[Beowulf] multi-threading vs. MPI

Distributed objects... Corba... Soap... This all precedes multiple cores per server and essentially is message passing in the enterprise.

Many on this list suggest that using multiple MPI-processes on one and 
the same node is superior to MT approaches IIUC. However I have the 
impression that almost the whole industry is looking into MT to benefit 
from multi-core without even considering message-passing. Why is that so?
