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:
checkArityin classHop
-
getOp
public Types.AggOp getOp()
-
setOp
public void setOp(Types.AggOp op)
-
getDirection
public Types.Direction getDirection()
-
setDirection
public void setDirection(Types.Direction direction)
-
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.
-
constructLops
public Lop constructLops()
- Specified by:

getOpString
public String getOpString()
- Specified by:

allowsAllExecTypes
public boolean allowsAllExecTypes()
- Specified by:

-
isMultiThreadedOpType
public boolean isMultiThreadedOpType()
- Specified by:
isMultiThreadedOpTypein classMultiThreadedHop
-
refreshSizeInformation
public void refreshSizeInformation()
Description copied from class:HopUpdate the output size information for this hop.- Specified by:
refreshSizeInformationin classHop
-
isTransposeSafe
public boolean isTransposeSafe()
Description copied from class:HopDefines if this operation is transpose-safe, which means that the result of op(input) is equivalent to op(t(input)). Usually, this applies to aggregate operations with fixed output dimension. Finally, this information is very useful in order to safely optimize the plan for sparse vectors, which otherwise would be (currently) always represented dense.- Overrides:
isTransposeSafein classHop- Returns:
- always returns false
-
clone
public Object clone() throws CloneNotSupportedException
- Specified by:
clonein classHop- Throws:
CloneNotSupportedException
