For part of my dissertation, I am running csound on a cluster. 
Nothing so generic as splitting scores, following dependencies, 
etc., nor as low-level as incorporating Message Passing via the 
Csound API.

As your question implies, and Steven, Victor and Oeyvind  confirm, 
that's not easy.

My approach has been to use php to massage the data into .orc and 
.sco files. I also use php to automate (as much as possible) the 
distribution via PBS.

Turns out that's not easy either (at least not with the amount of 
data I'm working with).

In addition to the articles Steven cites (though not strictly 
Csound), there's this project (which I believe dates back to the 
mid-90's):

http://ems.music.uiuc.edu/people/tipei/Diass/index.html

If anyone knows of anything else, I'd love to know about it.

Cheers,
Brian
