Class OptTreeConverter

java.lang.Object

org.apache.sysds.runtime.controlprogram.parfor.opt.OptTreeConverter

public class OptTreeConverter
extends Object

Converter for creating an internal plan representation for a given runtime program and to modify/create the runtime program according to the optimized plan. NOTE: currently only one abstract and one runtime plan at a time. This implies that only one parfor optimization can happen at a time.
