing, single large 
nodes like that are more typically used as enterprise database servers 
where you have 100s/1000s of clients doing SQL queries concurrently...   
What the geophysicists at my son's U are using for seismic processing 
and such are racks of 2 socket machines with a pair of NVidia Cuda 
processors each to do the numeric heavy lifting.

if those 64 processor servers are like $14000 or whatever, I think I'd 
buy 18 of these instead :D

(ok, that particular chassis is setup as a storage server, with 14 drive 
bays on a raid card, but you can find lots of similar things in various 
configurations)
