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 :-))
