Class TernaryOp

All Implemented Interfaces:
ParseInfo

public class TernaryOp extends MultiThreadedHop
Primary use cases for now, are quantile (<n-1-matrix>, <n-1-matrix>, <literal>): quantile (A, w, 0.5) quantile (<n-1-matrix>, <n-1-matrix>, <scalar>): quantile (A, w, s) interquantile (<n-1-matrix>, <n-1-matrix>, <scalar>): interquantile (A, w, s) Keep in mind, that we also have binaries for it w/o weights. quantile (A, 0.5) quantile (A, s) interquantile (A, s) Note: this hop should be called AggTernaryOp in consistency with AggUnaryOp and AggBinaryOp; however, since there does not exist a real TernaryOp yet - we can leave it as is for now. CTABLE op takes 2 extra inputs with target dimensions for padding and pruning.

    • getOp

    • 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.
