Constructor Detail

DnnOp

public DnnOp(String l,
             Types.DataType dt,
             Types.ValueType vt,
             Types.OpOpDnn o,
             ArrayList<Hop> inp)

Create a hop from the builtin expression

Parameters:

l - name of the hop

dt - datatype (only supports matrix datatype)

vt - valuetype (only supports matrix valuetype)

o - type of this hop

inp - input hops

Method Detail

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.

Specified by:

checkArity in class Hop

getOp

public Types.OpOpDnn getOp()

getOpString

public String getOpString()

Specified by:

getOpString in class Hop

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.

isMultiThreadedOpType

public boolean isMultiThreadedOpType()

Specified by:

isMultiThreadedOpType in class MultiThreadedHop

constructLops

public Lop constructLops()

Specified by:

constructLops in class Hop

setOp

public void setOp(Types.OpOpDnn op)

isStride1Pad0

public boolean isStride1Pad0()

constructDnnLops

public Lop constructDnnLops(LopProperties.ExecType et,
                            ArrayList<Hop> inputs)

allowsAllExecTypes

public boolean allowsAllExecTypes()

Specified by:

allowsAllExecTypes in class Hop

refreshSizeInformation

public void refreshSizeInformation()

Description copied from class: Hop

Update the output size information for this hop.

Specified by:

refreshSizeInformation in class Hop

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in class Hop

Throws:

CloneNotSupportedException

compare

public boolean compare(Hop that)

Specified by:

compare in class Hop
