Thanks, that's a starting point! I looked at the two examples and conclude that the pattern for running a BSP job is creating a subclass of HamaCluster that initializes various stuff and then starts a number of BSP threads that do the actual work. Is that about right? It would seem to imply that a BSP job can only use one compute node, because each process is just a Java thread. On the other hand, it hardly makes sense to use Hadoop for just one node, so I wonder what I am missing here. Konrad.
