Gearman     Gearman provides a generic framework to farm out work to other machines or dispatch function calls to machines that are better suited to do the work. It allows you to do work in parallel, to load balance processing, and to call functions between languages. It can be used in a variety of applications, from high-availability web sites to the transport for database replication. In other words, it is the nervous system for how distributed processing communicates.     http://www.gearman.org/doku.php     tags: cluster scipy-cluster - Google Code     is library provides Python functions for agglomerative clustering. Its features include * generating hierarchical clusters from distance matrices * computing distance matrices from observation vectors * computing statistics on clusters * cutting linkages to generate flat clusters * and visualizing clusters with dendrograms.     http://code.google.com/p/scipy-cluster/     tags: cluster hac python
