BottomUp2 evaluator

 

This evaluator is the fastest bottom-up evaluator which is available in OntoBroker. It is

Very memory efficient
Highly efficent on multicore/multi CPU systems (it provides in-kernel parallelization)

BottomUp2 is able to execute multiple join operations at the same time. BottomUp2 is the recommended bottom-up evaluator for the inference server.  In order to start OntoBroker with this evaluator set

BottomUpEvaluator=BottomUp2

in OntoConfig.prp. In most cases it is sufficient just to select "auto" (then the number of parallel reasoning threads is automatically adapted to the available number of CPUs).
