Class ParForStatementBlock

java.lang.Object

org.apache.sysds.parser.LiveVariableAnalysis

org.apache.sysds.parser.StatementBlock

org.apache.sysds.parser.ForStatementBlock

org.apache.sysds.parser.ParForStatementBlock

All Implemented Interfaces:

ParseInfo

public class ParForStatementBlock
extends ForStatementBlock

This ParForStatementBlock is essentially identical to a ForStatementBlock, except an extended validate for checking/setting optional parfor parameters and running the loop dependency analysis.

getReadOnlyParentMatrixVars

public List<String> getReadOnlyParentMatrixVars()

determineDataPartitionFormat

public ParForProgramBlock.PartitionFormat determineDataPartitionFormat(String var)

Determines the PDataPartitioningFormat for read-only parent variables according to the access pattern of that variable within the parfor statement block. Row-wise or column wise partitioning is only suggested if we see pure row-wise or column-wise access patterns.

Parameters:

var - variables

Returns:

partition format
