Thank you a lot for this overview!

Concerning the parallelisation of K-means: It seems to be difficult to 
choose a size for the pieces of points. Since the 'combine' function is 
associative something map-reduce-like seems to be applicable. That is, if 
there is a library function for a parallelised 'reduce' and I promise, 
that I call it with an associative function as argument, then the library 
could choose an appropriate size for the pieces. Is there already library 
support for parallelism of this style?
