Hi there,

I've have no experience with mahout but I know that it will solve my
problem :) !

I've the following requirements:

 * No hadoop setup should be necessary. I want a simple approach and I
know this is possible with mahout!
 * I have lots of points (~100 million) but also some RAM (32GB)
 * I know the clusters upfront via its center positions.
 * I need to assign every point to exactly one cluster.
 * Every cluster can have a different shape, area size and point count

I've found:
http://en.wikipedia.org/wiki/OPTICS_algorithm
http://en.wikipedia.org/wiki/DBSCAN

Both algorithms do not really pay attention to the fixed cluster center
but I think I will start there. Is one of them implemented in mahout?

Or do you have another idea or hint/link?

Regards,
Peter.
