Class DataGenOp

  • All Implemented Interfaces:

    public class DataGenOp
    extends MultiThreadedHop
    A DataGenOp can be rand (or matrix constructor), sequence, and sample - these operators have different parameters and use a map of parameter type to hop position.

      • checkArity

        public void checkArity()
        Description copied from class: Hop
        Check whether this Hop has a correct number of inputs. (Some Hops can have a variable number of inputs, such as DataOp, DataGenOp, ParameterizedBuiltinOp, ReorgOp, TernaryOp, QuaternaryOp, MultipleOp, DnnOp, and SpoofFusedOp.) Parameterized Hops (such as DataOp) can check that the number of parameters matches the number of inputs.

      • 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
        true if the Hop is eligible for GPU Exectype.
