Class QuaternaryOp

  • All Implemented Interfaces:
    ParseInfo

    public class QuaternaryOp
    extends MultiThreadedHop
    Note: this hop should be called AggQuaternaryOp in consistency with AggUnaryOp and AggBinaryOp; however, since there does not exist a real QuaternaryOp yet - we can leave it as is for now.

      • isGPUEnabled

        public boolean isGPUEnabled()
        Description copied from class: Hop
        In memory-based optimizer mode (see OptimizerUtils.isMemoryBasedOptLevel()), the exectype is determined by checking this method as well as memory budget of this Hop. Please see findExecTypeByMemEstimate for more detail. This method is necessary because not all operator are supported efficiently on GPU (for example: operations on frames and scalar as well as operations such as table).
        Specified by:
        isGPUEnabled in class Hop
        Returns:
        true if the Hop is eligible for GPU Exectype.
