Package org.apache.sysds.hops

Class DataOp

java.lang.Object

org.apache.sysds.hops.Hop

org.apache.sysds.hops.DataOp

All Implemented Interfaces:

ParseInfo

public class DataOp
extends Hop

A DataOp can be either a persistent read/write or transient read/write - writes will always have at least one input, but all types can have parameters (e.g., for csv literals of delimiter, header, etc).

Method Details

hasOnlyRDD

public boolean hasOnlyRDD()

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

setFileFormat

public void setFileFormat(Types.FileFormat ft)

getFileFormat

public Types.FileFormat getFileFormat()

setInputBlocksize

public void setInputBlocksize(long blen)

getInputBlocksize

isRead

public boolean isRead()

isWrite

public boolean isWrite()

isPersistentReadWrite

public boolean isPersistentReadWrite()

isFederatedDataOp

public boolean isFederatedDataOp()

Description copied from class: Hop

Checks if the hop is a DataOp with federated data.

Overrides:

isFederatedDataOp in class Hop

Returns:

true if hop is a federated DataOp

public String getOpString()

Specified by:

getOpString in class Hop

allowsAllExecTypes

public boolean allowsAllExecTypes()

Specified by:

allowsAllExecTypes in class Hop
