SiCortex != blades.  And != beowulf in the sense of "commodity" hardware 
implementations, although the guts of a blade might make that argument.

SiCortex is not too far from the Beowulf concept but is possibly closer 
to a packaged single DM entity.  I'd thought of it as a low-power, low 
heat (DM) HPC system without ever considering the beowulfness of it.  It 
uses Linux and MPI, so it meets my needs in that regard.  It's low-power 
and thus lower heat; these are good.  It's slower than current PC class 
hardware.  Bad selection for me at this point.
