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

isRowLowerEqualsUpper

public boolean isRowLowerEqualsUpper()

isColLowerEqualsUpper

public boolean isColLowerEqualsUpper()

setRowLowerEqualsUpper

public void setRowLowerEqualsUpper(boolean passed)

setColLowerEqualsUpper

public void setColLowerEqualsUpper(boolean passed)

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.

constructLops

public Lop constructLops()

Specified by:

constructLops in class Hop

getOpString

public String getOpString()

Specified by:

getOpString in class Hop

allowsAllExecTypes

public boolean allowsAllExecTypes()

Specified by:

allowsAllExecTypes in class Hop

computeMemEstimate

public void computeMemEstimate(MemoTable memo)

Description copied from class: Hop

Computes the estimate of memory required to store the input/output of this hop in memory. This is the default implementation (orchestration of hop-specific implementation) that should suffice for most hops. If a hop requires more control, this method should be overwritten with awareness of (1) output estimates, and (2) propagation of worst-case matrix characteristics (dimensions, sparsity). TODO remove memo table and, on constructor refresh, inference in refresh, single compute mem, maybe general computeMemEstimate, flags to indicate if estimate or not.

Overrides:

computeMemEstimate in class Hop

Parameters:

memo - memory table

refreshSizeInformation

public void refreshSizeInformation()

Description copied from class: Hop

Update the output size information for this hop.

Specified by:

refreshSizeInformation in class Hop

isAllRows

public boolean isAllRows()

isAllCols

public boolean isAllCols()

clone

public Object clone()
             throws CloneNotSupportedException

Specified by:

clone in class Hop

Throws:

CloneNotSupportedException

compare

public boolean compare(Hop that)

Specified by:
