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


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).
