Method Detail

checkArity
public void checkArity()
Description copied from class:HopCheck 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.- Specified by:

getOp
public Types.OpOp2 getOp()
-
setOp
public void setOp(Types.OpOp2 iop)
-
setOuterVectorOperation
public void setOuterVectorOperation(boolean flag)
-
isOuter
public boolean isOuter()
-
isGPUEnabled
public boolean isGPUEnabled()
Description copied from class:HopIn 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:
isGPUEnabledin classHop- Returns:
- true if the Hop is eligible for GPU Exectype.

-
allowsAllExecTypes

constructSPAppendLop
public static Lop constructSPAppendLop(Hop left, Hop right, Types.DataType dt, Types.ValueType vt, boolean cbind, Hop current)
-
footprintInMapper
public static double footprintInMapper(long m1_dim1, long m1_dim2, long m2_dim1, long m2_dim2, long m1_rpb, long m1_cpb)Estimates the memory footprint of MapMult operation depending on which input is put into distributed cache. This function is called byoptFindAppendMethod()to decide the execution strategy, as well as by piggybacking to decide the number of Map-side instructions to put into a single GMR job.- Parameters:
m1_dim1- ?m1_dim2- ?m2_dim1- ?m2_dim2- ?m1_rpb- ?m1_cpb- ?- Returns:
- memory footprint estimate
-
refreshSizeInformation
public void refreshSizeInformation()
Description copied from class:HopUpdate the output size information for this hop.- Specified by:
refreshSizeInformationin classHop
