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?
