Seems to me that your "DOS" could equally be a description of SUNMOS
(http://en.wikipedia.org/wiki/SUNMOS) and its descendants, which
(AFAIK) are still in use at Sandia running significantly large
clusters solving production problems.
Indeed Cray's Unicos/ic (the node os in the XT machines) describes in
a similar way, and may even be the latest Sunmos descendant, if not
it's certainly philosophically close.
So the answer to your question is likely "Quite a lot of people".
(Or, maybe, a few people, but they have a *lot* with a lot of nodes :-))
